The Multi Gas Analyzer uses Infrared technology for the detection of bipolar gases such as carbon dioxide and methane. Electrochemical cells are used for toxic gases and oxygen. The sequencer in the Multi Gas Analyzer presents each gas sample in turn from every sample point location to the analyzer. The previous sample is fully flushed out from the analyzer before receiving the next sample, this eliminates false alarms being initiated from an incorrect sample point. The sampling time from each point can be set, by the user, between 1 and 120 minutes. 

The Multi Gas Analyzer has an auto-calibration system as standard. The reliability and integrity of the system is ensured with this user friendly, flexible calibration routine. The auto-calibration frequency can be set by the user to calibrate every hour up to a maximum of every 168 hours (once a week). Once the calibration routine is initiated, a sample of zero gas (usually nitrogen) is introduced and used to set the zero limits. 

A known concentration of calibration gas is then presented to the analyzer, this sets the calibration limits. The system then returns to normal operation. An end of line filter unit is used to prevent contamination from water or dust. For severe conditions, where heavy particulate contamination is possible, special heavy duty filters can be supplied. 

All sample data is stored on the system hard disk drive and can be downloaded for archiving or for exporting to a spreadsheet for analysis. 

- Common and individual low and high alarm relays can be provided. 

- Common Fault / Flow Fail alarm relays. 

- Standard 3PCO contacts rated at 10A, 250Vac / 24Vdc non inductive load. 

In addition, the Multi Gas Analyzer can be configured to operate ancillary equipment, e.g. Audible / Visual alarm units.
