The thermometer itself operates as expected, but the probes are a joke. They can’t handle high heat and ended up melting, which defeats the whole purpose. If you need something for serious cooking or grilling, look elsewhere. One star for functionality, but the cheap probes make it worthless.

works as advertised

This is my second unit, as the first lasted about 2 years with very limited usage.

I was looking for a relatively inexpensive temperature gauge where I could monitor line set temperature on AC systems. Add a set of clamps to the setup and it is super-easy to use. The price is good and it works as designed. It is easy to switch between Centigrade and Fahrenheit, so it is easy to adapt to your needs. Recommended product and company.

Worked with temperature probe I bought, was able to compare measurements with Arduino input. seems pretty accurate. For more durability, add a metal-cable probe as the default probe is not suitable for high temperatures like ovens, etc.

I think I connected wrong poles of thermocouple and that was the problem - but the return was so straightforward

My GE oven did not seem to control the cooking temperature well so I purchased the Type K digital probe and now I can adjust my oven to the exact temperature required. Accurate (I checked the instrument at boiling and in ice water) and it works great.

Made of very cheap plastic, no protection and very slippery. First use I dropped it while work on my knees, so maybe 12-18" and cracked the screen. I wrapped the outside with electrical tape for a better grip. It works and was accurate enough to balance the flow on a pool heat exchanger. Thermocouples are just as cheap. You get what you pay for! If you need this for daily use, buy an Extech, Fluke or Fieldpiece.

Right from the box I ran through the settings of probe type (=K), and Temp scale (=F) - very simple to do, and all settings remain as they were at last power-off.The room temperature initially read 73.4F and 79.1F, but after 30 seconds or so, they settled down to readings of 70.1F and 70.1F. Over the next half an hour, one reading or the other would briefly move up or down by +/- 0.1 or 0.2, but always returned to 70.1. During this time, I cycled the power every few minutes to see how the meters started back up. There was only a second or two of settling time with each power-up. I left the probe ends in place, close together and weighted down to the floor by a book. Handling the meter body had no effect on the readings. Unplugging and switching the probes made no difference.Comparing to my trusted Fluke 80T probe I have used since 1982 or so (and was last calibrated in 2007), the Fluke measured room (floor) temperature reading is 70.0F.Based on my experience with thermocouple probes supplied with various multimeters I own , this is extraordinarily stable and precise, as well as accurate at at least one point. This result is not something anyone should expect from a mass-produced thermocouple thermometer - especially an inexpensive one. Probably I was just lucky - but at least it shows that such performance is possible from this instrument.I plan to make accuracy tests with an ice bath and with boiling water, and tracking precision tests with refrigerants such as CO2 and with a hot air gun. I will use a variety of probes as well as the ones supplied.I think it highly unlikely that the two probes will track so perfectly over a wide range of temperatures, but this single point test is encouraging. I will update this review after I perform further testing.**** UPDATED****I did some further testing, using the probes supplied. I twisted the probe ends together so they would be in the same environment.In an ice water bath The two probes read 33.8F and 34.1F after stabilizing for about 2 minutes.In my home freezer (set for -5F), The probes read -5.1F and - 4.8F.In boiling water, they stabilized at 211.7F and 211.1F.I tried to read my oven, set to 300F, but I couldn't get a stable reading. It turns out that the oven cycles on and off fairly frequently, and the temperature swings high, then low as it does and the probes can't keep up.Manufacturing variations result in the sensing beads on the two probes being visibly different in size - about 2:1 in diameter. The larger bead is much slower to settle than the smaller bead. As the temperature is swinging up and down, the difference in readings becomes large, only settling once the temperature becomes constant for a minute or so.Probably by selecting two thermocouples from the same manufacturer's batch that have nearly identical junction beads, the probes would track well. I ordered a set of ten probes to use in that way.

Nothing fancy, but it certainly does the job and at a great price.

Pas precis,erreur de 1 degre voir 1,2 ....a voir avec d'autres thermocouple,ceux la sont de faible qualite...je ne n'attendais pas de miracle pour le prix....si encore on pouvait le calibrer....mais non....

Works very well and is easy to use. The plugs are a tight fit into the machine, a bit too tight but better than too loose and dropping out. All in all a very good thermometer.

I purchased this thermometer to take temperature measurements around the house and just to have a toy to tinker around with. I am not using it for any industrial or scientific purposes that require super high accuracy. If that's what you want, then you need to spend the money necessary to achieve that (i.e go buy a Fluke). You're simply not going to get that for $17.After I opened the box, I decided to test the accuracy, so I put a pot of water on the stove and brought it to a boil. I stuck the leads in the center of the pan (without touching the sides or bottom) and both leads read 209.1°F and stayed there. I checked the barometric pressure (since the boiling point of water varies with pressure) and I determined that the water in my area should boil at 211°F. So, I figure that this thermometer's accuracy is within 2°F to 2.5°F, which is good enough for me. Sure, I wish it was reading dead on accurate, but the good news is that both leads read exactly the same in the boiling water, so there's no variance at all there (like is the case with some cheap thermometers that give different readings on the different leads).Pros:CheapFairly accurateBoth leads read exactly the same during the boil test (209.1°F).Nice buttonsDecent build qualityDoes min/mean/max readingsHas a hold functionCan use almost any type of thermocouple (K, S, E, J, etc.. etc..)Cons:Inaccurate by around 2°FThe backlight cannot be controlled, it only comes on for a few seconds after a button press. I would like the option to turn it on for as long as needed or for it to have a longer cut-off time.Has a cutoff of around 3-4 minutes (I didn't check exactly). Sometimes cuts off right in the middle of a reading which is annoying.Cannot be calibrated and you cannot create offsets (i.e. you can't do manual error correction by adjusting it to a known temp).Overall:The pros outweigh the cons and it's definitely worth $17. This thermometer is made in China and no other developed country would be able to produce a thermometer like this that retails for $17. So, all of us in the west should take advantage of China's generosity before they develop further and their people begin demanding 401K's, $40 an hour, full medical and dental, and pension plans like us Americans. It will happen at some point, so get while the getting is good.
