Proster Digital Thermometer Dual Channel - K-Type Thermocouple Temperature Meter -50℃~1300℃ with 2 Probe, LED Backlight & Hold Data Thermocouple Thermometer for HVAC, Pool, Pottery & Industrial Use

Since this unit was so cheap, I it didn't expect much from it. Thermocouple based temperature devices are a bit tricky to design since the generated EMF is so small and you need a good design and good part to get an accurate reading. I just turned the unit on and the temperature read the same as the my digital wall clock-thermometer. If the probe tips are in the same place, then both channels read the same temp within 0.1 to 0.2 degrees. This is hardly a scientific test but this kit isn't going into a lab. Happy with the product.

Nice, good for checking liquids, surfaces and ambient temeratures that a DIYer like me might encounter (so far). Reads about 0.9 deg C low at 37 deg compared to a decent medical thermometer. The main reason I suspect that it's a bargain is no rigid housing for the thermocouple tip, but that's offset by having a spare in the box. Fingers crossed it'll be reliable.

Fantastic bit of kit, I use this for measuring the temps of car AC and heating from the vents. Very clear and easy to use

Good value for money, perfect for setting up radiators

I bought this device, together with two clamp type connectors, to balance the radiators in my house. The device was easy to use, although the instructions were very basic and simply explained what each thing was, as opposed to the correct use of it. Nevertheless, I was able to use it more or less straight out of the box. I haven't tested it's accuracy, as others have by exposing the probes to a boiling kettle and ice, as I was happy with the readings I got from the central heating system. Radiator balancing is time consuming but even so this is far cheaper than getting a plumber in, and given some of the plumbers we've had in the past, it's more precise in its work too.

This item is unusable as the temperature constantly fluctuates which does not enable me to get an accurate temperature. It can change 10°C in a second.

Nice little meter easy to use not the most robust but what do you expect for this money I would recommend for testing of domestic hot and cold temperatures as well as flow and return cross tempratures with k type clamp clips

As described. Good price. Basic quality but good value, fine as a hobby device. Arrived on time.
