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 β€” 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! ## Features - Support K/J/T/E/R/S/N Type Thermocouples Measurement: Packed with two K-Type thermocouples, this Proster Digital Thermocouple can direct measure the temperature of tested object - Considerable Measuring Range: Can be used to measure the temperature of liquid / vapors and surface temperature of a solid object.Also suitable to be used both in the high temperature fields of blast furnance and cookery and the low temperature measuring for liquefied hydrogen and liquefied nitrogen etc - High Accuracy: K-type Thermocouple Measuring range: -50~300℃ ; Accuracy: 1.5%; Resolution: 0.1℃/β„‰οΌœ1000Β°,1.0℃/℉β‰₯1000Β° - Functional Design: Data Hold Function;MAX/ MIN/ AVG Value Measurement;Auto Power Off; Double display with LCD Backlight shows T1/T2 and combination of T1 and T2 - Wide Applications: Fish tank, pool, furnaces, ceramic, pottery, molten metal etc Test Tips: Five seconds is generally sufficient in a stable ambient temperature environment.

Its accuracy compares well against my other meters. The buttons feel great β€” 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.

And, for a useful piece of test equipment it's really cheap! ### ⭐⭐⭐⭐ Reasonable purchase *by L***T on January 7, 2020* Much of this will be a repetition of previous reviews, but reflects my experience with the product so far. I received the "Proster" yesterday and took it took work with me to see how it held up to our calibrated thermometers and devices at the lab. It held up just fine right out of the box. With most devices, electronic and glass thermometers, it was within 0.5c. Of several devices, I head two outliers. One electronic device that was out of agreement by 1.1c and a glass thermometer in our drying oven that was out of agreement by over 5c. 1.1c is within the combined error for both devices combined, but >5c made me do some additional checking and I believe it is the glass thermometer that we have to do something about as every other device I threw in the oven read within 0.5c of the "Proster." I don't know how it will hold up over time, but this device clearly is comparing favorably to lab calibrated devices so far. It has even likely uncovered a glass thermometer that needs to be replaced and would not necessarily have been noticed until the next scheduled calibration. I call that a win. To be clear, while I have ordered additional probes for various applications, all of my experiences contained in this review were with the default K type wire probes that came with the device. I would go on to mention that both wire probes seemed equally functional, both being within 0.2c of each other nearly the entire time they were placed together in one sample or environment. In the meantime, I find the auto power off and the backlight that goes out after 2 seconds to be downsides and not useful features for me, but overall I would say that it is a good choice for a 20 dollar device that can cover a wide range of temps. Unless I am doing something that requires a NIST certified thermometer or a really tight fractional distillation, I think I would now be pretty comfortable using this device for most other applications. ## Frequently Bought Together - Proster Digital Thermocouple Temperature Thermometer Dual Channel - with Two K-Type Thermocouple Probe, Backlight LCD Thermometer for K J T E R S N Type - Yunsailing Type K Thermocouple Probe Tl1004 K Type Sensor Probes Metal Mini Connector Temperature Sensor for Meter in Temperature Range from 0 to 500 Celsius(3 Pcs) - 5 Pieces 3 Meters K Type Mini-Connector Thermocouple Temperature Probe Sensor K Type Thermocouple Wire Temperature Sensing Line Measure Range -50 to 400 Celsius, Compatible with TM902C/ TES1310 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/42594452-digital-thermocouple-temperature-thermometer-dual-channel-with-two-k-type](https://www.desertcart.vn/products/42594452-digital-thermocouple-temperature-thermometer-dual-channel-with-two-k-type) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-23*
