Trolmaster 4-in-1 sensor for hydro-x pro and hydro-x plus mbs-pro the mbs-pro is an integrated environmental sensor that houses precision measurements for air temperature, relative humidity, co concentration ppm , and ambient light in a single, compact unit. It’s fully compatible with both hydro-x pro and hydro-x plus systems. Enclosed in a newly designed, water-resistant, injection-moulded plastic housing, the mbs-pro can be distributed throughout your cultivation space to capture spot readings from multiple locations up to 50 sensors on a hydro-x pro network . You can view each sensor’s data individually or combine them via averaging to control specific zones assign any sensor to drive a particular device for targeted environmental management.
