The Essentials Digital 2-Way Thermometer/Min Max Meter simultaneously displays both the humidity and temperature levels in the grow room, the min-max also indicates and records the minimum and maximum temperature and humidity level achieved.

The Min-Max hygrometer measures humidity and temperature over a range of 0 to 50°C and 10% to 99% humidity.

Understanding grow room humidity and temperature levels will allow growers to make the necessary adjustment to maintain optimal conditions.

The Min-Max can be freestanding or hung by the hook from a shelf. This unit is great for monitoring the air environment in your grow-space.
