DPM72 CO2 - Carbon Dioxide Analyser

Carbon Dioxide Analyser DPM72 CO2 is a self contained Carbon Dioxide analyser  manufactured by SATS


The DPM72 CO2 is a self contained Carbon Dioxide analyser housed in a 3U x 42HP sub-rack case that fits into a standard 19” x 3U sub-rack frame where it occupies ½ of the rack width. The analyser can also be panel mounted using an adaptor plate.

The DPM72 CO2 uses a barometric pressure compensated carbon dioxide sensor. The sensor outputs a signal that is proportional to the partial pressure of Carbon Dioxide; this signal is scaled and displayed in parts per million (ppm) Carbon Dioxide on the high visibility LED display.

Both calibration and alarm settings are adjusted using the keypad accessible menus. All the settings are stored in non-volatile memory. A hardware keypad disable function can be used to protect both the calibration and alarm settings from tampering by unauthorised personnel.

Optional analogue or RS485 serial data outputs are available to drive chart recorders or to connect to more sophisticated data monitoring packages such as the SAT Systems “Scan” software package.
