Maintaining a CO2 level between 1000 and 1500 PPM is essential for most plants. CO2 can be increased by either using compressed CO2 or or a CO2 generator. How do you know if you have the necessary level? Eliminate the guesswork. The sentinel CPPM-1 allows you to control CO2 with Parts Per Million accuracy. One touch calibration of the CO2 sensor. Simple push buttons to enter desired PPM settings and display the current CO2 PPM readings. Easy to read LED display. Can be operated in "Fuzzy Logic" mode for compressed CO2 or On/Off for CO2 generators. Optional 12 volt DC adapter allows for coordination with other controllers like the EVC-2. CO2 receptacle to connect CO2 generator or 120 volt compressed CO2 solenoid / regulator assembly. The supplied 12 volt power supply connects to any temperature controller so that the CO2 devise will be disabled when the fan is operating. Remote CO2 and light level sensor can be positioned inside the area and the CPPM-1 outside of the area. Remote Sensor comes with 15 ft cable.
