DESCRIPTION

· The H5521 CO2 level transmitter features an Ethernet interface and two output relays.

· It utilizes a 2-source, 2-beam process for CO2 measurement, ensuring long-term stability with a non-dispersive infrared (NDIR) CO2 measurement cell.

· The device includes a patented auto-calibration procedure to maintain high reliability and eliminate the need for periodic recalibration.

· It comes with a CO2 probe with a 1m cable, with optional lengths of 2 or 4 meters.

· CO2 concentration is displayed and indicated by a color LED.

· Data processing and analysis are supported online via COMET Cloud and COMET Database software, with integration into third-party systems.
