Indoor Hygrometer

Maintaining an improper humidity level indoors can cause a lot more than structural damage to the building and decay furniture pieces as it can impact your health negatively as well. No matter if we are talking about high or low humidity levels, whatever exceeds the normal directly threatens the integrity of your health. Thus, measuring relative humidity is essential as you won’t only be aware of environmental conditions at all times, but you will know what course of action needs to be taken in order to normalize indoor moisture.

Hygrometers Reviews

AcuRite 00613

Compact and boasting an intuitive use as all the information you are interested in is shown on its easy to read display, this AcuRite entry is perfect for use in any indoor space. It requires one AA battery to run, and the battery is sure to not deplete too fast as the power rating of the device is only 20 watts. With the simple touch of a button, it allows you to toggle between degrees Celsius and degrees Fahrenheit as you prefer. To be able to rely on the readings it provides, make sure you don’t place it in the proximity of a vent, heat source, or in direct sunlight, as the sensitive sensors it features will provide wrong results as they will be influenced by the environmental factors. As long as a proper placement is ensured, its accuracy and reliability are unmatchable.

Humidity Monitoring

Obviously, the reason why you are interested in it, to begin with, is that you want to know what the humidity level indoors is, monitoring this environmental factor. As it can display moisture readouts as long as relative humidity levels range from 16 to 98%, no matter how dry or damp the air gets, the device will provide a reliable reading. Of course, in order to offer this reliability, it delivers an enhanced accuracy of +/- 3% – this accuracy applies when relative humidity ranges from 30% to 80%. When dampness levels exceed or drop below the aforementioned range, its accuracy is slightly affected, shifting to +/- 4%. Another great feature is the fact that it displays whether the current dampness level is high, low, or ideal in terms of comfort for the human body.

Temperature Monitoring

It will be a lot easier for you to know what is the temperature you must maintain indoors to feel comfortable if you can monitor it and test different scenarios. As the device is even capable of providing temperature readings, it serves you even further in your quest for perfecting the conditions of your habitat. As aforementioned, it displays temperature either in degrees Fahrenheit or Celsius so that you pick what the setting you are accustomed to. It can display temperature readouts within a range of 32 to 122 degrees Fahrenheit or 0 to 50 degrees Celsius. When it comes to accuracy, the +/- 2 degrees Fahrenheit margin of error should be more than enough to convince you of its dependability.

Mention Worthy Details

  • Measurement frequency is every 15 seconds to ensure an updated overlook on dampness indoors.
  • Displays lowest and highest humidity and temperature records over the past 24-36 hours.
  • Allows you to select between degrees Fahrenheit or degrees Celsius with the simple press of a button.

Design

It measures 3 inches in height, 2.5 inches in width, and 1.3 inches in depth, perfectly fitting in every room of your home as it doesn’t take up much space. This incredibly compact design makes it portable as well, so if you want to take it to the office or when you are on the go to track environmental conditions, it won’t be troublesome at all. Another design element worth mentioning is the fact that it can be mounted in 3 different ways – on the wall using the mounting clip, against the refrigerator due to its magnetic back, or on the tabletop as it will sit against the fold-out stand that it features.
What We Like

  • Displays daily high and low records
  • Humidity level icon indicates whether moisture is at a high, low, or ideal comfort level
