Comet H5021 CO2 Concentration Transmitter with Two Relay Outputs

The CO2 – carbon dioxide level is recently regarded as an important parameter that substantially determines the quality of the interior climate. Especially in buildings where many people gather, such meeting rooms, hospitals, schools, cinemas, theatres and care centres. With the help of CO2 sensor engineers, technical advisors, environmental experts and health specialists can optimize the ventilation for creation of a healthy interior climate.

Method of CO2 sensor multipoint calibration leads to an excellent accuracy measurements of CO2 in the entire of operating temperature range. With this sensor is the device able to meet the demanding requirements for outdoor use. The measurement principle is based on the NDIR principle with dual wavelength, which automatically compensates for aging of the sensor. The sensor is resistant against the pollution and provides maintenance-free operation and excellent long-term stability.

Programmable regulators with relay outputs are designed to measure temperature and relative humidity of air, to measure concentration of CO2 in air, to signal alarms and control of external devices. Regulators can be used in a chemical non-aggressive environment.

The CO2 concentration is measured using the dual wavelength NDIR sensor with the multipoint calibration. This principle compensates aging of the sensing elements and offers maintenance free operation and outstanding long term stability.

The function of two output relays can be set from regulator keyboard (or from computer) and using the jumpers. Each relay can be assigned to one of measured or computed value (dew point temperature, absolute humidity, specific humidity mixing ratio and specific enthalpy). Setting of delay, hysteresis, audible alarm is enabled for each relay. Measured and calculated values are displayed on a two-line display. The visual indication of the CO2 concentration is provided by three LEDs to the left side of the display. Using TSensor software can be all regulator parameters set. To connect to PC is used USB adapter SP003.
