The Sensor measures: Temp. / Rel. Humidity / CO2

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.

Measured temperature and relative humidity values are also converted to other humidity interpretation - dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy. Degrees Celsius and Fahrenheit are user selectable. 

APPLICATIONS - measuring of temperature, humidity and CO2 level at:

  • building HVAC management
  • climate technology
  • schools, universities
  • meeting rooms, hospitals, cinemas, theatres
  • weather stations

Transmitter is equipped with two relay outputs for alarm indication or control of external devices. Each relay can be assigned to any measured or computed value. For each relay setting of delay, hysteresis, audible alarm is enabled.
Parameters are easy adjustable from regulator keyboard or from the computer.

Transmitter contains a microprocessor based control circuitry in a durable plastic case with connection terminals and temperature an relative humidity sensors in a filter with stainless steel mesh. The CO2 concentration sensor is built inside the case.

Large dual line LCD is an advantage. Display is possible to switch off. Computerized design ensures maximum long term stability and failure indication.

State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation. Transmitter is designed for use in non-aggressive environment.
