Gasmax - Model EC -Single Channel Toxic Gas Monitor

The highly visible display shows calibrated engineering values, bar-graph data, 30-minute trend and setup information. An internal real-time clock time-stamps calibration and alarm events for later review. Front panel flashing LEDs continuously indicate alarm conditions.

Operator interface is a menu-driven magnetic keypad, allowing complete setup and calibration without hazardous area declassification. There are no potentiometers and all adjustments are performed through the magnetic keypad interface.

The GASMAX / EC maintains a record of sensor calibration data that provides an estimate of sensor life remaining.  During each post-calibration purge delay, the GASMAX / EC can be programmed to transmit this data on the 4-20mA output.  Controllers such as the C1 Protector can display and communicate this data to a distributed control system or HMI such as the ProtectorHMI Data Visualization & Logging Software.

Locally connected Smart Sensors enhance this capability by maintaining their own electronic record of serial number, born-on date, initial calibration values, engineering units and other data, ensuring the most accurate measurement and alarming capability available today.
