Nice little tool

"I use this device both at home and for work. I think the important thing for potential customers to realize is that this is not like an instant read thermometer. If you are going from a hot car to a conditioned space you need to give the HygroBug some time to acclimate. For work I put it in the space I want to monitor and come back to it after 10-15 min. I like the min/max per session option. Hard to beat for $50, very portable, great battery life, and NIST certified."

"Works great and accurate! Love being able to see the true temp and humidity readings. I used these because temps on my thermostats were wrong so I used these to manually correct the thermostat."

Works great. Size is OK.

"Works great. Size is OK. For my purposes (3D printer dry boxes) these units could just a bit thinner and shorter, but I made them fit well. Nice to have an easy to read precision device."

Aaron A. (4/5)

Excellent product

"I’m using it in my wine cellar area and the temp combined with humidity is perfect. Love the size and the display screen with the light. Highly recommend!"

Dana S. (5/5)

Disappointed

"Typically ThermoWorks products are great. This HygroBug is an exception. It appears measuring Humidity is not ThermoWorks expertise. The accuracy of the humidity was suspected to be inaccurate. A humidity salt test was done. The results were the HygroBug was off 4%. Unfortunately, the meter does not have an accuracy adjustment."

A great tool for incubators!

"I can honestly say that this has been one of the best purchases I've made in a long time. I use it in my incubators to give accurate temperature and humidity readings. My hatch rates have improved, and I have confidence that my incubators are functioning. I highly recommend."

Works as planned
