BETA-8
The BETA-8 CO2 controller offers a precision NDIR CO2 sensor/controller in an affordable, easy-to-use package. The BETA-8 is equipped with a high-quality remote CO2 sensor (with a 16-foot cable) and a built-in photocell to automatically activate your supplemental CO2 system to maintain CO2 PPM levels only during daylight hours. The BETA-8 also features an adjustable deadband and a min-max recall. It also has a 'fuzzy logic' function that will more accurately control compressed CO2 systems. The CO2 sensor can be easily recalibrated and will continue to operate accurately for many years.
