Well worth the price! - The meter feels solid and well constructed. The plastic is thick and study (no creaking or flimsiness). The battery compartment has a proper O-ring and the rest of the unit looks to be sealed with glue/silicone. Nice Japanese OEM batteries are included so it's ready to go out of the box. It's a bit larger than other meters, but that makes it easier to handle. The lanyard very convenient when taking direct measurements inside larger reservoirs such as 50 gallon drums. Even if you do drop this meter into your reservoir it'll be fine because it's fully waterproof. This meter does not provide exact numeric measurements on a display like some others, but the LED indicators are easy to read and intuitive. If one indicator blinks, then your nutrient concentration is at that level. If two LEDs alternate blinking then the measurement is about halfway between those values. The precision should be enough for any hydroponics system. The meter turns on automatically when it detects water above the minimum PPM and turns off automatically after displaying the reading for a while. There are no controls on the meter. It doesn't turn on when immersed in common tap water, so accidental battery drain isn't a problem. The detector element itself is also very sturdy and easy to clean. I usually rinse it off every few measurements and store it in the protective case. Buy it! Review: Perfect, wonderful, excellent - I bought a cheap brand from from desertcart and I was sorry. It took me a few days to realize what was going on, and by then, some of my plants were dead. The readings started being erratic, but unlike the airplane pilots that crash because they don't trust their instruments, I decided to trust my instruments, and that killed some of my plants. Then I bought this one from Bluelab. Problem solved. You get what you pay for and I know that, and I should have done this in the first place. It turns on when you put it in liquid and it turns off a few seconds after you take it out, to give you time to look at it even more if you want to before it turns off. It comes pre-calibrated and has a 5-year warranty. It's waterproof. It got here in about 8 hours with free shipping, and it came on Father's Day. Not that I want to but I can't figure out how anybody would rate this less than five stars. ## Features - Quickly monitor for precise up and down adjustment of your nutrient (TDS) level in solution to maximize your grow and ensure plants get the balanced feed they need; Measures while mixing nutrients in your tank - Measurement Range: 2 to 36 CF, 0.2 to 3.6 EC, 140 to 2520 ppm (EC x 700), 100 to 1800 ppm (EC x 500); General uses include gardening, hydroponics growing tent and reservoir - Comes factory calibrated (no calibration required) and is fully waterproof; Automatic Temperature Compensation provides consistent reading regardless of any fluctuations in temperature - Combine with pH tester and other meters for full garden nutrients monitoring in water; Other features: Auto off function, no buttons or switches; KIT INCLUDES: AA batteries, Truncheon case, probe care kit sold separately - Made in New Zealand and manufactured by Bluelab, the industry leader in hydroponic testing equipment, built for growers; 5-Year Limited Warranty with proof of purchase ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00348PV6S | | Best Sellers Rank | #25,639 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #5 in Conductivity Meters & Accessories | | Brand | Bluelab | | Brand Name | Bluelab | | Customer Reviews | 4.7 out of 5 stars 1,043 Reviews | | Global Trade Identification Number | 09421024920012 | | Item Dimensions | 15.94 x 1.18 x 1.18 inches | | Item Type Name | Truncheon Nutrient Meter | | Item Weight | 7.04 ounces | | Item dimensions L x W x H | 15.94 x 1.18 x 1.18 inches | | Manufacturer | Bluelab Corporation Limited - Import (NZ) | | Model | TRUNV2 | | Number of Items | 1 | | Part Number | 716050 | | Unit Count | 1.0 Count | ## Images ![Bluelab TRUNV2 Truncheon Nutrient Meter, Digital Conductivity Tester in Water (Scales Include: EC, 500, ppm 700, CF, TDS) Tool for Hydroponic System and Indoor Plant Grow, White - Image 1](https://m.media-amazon.com/images/I/71uyE6Wb38L.jpg) ![Bluelab TRUNV2 Truncheon Nutrient Meter, Digital Conductivity Tester in Water (Scales Include: EC, 500, ppm 700, CF, TDS) Tool for Hydroponic System and Indoor Plant Grow, White - Image 2](https://m.media-amazon.com/images/I/81vXeZXi20L.jpg) ![Bluelab TRUNV2 Truncheon Nutrient Meter, Digital Conductivity Tester in Water (Scales Include: EC, 500, ppm 700, CF, TDS) Tool for Hydroponic System and Indoor Plant Grow, White - Image 3](https://m.media-amazon.com/images/I/81rOkTSUReL.jpg) ![Bluelab TRUNV2 Truncheon Nutrient Meter, Digital Conductivity Tester in Water (Scales Include: EC, 500, ppm 700, CF, TDS) Tool for Hydroponic System and Indoor Plant Grow, White - Image 4](https://m.media-amazon.com/images/I/71Wd9bCcH5L.jpg) ![Bluelab TRUNV2 Truncheon Nutrient Meter, Digital Conductivity Tester in Water (Scales Include: EC, 500, ppm 700, CF, TDS) Tool for Hydroponic System and Indoor Plant Grow, White - Image 5](https://m.media-amazon.com/images/I/711ZJRatt6L.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: What is the difference between the Bluelab Truncheon and the Bluelab Commercial Truncheon?** A: Both items measure conductivity across all scales: EC, ppm 500, ppm 700 & CF. The original Truncheon (the page you are on) measures in tighter increments, while the Commercial Truncheon (the other option) measures a wider range, up to 6.0 EC. **Q: Who is this for?** A: The Bluelab Truncheon is designed for growers who use batch tanks and/or who hand-mix their nutrients. It's rugged design allows you to use it as a stir stick while you mix your solution, getting instantaneous conductivity readings at the same time. **Q: Who designed the Truncheon?** A: We did! This is an original proprietary design by Bluelab, built on our over 30 years of growing & hydroponics experience. Each Truncheon is built, calibrated and tested by our trained technicians in New Zealand. Please beware of imitations. **Q: You say that this is a nutrient meter designed to last a lifetime. Can you tell me more?** A: The Bluelab Truncheon has been built tough to withstand the day to day rigors of growing and is virtually indestructible. It is fully waterproof, does not need to be calibrated, and only needs a simple rinse after each use. **Q: There doesn't seem to be an "on" button. How do I turn it on?** A: The Bluelab truncheon was designed to work effortlessly right out of the box. It auto detects when placed in liquid, with bright LED lights showing the measurement. No calibration is required, and the Truncheon is super easy to clean & disinfect. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very sturdy.
