Thermocouple Thermometer HVAC Temperature Meter, Digital Temperature Thermometer with 4 K Type Thermocouple, Dual Channel Temperature Gauge with Alarm & ADJ Compensation (-328~2500℉ Measuring)

Works great and cheaper than the big name test meters

Works fine so far, did a lot of 1 hour continues test with it and all good, only down side a backlight would had been nice to have.

For this price it had the most features i was interested in:Two type of thermo sensorsAbility to adjust displayed temperature (cheap calibration, e.g.: with cooking water)Ability to diplay temperature difference between both sensorsSmall

What would one expect for a $30-class handheld readout coming with 4 probes when a single quality probe easily cost twice that much alone?"Q.E.D.", I thought, and ordered it, knowing the odds. And I was neither dissapointed nor surprised.After arrival, my very first test: ice water - and it read -4.4 deg. C. UhOh... Okay, lets zero it, Manual describes the procedure. Well, -0.4 deg C was the closest I could get as a chain. good enough...Second test: bring the water to a boil: something like 91 deg. C. Oh? Well, did not read the barometric pressure but it still looks awkwardky off. But hey, that is nothing exact either, I shrugged it off, waiting for the next day in office.So, in office I had to do some calibration work to do and a Fluke 5502A at hand. That will show some realistic values. And it did (after zeroing it once more): please see the attached calibration sheet. Surprisingly accurate between 0 and 75 degrees C but totally out-of-spec over Full Scale.And please keep in mind: that was only the device. The dry well and the process calibrators at work were not available, so the probes are not even in the equation - but I have a bad feeling about them.So, what use are all fancy features of usability/readability on a device that does not even perform its basic task: give accurate readings. I will save myself the hassle of returning it and give it to the kids as a toy: They are not supposed to work unsupervised with temperatures outside the accurate range.At the end of the day: cheap toy, unusable otherwise.Recommendation: STAY CLEAR, DO NOT BUY!

I bought this thermometer because my wife was telling me the electric oven wasn't getting as hot as the set point. Reading the old analog thermometer was too difficult as the eyes aren't what they used to be. I believe this little unit is more than accurate enough for most readings as K thermocouples are pretty accurate. It's very easy to set up and operate. It came with two wire thermocouples and two probe thermocouples. A good deal!

Interface is easy to use, I need to work with the high/low recording settings.As another reviewer said, its really only accurate from 32F to 200F. It reads a block of ice stored at OF as 18F and a block of ice stored at 10F as 25F.

I’ve had this for several months now. Works great. Dual temperature probs, with differential display. Also bought a pack of strong rare earth magnets about a size is a dollar coin with double sided tape. Now hands free.

Returning product, hard to calibrate / the instructions are not accurate for this unit. Probes are junk.
