Thermocouple Thermometer Digital K Type Thermometer HVAC Thermometer Dual Temperature Meter with 4 Thermocouples, MAX/MIN/AVG Temperature Measurement, -50~1300°C (-58~2372°F)

The price was great, and this tool performed even better than i imagined. It has 2 channels. The channels can be displayed individually (1 at a time), or the difference between the two can be displayed. 2 each of 2 different types of sensors (small wires or stainless pointed tube) are included with the meter, so this should fit almost any small temperature measurement need. I have found it to be very handy for my needs.

Great little meter for checking temperatures on stoves and refrigerators.

Seems to be working well enough between 0C and 100C. Will probably work for my purposes and the price is right. Documentation leaves a lot to be desired.So 4 stars right now.However, I am a little concerned that the unit went completely dead after using it a couple of minutes. There is an auto shutoff, but turning on/off did not fix. Changed the battery and it came back. Auto shutoff seems to work now, as it comes back after power button is pressed. So far so good, but still....Factory reset occurs when changing battery - not mentioned in the manual or description.There is no calibration option despite some reviews mentioning it.There is no certification of accuracy, not surprising given the price.Plugs are extremely tight. Requires some care as unit does not seem very sturdy.Actual temperature range is confusing. Temperature range in the manual is 50C (?) to1300C and also says -50C to 400C for "TP01". Am I supposed to know what "TP01" means? Type K thermocouples should be good to at least 1200C.

Works great. Just what I needed at a good price. Maybe not built for durability bc wires very thin but worth it.

Cheap imitation made to look like Fluke but barely works

Overall OK. Make sure the sensor in plugged in in the correct direction. Seems to make about a 2-3 difference at room temperature. The nylon-stainless probes are not labeled +/- that I can see but looks like having the letter K "up" is correct. You mileage may vary.Also, the min/mav/average is non funtional..at least at lower temperatures. Have not have a change to try higher temps yet. When you turn it on (auto off btw - no workaround) if starts at 10-15 deg low and then gives a correct readying after a sec or two. This mean the starting min is ALWAYS wrong and average will be wrong as well. Still trying to decide to call that defective and return it or not.

I bought this to monitor kiln temps, both inside and surface temp. It’s worked fine on two low temp (1000 F) firings. In ice water the probes are with 0.5 degrees. In steam at 14.7 psig they are within a degree.I’m going to buy a ceramic clad sensor for the higher temp of 1850 F. I’m not sure the one supplied will make it without melting the wires.Can’t get back lighting to work at all. But that’s ok. The screen is readable.

A good low cost solution for measuring AC superheat and sub cool.
