AcuRite Digital Humidity Gauge

Dust mites and molds, the two most common indoor allergens, both require humid, warm environments for growth. This indoor/outdoor Acu-Rite digital humidity gauge allows you to accurately monitor the humidity in your home so that you can keep it at a healthy level. With a large, easy-to-read display, this AcuRite provides you up to the second readings on temperature and humidity. With a 10' external sensor probe, you can also monitor outdoor temperatures or the tempature wherever you place the probe. The unit can be mounted to the wall or stand on its own as a display stand allows the gauge to sit upright. A backlight can be turned on to illuminate the screen under lowlight conditions, while the push of a button can quickly show you the current time.

For the best control of mold and dust mites, we recommend maintaining a relative humidity of 40 to 50 percent for allergy sufferers. This impressive yet affordable Acu-Rite humidity gauge includes a submersible, weather-resistant probe for extreme outdoor weather monitoring and requires one "AAA" battery (not included).

  • Temperature Range (Main Unit) - 32°F to 122°F; Probe: -58°F to 158°F
  • Dimensions - W 2.75" x H 4.5" x D 0.5"
  • Humidity Range - 16% to 98% Relative Humidity

Our new dehumidifier is fabulous. This is the second week we have had it hooked up. It is quiet and does a tremendous job. Our basement was at 65 percent humidity. Now, it is 47 percent, and the smell is completely gone. Thank you so very much!

Excellent gauge to watch humidity levels in all areas of home. Portable to each room and is quite accurate. I don't use the outside temp as I am not interested in that. Just inside temp and humidity levels.

This gauge is easy to use and affordable. I recommend it to anyone curious about the humidity levels. I bought it for my apartment because I don't have a vent in my bathroom and also because I live by the ocean and love to have my windows open.

Customer Q & A

Q1: I'm using this on the race track to measure humidity. Will it work?
A: Yes. It's battery powered so it will work anywhere so long as the sensor part is exposed to open air.

Q2: How long does it take for this product to take an accurate humidity reading? I plan to take one from home to home for readings I have a home watch business and this would be the best way I can think of to assure the combiation A/C/humidifier is operating correctly.

A: Not long. Typically it will readjust to the correct readings in just a couple short minutes. It only needs a small amount of time to take readings of current conditions.

Q3: Where is this device made? ie. country of origin

A: China
