Model M1 Toxic / Combustible Gas Monitor from Global Detection Systems Corp.

The GDS Corp. Model M1 Non-Intrusive Gas Monitor detects combustibles, many toxics or oxygen gas concentrations and displays them in engineering units on a 3½ digit LCD readout. Sensors plug into a universal sensor head and are easy to replace. Modbus® RS-485, 3 alarm levels and isolated 4-20mA options allow the M1 to solve most application interface requirements.

Nonintrusive magnetic zero/span controls allow one-man calibration without opening the enclosure. Nonvolatile memory retains all calibration values during power loss. Any "Power On" or "CAL Exit" is followed by a 1-minute delay where the 4-20mA output is locked at 4mA to prevent false alarm trips.
