H5521 | Ethernet & Relay Outputs

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 or 4 meters available optionally.

The CO2 concentration is shown on the display or signaled by a color LED.
