ThermoDrop® is a keychain-sized ambient thermometer that tells you the temperature of your world — not a weather station miles away. Clip it to your keys or bag for outdoor temps, use it in a greenhouse or shed for plants, or hang it in the fridge to monitor food safety. Big, backlit digits make the temperature easy to read at a glance, even in low light.

Built to go wherever you do, ThermoDrop is waterproof to IP67; tough enough for rain, snow, and spills; and accurate to ±1.8°F. It saves high and low temperatures, rotates automatically so it’s easy to read from any angle, and runs for months on a single coin cell battery. From ski days to grocery runs to keeping tabs on the fridge at home, ThermoDrop gives you a simple, reliable read on the world around you.

Reviews

As a dog walker, I

"As a dog walker, I use this to quantify temperature safety for my clients. It’s a great little piece of gear, small enough to clip to my fanny pack."

Amanda K. (5/5)

It's great!

"I bought 2 and have compared them to other thermometers and each other, inside, outside and inside refrigerator. They seem to work really well and I like the portability, one is on my keychain."

Kevin W. (5/5)

Not accurate

"When I complained about the product the company insisted that I do their test method even though I already tested with an analog thermometer. They also insisted that there could be as much as a 15 degree temperature difference between air a few inches away from each other."

Nicholas K. (1/5)

Works as advertised

"Attached to my daily backpack and the thermometer works as advertised. It does take some time to normalize if coming from a hot area to a cooler zone."

Mike M. (5/5)

It's meh. I bought two

"It's meh. I bought two and they both seem to read about four degrees warmer than the actual temperature. The size is larger than I had expected. Some sort of illumination feature would have been nice for $25 each."

Brian T. (3/5)

Love them!

"Love them so much I got 3 more. One for my motorcycle, one for my backpack and 2 for my off-road rigs."

ERICA J. (5/5)

Awesome Little Thermometer

"Super lightweight, easy UI, highly recommended"

Riley K. (5/5)

Love it. Have carried it

"Love it. Have carried it on keychain, used it to check temp of fridge, brought it camping . . . Never realized how often I’d use it. Made very well."

Chad A. (5/5)

Not accurate

"I have been using this outdoors since receiving it and reads warmer by 10 degrees. Tried keeping it shaded same thing."

Richard E. (1/5)

Great thermometer for hiking and camping.

"Bought two of these just to have a spare or use elsewhere. Quite surprised at how quick it adjust between different temp zones. I like that it reads either right side up or upside down. So far, I've been impressed. I got one in yellow so it was easy to find and one in purple because, well I just like purple."
