Description Trol BETA8 Digital CO2 PPM Controller BETA-8 Digital CO2 PPM Controller offers a practical and affordable way to control your CO2 injection devices (CO2 regulator & generator). In short, plug in your co2 device (eg a burner or gas regulator) into this device; the included sensor then measures the amount of CO2, > sends it back to the Beta-8 unit > Beta-8 sends a signal (according to the set programme) to open/close the device that controls the Co2. The BETA-8 features a high-quality remote CO2 sensor (with 16ft 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 has an adjustable deadband and min-max recall. It also has a ‘fuzzy-logic’ feature which will more accurately control compressed CO2 systems. The CO2 sensor can be easily re-calibrated and will continue to operate accurately for many years.
