It includes an 18-inch remote probe for hard-to-reach measurements, programmable audible and visual alarms for humidity alerts, and min/max memory with reset. Field calibration ensures accuracy, making it ideal for labs, storage, and controlled environments requiring precise climate monitoring. ## Description From the manufacturer Extech Instruments Big Digit Humidity Alert with Limited Nist Ideal for monitoring environmental conditions in laboratories, storage areas, manufacturing assembly areas and other controlled environments, the Extech Humidity Alert Meter emits visual and audible warnings when humidity levels exceed high or low limits. The metre features a remote probe that can extend on an 18 inch cable so the user can take measurements behind walls, in ducts or other areas that are difficult to access. Unlike other humidity indicators the 445815 calculates and displays the Dew Point reading which is a calculation of temperature and humidity used to determine when condensation will occur. The 445815 also features a large digit LCD screen, which allows for the simultaneous display of humidity, temperature and dew point. Safe and clear readings Large LCD display Large triple display of relative humidity, temperature and dew point. Remote probe Remote probe can either clip onto the meter or extend on an 18 inch cable for measuring behind walls. User programmable alarms Alarm with programmable set point gives visual and audible warning when humidity level exceeds high or low preset limit. Mountable Built-in stand for sitting on a desk or mount on a wall using included bracket. Useful data Minimum/Maximum memory Metre recalls minimum and maximum readings and includes Reset function. Accurate measurements Measures humidity from 10 to 99 per cent RH and temperature from 14 to 140 degree Fahrenheit (-10 to 60 degree Celsius) with an accuracy of ±4 per cent RH; ±1.8 degree Fahrenheit. Easy adjustments The 445815 can be field calibrated with the optional calibration kit (Model 445580-C) and has a rear calibration adjustment pot with max/min and a reset function. NIST Certifiable An optional NIST Traceable Certification satisfies ISO and other regulatory body requirements for product accuracy and traceability to nationally recognised reference standards. Review: More expensive then some but well worth it - I bought this after much research and I'm sure I have made the right choice.I suffer badly with COPD and I need a more accurate reading of the air quality in my home so I can set my other equipment to fine tune the air for better breathing ....Firstly...It is very accurate and you also have the ability to calibrate it with the appropriate Kit but it is £30,but remember...DO NOT mess with these adjustment screws unless.A) you know what your doing and B) you own the calibration kit,,They are not there to tamper with otherwise and even when using the screws ,only very small adjustments have to be made each time allowing 30 mins between each adjustment if temp and Dew point is essential then look no further..It also comes with an 18" probe which sits on the side in it's own little holder...this is great for those hard to get to places that need to check if damp has set in. It's real easy to set up and it's quick to respond to the atmosphere around it which is handy as you don't always want to leave it hours on end for results...It's also very well made with a small kick stand at the rear to place on any flat surface..You also have the ability to set a high and low humidity (maybe more for those monitoring technical equipment) and also a reset button to see what changes have occured during the day. I will point out that it IS Green with a silver accent and not black as the main photo shows,but it looks quite smart none the less...£40 gets you a great accurate Temp gauge and Dew point monitor and it does a fantastic job.Highly recommended Review: Reasonable little until - A nice little until, the temperature seems to be quite accurate, not sure about the % of the relative humidity. The the dew point temperature is accurately calculated between the two figures. Maybe it's a bit over priced for what it is? ## Features - RH audible and visual alarm alerts when humidity exceeds set limit - Displays dew point temperature - Maximum and minimum with reset function - Humidity from 10 to 99% - Temperature from 14 to 140 Fahrenheit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000GFCN1I | | Battery Description | Alkaline | | Battery description | Alkaline | | Best Sellers Rank | 190,433 in Garden ( See Top 100 in Garden ) 3,973 in Scanners & Testers 15,005 in Lawn & Garden Watering Equipment | | Brand | Extech | | Colour | White | | Country Of Origin | China | | Customer Reviews | 4.2 out of 5 stars 251 Reviews | | Global Trade Identification Number | 00793950458150, 04016138375534 | | Included Components | Built-in Stand, Wall Mount Bracket, 1 AAA battery | | Item Dimensions W x H | 20W x 109H millimetres | | Item Length | 4.3 Inches | | Item Weight | 0.19 Kilograms | | Item weight | 0.19 Kilograms | | Lower Temperature Rating | 10 Degrees Celsius | | Lower temperature rating | 10 Degrees Celsius | | Manufacturer | Extech | | Manufacturer Part Number | 445815 | | Model Number | 445815 | | Mounting Type | Wall Mount | | Operating Humidity | 10% to 99% | | Product dimensions | 20W x 109H millimetres | | Smart Home Compatibility | Not Smart Home Compatible | | Temperature Accuracy | +1.8 °C | | Temperature Reading Accuracy | plus_minus_1_point_8_degrees_celsius | | UPC | 885866191235 793950458150 | | Unit Count | 1.0 count | | Upper