CO2 level transmitter with two output relays.
The CO2 measurement is based on a 2-source, 2-beam process. CO2 measurement with long-term stability is guaranteed thanks to the proven non-dispersive infrared (NDIR) CO2 measurement cell. The unique patented auto-calibration procedure compensates for aging of the infrared source and guarantees high reliability, long term stability and eliminates the need of periodical recalibration in the field.
The device is supplied with CO2 probe with 1m cable. Cable lengths 2, 4 or 10 meters available optionally.
Included in delivery:
- H5521 sensor
- Traceable calibration certificate
- Quick start manual
- Technical support at discussion forum
Transmitter is also equipped with three alarm LEDs:
Green LED shines - CO2 concentration 0 to 1000 ppm
Yellow LED shines - CO2 concentration 1001 to 1200 ppm
Red LED shines - CO2 concentration 1201 ppm and more
