Sentinel CPPM 1 CO2 Controller with Integrated Photocell

The CPPM-1 controls your carbon dioxide levels with part-per-million accuracy. It uses a C02 sensor that is extremely accurate and features a ten-year life expectancy. Our combination C02 & light level sensor is housed in a separate remote sensor enclosure that can be located up to 100 ft from the controller. The CPPM-1 can also be connected to other controllers so that the C02 is disabled (useful when operating exhaust fans). It can be operated in fuzzy-logic mode (for compressed C02), or on-off (for C02 generators).