Temperature Rating | 140 Degrees Fahrenheit | | Voltage | 1.5 Volts | ## Product Details - **Battery description:** Alkaline - **Brand:** Extech - **Colour:** White - **Item weight:** 0.19 Kilograms - **Product dimensions:** 20W x 109H millimetres ## Images ![445815 Hygro-Thermometer Humidity Alert, Dew Point, Calibration | Programmable alarms, dew point, triple display, MIN/MAX, field calibration pot, remote probe - Image 1](https://m.media-amazon.com/images/I/61IzukYZWCL.jpg) ![445815 Hygro-Thermometer Humidity Alert, Dew Point, Calibration | Programmable alarms, dew point, triple display, MIN/MAX, field calibration pot, remote probe - Image 2](https://m.media-amazon.com/images/I/716R21jd3GL.jpg) ![445815 Hygro-Thermometer Humidity Alert, Dew Point, Calibration | Programmable alarms, dew point, triple display, MIN/MAX, field calibration pot, remote probe - Image 3](https://m.media-amazon.com/images/I/71gWHX9YtdL.jpg) ## Questions & Answers **Q: Is two degrees hotter normal for this thermometer. The humidity is good but checkiing normal for the product.** A: Not normal. Accurate to within a half-degree when calibrated. **Q: How do we select either of the 2 Certificate of Traceablitity options? Or is this already in the box?** A: The product does not come with a certificate & it's a hassle to obtain. The Extech website notes the following:Is my meter calibrated out of the box? How often should it be calibrated? Does it come with a calibration certificate? How & where can I get my meter calibrated?All Extech products are factory calibrated prior to shipment. This calibration is valid for one year. An annual factory calibration is recommended. Extech does not include calibration certificates with our products. NIST calibrations with data can be purchased for an additional charge for most products. To send your meter to be NIST calibrated please contact our return department for a return authorization number and other return information. **Q: Can it display the temperature in Celsius unit?** A: Yes! Good question, and I did not know, so I dug out my instructions. I am now looking at those and my unit and there is a switch in the battery compartment below the battery for degrees F and degrees C. Using this, I have 78.6 F showing as 25.9 C. BTW, I'm actually considering getting another one for my car and work. It will need some protection, like a plastic sandwich box with some paper towel padding, but that will do it for me. Hope you enjoy yours as much as I like mine. **Q: May i know does this item come together with a calibration certificate?** A: The calibration certificate is not included; it can be ordered together with 17030-28 calibration. ## Customer Reviews ### ⭐⭐⭐⭐⭐ More expensive then some but well worth it *by M***E on 29 August 2016* I bought this after much research and I'm sure I have made the right choice.I suffer badly with COPD and I need a more accurate reading of the air quality in my home so I can set my other equipment to fine tune the air for better breathing ....Firstly...It is very accurate and you also have the ability to calibrate it with the appropriate Kit but it is £30,but remember...DO NOT mess with these adjustment screws unless.A) you know what your doing and B) you own the calibration kit,,They are not there to tamper with otherwise and even when using the screws ,only very small adjustments have to be made each time allowing 30 mins between each adjustment if temp and Dew point is essential then look no further..It also comes with an 18" probe which sits on the side in it's own little holder...this is great for those hard to get to places that need to check if damp has set in.

The the dew point temperature is accurately calculated between the two figures. Maybe it's a bit over priced for what it is? ### ⭐⭐⭐⭐⭐ A1 Monitor - Damp reality *by Q***R on 5 November 2016* No technical advice or comparisons here, I'm no scientist, this monitor works out of the box just pull the tab from the battery compartment to get it started. I needed to find out the humidity levels in the house as it felt cold and a little damp and before investing in a dehumidifier I wanted to see just what was going on, it registered 70% and remained at this level or above for days so I did then invest in a dehumidifier, the interesting thing for me was that this monitor and the reading on the dehumidifier were closely aligned so I knew I did have a damp problem. The dehumidifier did it's job collecting a surprising amount of water, 2 weeks later the humidity in the house is running at 53% and the monitor reflects the same. I know this unit is expensive but I wanted something that gave accurate readings before spending more on a dehumidifier I might not need, I'm glad I bought this it gave the reality needed to understand the house was damp and something needed to happen to make it healthier. There is a lot of science in the other reviews and it does push more for use in computer rooms etc, but if you do want to accurately measure the humidity in your home I would invest in this unit, it's not attractive, it is green but it works and that's all that matters. ## Frequently Bought Together - Extech Digit Thermometer - Extech 445580 Humidity and Temperature Pen Sized Meter with Pocket Clip --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/49155999-445815-hygro-thermometer-humidity-alert-dew-point-calibration-programmable-alarms](https://www.desertcart.com.kw/products/49155999-445815-hygro-thermometer-humidity-alert-dew-point-calibration-programmable-alarms) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-07-21*
