TH1981 Thermometer Hygrometer is a vital tool for monitoring the air environment in two different locations. It is essential to measure and record the temperature and humidity readings of your grow space to better understand and meet your plants needs.
The Large LCD digital display base unit gives a constant readout of the time and date (with 12hr/24hr options), at the top half of the screen. The units internal temperature and humidity sensors display on the top of the lower half of the screen. The bottom of the lower half shows a readout of the temperature and humidity from it’s external wireless sensor.
The temperature can be displayed in either Celsius (C) or Fahrenheit (F). The device has a memory and can display the maximum and the minimum internal/external temperature/humidity since the unit was last reset.
How to use the TH1981 Thermometer Hygrometer:
Insert the included batteries and then place the base display in the area you'd like to measure the temperature and humidity and place the remote wireless probe outside or even in another grow-room. The device will take a little time to adjust to its new surroundings.
After a short while the Large LCD digital display will show both the time and date, your internal and external wireless remote sensors maximum, minimum and current temperature and humidity levels.
Place or mount the thermometer/hygrometer in the area where you wish to monitor the internal temperature and humidity by either pulling out the stand on the back to sit it on a flat surface or you can hang the unit on a wall from a small screw from it’s keyhole recess.
