Precision measurement
We stock two precision digital meters for measuring grow room conditions. First there is the Min-Max Combo, a compact meter that displays both grow room temperature and humidity as well as recording minimum and maximum values in oC and oF.
Next is the Digital Combo Meter, which simultaneously displays both grow room temperature and nutrient solution temperature via a 1.8m (6') sensor cord. It also records minimum and maximum temperature values and includes two temperature alarms to warn of critical conditions. Temperatures displayed in both oC and oF.
