CO2 Monitor / Controllers 

Both the CDMC-6 and the CDMC-7 feature the Carbon Dioxide Digital Sequencer (CDDS-2) with a single patch cord and is an automatic and programmable CO2 control system. The CDMC-7 utilizes the CDM-7001 monitor that is battery powered and portable so you can perform instantaneous spot checks of CO2 levels in different areas. The CDMC-6 has all the same quality features of the CDMC-7 except it utilizes the CDM-6000 monitor which doesn't have the hand-held portability of the CDM-7001. With these units you can accurately control your CO2 levels to within 10 PPM (parts per million). Both these great units feature 0 to 2000 PPM read out with a linear output signal which can be used to interface with a computer or other interface device.

These Green Air Products systems are a breakthrough in CO2 detection and control. The CDMC-6 system is designed to sample the air and learn the characteristic of your space, then make adjustments as necessary to ensure a constant level of CO2. The CDM-6000 monitor employs a passive infrared sensor which samples the air once every second and then sends the sample data to the CDDS-2 sequencer. The CDDS-2 then activates or deactivates your CO2 enrichment or venting (exhaust) equipment to maintain desired CO2 PPM. The CDDS-2 uses a sophisticated adaptive algorithm or "Overshoot Protection Logic" to learn the dynamics of the space being controlled. This allows the systems to avoid dramatic overshoots inherent to set point controllers or timed CO2 enrichment. These learned parameters are stored in the memory, even when the 'POWER' is off, or until you reset the unit.

The CDMC-6 system offers a large LCD screen displaying the current CO2 levels in PPM. Set your desired CO2 level, 'Hysteresis' and 'Elevation' to maintain precise levels without guesswork. The CDMC-6 system can be used for enriching or venting CO2 and incorporates a photosensor to defeat CO2 during dark periods (night).

The CDMC-7 system functions like the CDMC-6 for CO2 enrichment or ventilation, but offers the added features of a portable monitor in the CDM-7001 with dual beam absorption infrared technology and a LCD display that shows CO2 PPM and real time temperature. The CDM-7001 monitor is also equipped with a computer interface to download CO2 history. Recorded data can be graphed and printed using a Windows based VG graphing software (not included).

These monitor/controllers can control either CO2 Generators or CO2 Injection Systems and will keep CO2 levels to an optimum level for accelerated plant development.
