BETA-6 Digital Day/Night Humidity Controller

The TrolMaster BETA-6 is a standalone digital day/night humidity controller for grow rooms and tents. It uses a precision humidity sensor on a 16 ft (4.8 m) remote probe to read conditions at canopy level, and a built-in photocell to switch automatically between separate day and night setpoints. Adjustable 20–90% RH range with a 5% deadband helps avoid short cycling. Simply plug a humidifier or dehumidifier into the controlled outlet and set targets on the clear digital display. The unit operates on 120 VAC, includes a 1.8 m power cord, and ships with the remote humidity sensor. Suitable for stabilizing humidity in propagation, veg, flower, and drying spaces where a single 120 V device needs simple on/off control.
