RH SPOT® is a thermo-hygrometer that shows you whether an environment is actually stable by tracking both temperature and humidity together. Temperature alone doesn’t tell the whole story. In places like fridges, wine cellars, cheese caves, proofing boxes, and greenhouses, humidity matters just as much as temperature. When moisture levels drift, food dries out, mold grows, dough stalls, and wood, paper, and cork degrade. 

With a reading range from –13 to 122°F, ±1.8°F temperature accuracy, and ±2% RH accuracy in the range that matters most, RH SPOT delivers dependable data instead of guesswork. A large, auto-rotating display shows temperature and humidity at a glance, while max and min tracking reveal how both change over time. Built with an IP65 water-resistant housing, a powerful magnetic base, and an included mounting plate, RH SPOT stays in place in damp, cold, and enclosed spaces. 

  • See What Temperature Alone Can’t: Track both temperature and humidity so you know whether dough, wine, cheese, and stored food and materials are safe.
  • Built for Damp, Cold, and Enclosed Spaces: An IP65 water-resistant body handles condensation, spills, and humid storage areas.
  • Runs for Months Without Attention: A smart, light-activated display turns on when you need it and conserves power when you don’t — delivering up to 5,000 hours of battery life on a single CR2032 battery.
  • Verified for Accuracy: Every RH SPOT includes a NIST-traceable calibration certificate for both temperature and humidity.
  • Catch Drift Before It Causes Damage: Max and min memory shows the highest and lowest temperature and humidity so you can spot overnight swings and slow changes.
  • Read It Anywhere You Mount It: A large, auto-rotating display stays legible on shelves, walls, and ceilings.
  • Put RH SPOT Exactly Where It Matters: A powerful magnet and included mounting plate secure it in the precise “spot” you need to measure.

Reviews

Love it!

"Love it!"

Ernest P. (5/5)

Inconsistent waste of money

"I bought 3 identical Rh spot devices for use in my house and small greenhouse. They all show different temperatures and very different humidity readings even when placed right beside each other. I expected that since these are a lot more expensive than typical Amazon units that they would work well. They don't. They are a waste of money."

James C. (1/5)

Excellent thermometer and humidity sensor

"We wanted another thermometer for our freezer - and this model was on sale. As with all ThermoWorks products the quality is excellent."

Abby F. (5/5)

RH Spot

"I use it in my fridge. Works great!"

Kathleen B. (5/5)

Just buy it. You'll be glad you did.

"Love it. Temperature and humidity in an easy-to-read, no nonsense package. I like that it can be read if stuck on the wall or ceiling. The magnet is strong, not wimpy. I also like the display alternating between temperature and humidity WITHOUT going through a series of commands or pressing a bunch of buttons. I am totally happy with it."

Mike (5/5)

. . . and now I know.

"We did not have a thermometer of any type in the house. Our home heating is not indexed to temperature numbers either. We never knew how hot any room was, what the temperature on the porch was. . . nothing. But we got these and now I know. They have functioned perfectly with one strange exception. . . I was watching TV in a dark room and there was a flash to my left. I looked over and the PH Spot had turned itself on and illuminated itself. It just did it once. Ghost."

Robert Y. (4/5)

Great product with thermoworks accuracy

"Great product. Does exactly what I needed, and with ThermoWorks accuracy I now know that my fridge works well and where its cold, hot, humid, and dry spots are."

Amir H. (5/5)

Thermoworks Temperature & Humidity Everywhere Thermometer

"This small, cost-effective device is employed to monitor humidity in my home where we previously suffered a mold infestation in the living and dining rooms. This mold outbreak compelled a thorough abatement effort, which we would like to prevent, and is being accomplished with both installation of ""so-called mini-splits"" and a separated humidity gage. So far, so good. Thanks!"

Jack C. (5/5)

Small but easily readable.

"Love these and wish I had purchased more while they were on sale! Because of humidity problems in our house I've put these in several rooms to monitor the humidity after installing a whole house dehumidifier. These are more accurate than the monitor in our thermostats."

Andrea A. (5/5)

I wish I could turn

"I wish I could turn off humidity. Have to pick up to read. Ex: 68 and 59."
