T8248 CO2 concentration and temperature transmitter with 0-10V outputs, built-in sensors

code: T8248
CO2 - carbon dioxide level and temperature sensor.

carbon dioxideCO2 concentration and temperature transmitter with two 0-10V outputs is specially designed for use in exacting interiors in building energy management and HVAC systems. It designed for easy installation on ordinary KU68 wiring boxes for household switches and sockets.
Large dual line LCD is possible to switch off.
Computerized design ensures long term stability and fail indication. Transmitter is designed for use in non-aggressive environment.

Included in delivery:

  • Traceable calibration certificate
  • Quick start manual
  • Free program TSensor for configuring of the transmitter is ready to Download


Transmitter is also equipped with an alarm LED:

LED shines green - CO2 concentration 0 to 1000 ppm

LED shines yellow - CO2 concentration 1001 to 1200 ppm

LED shines red - CO2 concentration 1201 ppm and more

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.



APPLICATIONS - measuring of CO2 level and temperature at:

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

Transmitter contains a microprocessor based control circuitry in an ABS plastic case with connection terminals.

The CO2 concentration and temperature sensors are 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.

Measured CO2 concentration and temperature values are converted to 0-10V voltage outputs.

Outputs are adjusted to maximum range from the manufacturer.
To adjust other range by the user buying of SP003 cable is necessary - see Optional accessory.
Free configuration program TSensor for transmitter adjustment is ready to download anytime.

If different adjustment of output range is required, please specify required range in the order. Adjustment is free of charge.

Ordering example: Transmitter T8248, outputs 0 to 2000ppm and 0 to 50°C
