CO2 concentration transmitter with 4-20mA output T5140 is built in a durable case. Output range is user adjustable. Large dual line LCD is an advantage. Display is possible to switch off.

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.

Included in delivery:

  • T5140 sensor
  • Traceable calibration certificate
  • Quick start manual
  • Free program TSensor for configuring of the transmitter

Transmitter is also equipped with an alarm LED:

  • Green LED shines - CO2 concentration 0 to 1000 ppm
  • Yellow LED shines - CO2 concentration 1001 to 1400 ppm
  • Red LED shines - CO2 concentration 1401 ppm and more
