Review: Intuitive To Use - Great Technical Support - Very Accurate - Long Warranty - When I first examined, then tested, this instrument I was happily surprised at the quality and accuracy. I originally bought it as a "Sacrifice" device- to be used in rough conditions. Now, I'll keep it for more civilized environments! ACCURACY- Thermocouple thermometers are notorious for being inaccurate at either the low or high end of their range. The included probes are rated for (-) 50 to (+) 300 C. (The actual instrument has a much wider range.) It was tested against two NIST mercury thermometers. Testing near the low end yielded zero error. Warming to 0-C also gave exact readings. Testing at a semi-middle temperature of (+) 20 C showed 0.5 degree error on one thermocouple and zero error on the other. Swapping probes showed it is the thermocouple, not the instrument. Testing near the high end showed some minimal wandering of 0.5 degree. But it wandered +/- the actual temperature. Using other probes, such as other Type-K and some Type J, T & e showed similar excellent results. Testing Note- If you decide to test with boiling water, there are some things to keep in mind: a) Water boils at different temperatures at different altitudes AND the day's barometric pressure will also change the boiling point. Pressurized buildings, such as large office towers, will also change the boiling point. At my shop's altitude on a 760 mm HG (29.9 inches Hg) day, water boils at 99-C. (210.3 degrees F) b) Keep the probe away from the walls & bottom of the container and be sure to keep out of the bubble stream. Testing with an ice bath is not as sensitive to atmospheric or altitude changes. Just be sure to keep off the actual, solid ice and in the water. Even my high-dollar instruments have some variance in accuracy- some more than this Proster. If you need more accuracy, an analog mercury or alcohol thermometer- and a barometer & chart- will be essential. TECH SUPPORT- Although this instrument is very intuitive to use, I had a couple of questions of a "geek" nature. Belle from Proster answered quickly and and explained well. She was also kind enough to send me a digital copy of the owner's manual when I explained that my vision prevented me from reading the printed manual. (Yep- You get an actual printed manual. Who else does that? Nobody!) EASY OF USE & BUILD QUALITY- The buttons are huge, so even I can read them. They have legible markings. The screen is also very large. The case looks sturdy, although I don't plan on testing it's strength! Even the box it came in is heavy-duty. Without reading the manual, it is easy to figure out what each button accomplishes. The included batteries (Included batteries = A nice bonus) have lasted over 20 hours so far and are still going strong. WARRANTY- The manual says it has an 18 month warranty. Cool, huh? For something that cost 25.00 USD, that is surprisingly long. (And I understand from others that Proster does honor their warranties.) Personally, I bought it with a credit card that gives an additional 2 years. So now I have 3-1/2 years warranty for a $25.00 device. SUGGESTIONS- It would be great if the auto-time-off could be adjustable. It is either 1 minute or always on. A back-light timer adjustment would be helpful. Mine times out in 4 seconds. (But if it could be longer, I'd complain about short battery life...) WOULD I BUY IT AGAIN? Yes- For certain. I like it so much that I upgraded it from "harsh conditions use" to "be nice to it use". And, I'll even put a screen protector on the display. Actually, I plan on purchasing some more for myself and friends. NO I DONT... I don't work for Proster, nor do I know anyone there. I don't work for desertcart, either. I'm just an end user with much temperature measurement experience and education, so I wanted to post an un-biased review of performance, along with my non-scientific opinions about ease-of-use, warranty & stuff like that. Thank you for taking the time to read my overly long review. I hope it helps you decide if this instrument is correct for your projects!
Review: Very satisfied - I'm very satisfied with this product. It works well. Its accuracy compares well against my other meters. The buttons feel great — with adequate travel and a real click! There are no weird modes invoked by weird sequences of long presses and multi-clicks, so operation is very straightforward. The display is large and clear, and when the backlight is on is adequately bright. The battery compartment has a spring clip (which is easy to use, not a screw (which I hate) holding it closed. It's comfortable to hold. It's attractive, and the buttons are easy to read. And, for a useful piece of test equipment it's really cheap!

## Questions & Answers

**Q: Can the probe's plastic insulation be stripped back an additional 2". Would like to place end of probe between to aluminum plates**
A: Yes they can.

**Q: How long are the probes?**
A: The probe leads are just over 40” k type thermistors. For the money this is a good tool to have. 
For any  Critical temperature measurements I use the copper brand

**Q: Does this thermometer have a user calibration option? Does it have cold junction compensation?**
A: Not that I know of. A digital thermometer, that, depending on the probe, can measure extreme heat and cold.

**Q: Would this make a good field thermometer - subject to wet conditions?**
A: Not sure about the unit itself the probes can be put in water.

### ⭐⭐⭐⭐ Almost great, still a good purchase
*by T***M on June 20, 2024*

I was too cheap when I bought my Fluke multimeter to get the version that supported thermocouples last year and found myself needing something reasonably accurate. Did not need super precision, logging, or an accompanying phone app so the Proster seemed to fit the bill. The user interface is logical and the display is legible. Temp accuracy is within the promised spec and the interface electronics provide good tracking between thermocouples. I do have a couple issues, however. The instructions state that you can disable auto shutdown by pressing/holding the Hold button. Never got this to work and was important to me since I wanted the AVG function to integrate over longer periods. Also, one of the thermocouples appear to have a bad tip weld since initial testing showed widely varying readings when the cable was moved. No issues if you're careful and keep the cable still but it's still a defect that I've never seen in higher quality products I used to used. All in all, reasonably happy with the product given the price. If I saw the two issues on higher end units, they would get returned.
