I am a Deputy Fire Chief, and purchased this multi-channel thermocouple thermometer to use in a fire training event. We constructed a small model of a building to demonstrate fire behavior and ventilation impacts. The “building†has 4 “rooms†and an attic. The lead instructor thought it would be neat to be able to measure the temperature in each compartment as part of the demonstration. A brief search on Amazon led us to this item.The reviews were decent, though several indicated an innaccuracy of 10-15F. With our use, and the temperatures we would be measuring, we decided that was perfectly acceptable. For the less than $40 price (in March of 2023), it seemed worth the try, and the return policies minimized the risk.Overall, I am very impressed, and so were the firefighters. Having the simultaneous temperature for all 4 compartments added a significant piece of understanding to the demonstration. We reached temperatures of over 1,500F during the experiment, and the thermocouple leads survived. I did not expect that at all. The unit is simple and easy to use, setup was quick, the tester is rugged, ergonomic and durable, the leads clearly hold up to high temperatures, and the display is clear. My only complaint is that the leads are pretty short, around 3 feet or so. We definitely could have used 2-3 times that. I don’t recall the lead length being clearly described in the listing, or I would have likely tried to get longer ones. The good news is if you want longer, higher temp ratings, or just replacements, there are plenty of other leads available.Certainly not a precise scientific instrument, it doesn’t meet any real calibration standards, but in our experience it worked very well for our amateur application.I’ve included photos that show temperature readings at different times in the demonstration, the thermocouples post-demo, and the burn box we used.

This seems to work well. It comes with 4 probes, a nylon zipper case, and a 3 page instruction manual, in relatively good English. Everything about the main unit seems good.The four included probes seem to be poor quality. They seem fragile, with very thin cables, and unenclosed ends. They seem to give equally slightly wrong results across several test temperatures. They consistently read about 4 C low. For example, boiling water (about 10m above sea level) reads as 96C. There are absolutely no specifications for the probes, so I have no idea of their temperature range. The range of the reader is listed as -200C to 1372C, but nothing is said about the probes. They seem to be the cheap "tiny metal ball" type, so they're probably only good to about 250c, but there's no way to tell.

A really nice instrument for the modest price. Calibration is not traceable to NIST or any other standard I am aware of. It works fine for candy making, baking, brewing, smoking, grilling, incubators, and refrigerant measurements. Which are the uses I need it for. If you are trying to prove net energy release from tabletop cold fusion, maybe get something calibrated to a recognized standard. Comes with four basic type "K" bare bead thermocouples. The supplied thermocouples have polymer insulation, so not great for much above 230 degrees F. for extended periods. The supplied thermocouples do work fine for refrigerant line measurements. I bought inexpensive bare bead thermocouples with ceramic insulation, that easily withstand my 550 degree bread oven. A probe with a pointed stainless steel tube is nice for grilling, and similar baking, brewing, type purposes where you insert it. One problem will miniature type K, thermocouple connectors (The little 2-pin yellow plugs) is they tend to get lose with use, especially if you accidentally force one into the receptacle backwards. Nice handy instrument, with a quality look and feel.

In several reviews of this product, people are complaining about poor accuracy. What people fail to realize is that accuracy is a function of the thermocouple you are using, and NOT the thermocouple reader. All a thermocouple reader does is convert the voltage across the thermocouple to a temperature reading. If the thermocouple isn't producing an accurate voltage, then you are going to get an inaccurate temperature reading.If you want highly accurate results, put your money into a high quality thermocouple probe. But using a cheap reader like this is just fine. In fact, you can make your own highly accurate thermocouple reader with an Arduino and a few parts. The magic sauce for accuracy is the actual probe.You can turn off the auto-power-off function of this reader, which is very convenient.This is a decent quality four channel reader that supports several different probe types at a reasonable cost. I've been using mine for a bit over a month now with zero complaints.

very well constructed, this is an excellent device, I changed the actual thermometer probe, the one provided are only accurate to 200 degrees cel, I purchased a better grade probe to use in a coffee roaster, and it gives very accurate readings, the new probe is easy to use in the roaster, I have got very good results roasting coffee beans. The only negative is the device turns itself off after ten minutes but not a deal breaker

The device itself seems to work OK, but only one of the four probes works.

I have two sensors together. They sense different temps. Using a probe that is water proof the water freezes at 0°C fine.The same water boils at 92 on one probe and 98 on the other. Rolling boil shoild be 100°Mash temp for beer at 152 using a calibrated thermometer reads 152. This junk reads 150 and 146 on two probes litterallu tied togetherIf I turn it off for a minute but keep probes in place at a stable temp when you turn it back on they read more than 30°C out then takes 15 minutes to get close but never gets to the actual temp.There seems to be no means to calibrate either

Not happy on this product, second time trying, new batteries but for some reason these numbers are right off T1 says 7.3°C but it’s in -10°C solution and I know it’s -10 from the PLCT4 is in a hotter solution my PLc says it’s 57.2°C not 43.7°C,Not happy please email me this is unacceptable!!
