Proster Digital Thermometer Dual Channel Thermocouple Thermometer with Two K- type Thermocouples Temperature Meter Gauge with LED Backlight for K/J/T/E/R/S/N Thermocouple

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.

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.

I have tested it for the first time in my small pottery kiln, up to cone 03 and it registered as 1097 centigrade, about right. Very good value for money.

Brilliant. Works really well.

used for checking the temperature on radiators. Easy too use.

Like a lot of folks reviewing this product, I bought this (along with a pair of pipe clamp probes) to help me balancing radiators in my central heating system and, like others, I've discovered a weird issue where on most of my radiators, connecting the second probe to the pipework causes a drastic and immediate change to the temperature registered on the first probe. Removing the second probe allows the first to return to its original reading.You just have to be wary of this if using this device for this purpose and work around it. It just makes the "dual channel" aspect of this unit less useful.

Good device, works fine and as suppose. Quite fast reading speed. However the smell of plastic or what is smells just weird. Another annoying point, is a traces of anti-shock cover on the plastic body of device. Anyway, no complains for a work, I would give 4.5 stars if I could, -0.5 just because of aesthetic side.

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.
