With Display LCD
The instrument measures: CO2
The Sensor measures: CO2
Cable Length: 1 meter
Power Supply: 9-30 Vdc
Sensor IP Rating IP65

The CO2 carbon dioxide concentration transmitter with 4-20mA or 0-10Vdc outputs is built into a durable waterproof housing.
The output range is user adjustable.
The large two-line LCD screen is a bonus. The screen can be turned off.

The device comes with a CO2 probe, with a 1 m cable. Cable lengths of 2 or 4 meters available optionally.

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 at:

- Building HVAC management
- Climate technology
- Schools, universities
- Meeting rooms, hospitals, cinemas, theatres
- Weather stations

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

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 values are converted to 4-20mA current output.

Output is 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 T5141, output 0 to 10000ppm
