BETA-8 Digital CO2 PPM Controller

The TrolMaster BETA-8 is a standalone digital CO2 PPM controller that maintains a user-set CO2 level in grow spaces. It uses a remote NDIR CO2 sensor (16 ft cable) and an integrated photocell that disables enrichment at night. The unit offers adjustable deadband (20–200 ppm), min/max recall, and a fuzzy‑logic mode to more precisely regulate compressed CO2 systems. It controls one CO2 device via a 120 V AC, 10 A relay and includes a 6 A/250 V fuse and 1.8 m power cord. Measurement specs include a 400–2000 ppm control range and ±50 ppm accuracy. The CO2 sensor can be user‑calibrated. Package includes the controller and sensor; do not use fuzzy‑logic mode with CO2 generators.
