Holmes HHG175 Digital Hygrometer

This model has been discontinued. As an alternative, we recommend the Honeywell E-10 Enviracaire HealthCheck Humidity Monitor.

    Features and Benefits:
  • Helps monitor your optimal comfort level
  • Reads indoor humidity level and temperature
  • Easy to read, large digital display

    Direction for Use:

  • Requires one AAA Alkaline Battery (included)
  • Place your monitor on a desk or bureau away from windows, heaters or humidifiers. Adjust your home thermostat or heater to meet your comfort level.
  • A relative humidity level of 45% to 50% at temperatures from 68°F to 72°F is considered optimal. If the humidity level reads below 30%, then you should increase your humidity level by using a humidifier.
  • If your humidity level exceeds 60% or if condensation appears on the windows, then turn off your humidifier.
  • If your humidity level consistently reads above 60% humidity, then you need to decrease the humidity in the room by using a dehumidifier or air conditioner.


We have a large selection of humidifiers and air purifiers to keep you healthy this winter!
