Your cart is empty.Here’s the perfect thermometer for wet areas. Case is waterproof and shockproof. Use for round-the-clock monitoring of liquids, air/gas, or semisolids in freezers, water baths, outdoor tanks, incubators, and refrigerators. Stainless-steel probe is resistant to most laboratory chemicals. Wide temperature range: Wide range covers 99 percent of the lab’s routine temperature measurements: Range is -50 to 300 degree C with a resolution of 0.1 degree from -19.9 to 199.9 degree (otherwise 1 degree). Accuracy is +/-1 degree C between -20 and 100 degree C. Ultra model accuracy is +/-0.5 degree C at tested points. Easy-view, 1/4" high LCD digits may be read with a glance. Records minimum/maximum readings: At the touch of a button, memory recalls highest and lowest temperature readings over any time period. Reading updates every second. Solid-state construction eliminates dangers inherent in breakable glass and toxic mercury thermometers. All-weather compatible: Thermometer operates without fail in rugged conditions and outdoors. Waterproof construction is ideal for wet labs, wash-down areas, and virtually all field applications. Unit is engineered to be shockproof in drop tests up to 5 feet. Stainless-steel, 4-3/4" long, 0.14" diameter probe, 10-foot cable, and digital-display housing are all waterproof. Traceable to NIST for accuracy: To assure accuracy an individually serial-numbered Traceable Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). May be placed anywhere: Supplied with suction cups, magnet to attach to metal, and Velcro to attach to any surface. Comes with Traceable Certificate and 1.5 volt silver-oxide battery for 1-year, continuous, always-on monitoring. Size: diameter is 1-3/4" and depth is 1/2". Weight is 2 ounces.

Above all the reason most would get this digital thermometer is because it's allegedly NIST accurate.NOPE....IT IS NOT!!!! We bought 5 different thermometers, all with NIST certification (but most more expensive than this one). This one was off by almost 7C!!!!! Do not buy! If this was only $10 I wouldn't buy! Maybe $5 or less and the exact temp didn't matter to you...maybe? Free might be the only way I would ever consider something this useless and cruddy. THEY LIED about NIST accuracy. Period. Disqualifying, especially at the price this is listed for.

I bought this for our audit but when compared with another certified thermometers we purchased it was the only one that was different

Worked perfectly. Great that it is leak/waterproof as that is what ruined my other thermometer. Glad I got it.

I use this thermometer for homebrewing and I love it! it reads temperature accurately and it has a long cord and can be submerged in hot and boiling wort no problem. just be careful pulling on the cord because it can dislodge from the probe and ruin the thermometer.

I bought this item to monitor temperatures for Home-brewing beer. I used it once and it worked like a champion, however, pulled it out the second time, and it was reading 154 degrees F for room temperature. I replaced the battery like the manual suggests with no change. Unfortunately its been 3 months since I ordered the item so I can no longer return it. I have emailed the Thomas company to see what can be done now. If I get good feedback/repair/replacement I'll update this review but for now, as it stands it's not a very reliable device for the price tag.UPDATE: They did replace the thermometer for no cost. It took a couple weeks to get it taken care of, some E-mails, and shipping costs. We shall see how this new one holds up.

This item arrives with an official looking calibration sheet, etc., etc. I was fooled twice, but won't be again. I use thermometers to monitor the water temperature when I "hot-dip" my oyster stacks to kill the bio-fouling, but not the oysters. The stacks, with oysters in them, get dipped in a huge vat (112 cubic feet) of water heated to 140-degrees (F) and held there for 40 seconds exactly. A little too hot or too cold will either kill the oysters or won't kill the bio-fouling. The 1st one of these items I bought was used 1 time and, halfway through the hot-dip, the item went haywire and started climbing. Since I use three different thermometers simultaneously for just such a failure, I was able to disregard the item. I thought the failure might have been due to a cracked wire leading to the probe, so, 8 months later when I got ready to do the hot-dip again, I ordered another one of these items. This one was even worse. The other two thermometers (Taylor Digital Waterproof Maximum/Minimum Thermometer, -20 to 120 Degrees F and a General Tools AQ150 Digital Aquarium Thermometer ) were within 8 degrees of each other (the Taylor is my new standard, since it has two probes and is within 1 or 2 degrees of the liquid thermometer I use to calibrate them with). The new Thomas item, while it didn't vary in its readings, was 38-degrees too high the entire time! If you are willing to do a calibration test yourself (using ice water for example), and then add or subtract the error while you are working, this item might be OK. But why bother when the other thermometers, especially the Taylor, are much more accurate. It is a shame the item doesn't work better, because I liked its shape and versatility. But, those are no good if its not accurate! So - Buyer Beware! JBK

This was my second one of these. The first I had to return to Amazon since it would not turn on, even though I had replaced the battery. The second worked fine for 2 batches of beer, and then right in the middle of triple decoction mash, the thing freaks out and now it displays 134.7 as the ambient temp...So I changed the battery again. Still says it is hotter than the daytime high in the Sahara. I wrote Thomas Scientific in hopes that they could rectify, so we'll see. Maybe 3rd time will be a charm?

I needed a good waterproof thermometer that wouldn't die on me after first use, and I found it. Slightly expensive for what it is, but I'm glad i picked it up and I'll continue to use it.My only complaint would be the tiny display, which can be tough to read under the wrong lighting. That, and the fact that the mini suction cup on the probe seemed to melt or warp in boiling water after first use, making it unusable. And if there was one other complaint, it would be of its lack of features. For the price, it really doesn't do much of anything but display a temperature. No timer, no high or low temperature warning sound, just the simple temperature display.
