Sentinel CPPM-1 CO2 PPM Controller
Maintaining a CO2 level between 1000 and 1500 PPM is essential for most plants. The CPPM-1 controls your growing area's carbon-dioxide levels with part-per-million (PPM) accuracy.
The Sentinel CPPM-1 CO2 PPM Controller uses a CO2 sensor that is extremely precise and features a ten-year life expectancy. This remote CO2 and light level sensor can be positioned inside the growing area with the CPPM-1 unit positioned outside of the grow room. It comes with a 16' cord, but can be extended up to 100'.
As you would expect from Sentinel, the LED display on the CPPM-1 is easy to read and provides simple pushbuttons to enter the desired PPM settings and to display the current CO2 PPM reading.
The CPPM-1 can also be connected to other controllers so that the CO2 is disabled (useful when operating exhaust fans), or it can be operated in Fuzzy-logic mode when using compressed CO2, or ON-OFF when using CO2 generators.
