Remote CO2 Concentration Transmitter, Ethernet Interface, 2 Relay Outputs
H5521
CO2 level transmitter with two output relays.
CO2 measurement is based on a dual source, dual beam process. Long-term stability of CO2 measurements is ensured by the proven non-dispersive infrared (NDIR) CO2 measurement unit. A unique patented auto-calibration procedure ensures high reliability, long-term stability by compensating for the aging of the IR source and eliminating the need for periodic recalibration in the field.
The device is equipped with a CO2 probe with 1 meter cable. Optional cable lengths of 2 or 4 meters are available.
CO2 concentration is shown on the display or signaled by colored LEDs.
Measurement data can be processed and analyzed in the following ways:
Online Processing on COMET Cloud
