SP Bel-Art, H-B DURAC Plus Pocket Liquid-In-Glass Laboratory Thermometer; 20 to 120F, Closed Plastic Case, Organic Liquid Fill (B60770-1300)

Although mine came in purple, this is a nice, calibrated, easy to read thermometer with a temperature range that's relevant for household use. For example, I purchased a refrigerator thermometer from Rubbermaid and used this thermometer to verify the refrigerator temperature (the Rubbermaid was +2 degrees off).The thermometer is fairly quick to read temperature and the blue liquid against the white scale (with black numbering) is easy to read, so it allows you to make a quick and accurate temperature reading.Although the actual thermometer is glass (so this isn't a good item for young children!) the thermometer comes shipped in sealed bubble wrap packet which contains a sealed plastic, vacuum formed carrier. Once you open both of these disposable items, the actual thermometer is still protected by its plastic sheath which connects to the top end of the thermometer itself so it won't fall off. As you can see from the product picture, the plastic end piece of the thermometer is blue, however what shipped to me was purple, and that plastic end piece has a loop in it to connect to a cord or to hang up with.As far as thermometers go, there's nothing overly special or "trick" about it. It's simple and functional and most importantly, calibrated, so you know the indicated temperature is correct.

Inaccurate and poorly made - waste of money. Thermometer is nonreturnable so I threw it away.

OK only as a quick read thermometer like best for quick dip in a river, lake, hot tub, pool and the like. Not good for a fridge as it changes temp as you read it. Very nice pocket clip and handy case. It seems to test pretty accurate bot changes to quickly. Did not work well for my application, otherwise I recommend it and it is as described. Very well packaged.

Solid thermometer for all of your needs; large or small, human or animal! My only wish is that they came in different colors and offered personalization. Great company! Very responsive to any needs prior to purchases!Thank you, Bel-Art!! I will be back for more!

I don't think this thermometer is made for measuring body temperature. When you put it in your mouth, the temperature changes as it should, but as soon as you take it out, the temperature immediately starts to go back down- it doesn't 'hold' the maximum reading like a normal fever thermometer does. If you're reading it for someone else, it is probably fine.

I Like electronic thermometers but always question the accuracy. Here’s something easy to take with the electronic thermometers and can easily convince myself or others of their accuracy.

I found this to be pretty accurate when measured against an accurate digital thermometer. But I used this thermometer approximately 20 times and it has now developed a bubble making it difficult to determine the temperature.
