It is designed to monitor VOC gases in industrial processes and applications as well as in environmental monitoring applications. The instrument senses gases or volatiles providing a measurement system with very low maintenance requirements. Taking a measurement every 2 seconds, the MS1800 is accurate at concentrations from 1 to 500 ppm, dependent upon the target gas, and its wide dynamic range allows it to be used in a variety of environments.

A user-programmable concentration alarm threshold can be set, connecting to a relay output and an indicator on the front panel. This allows connection to other peripheral equipment such as isolation valves, pumps, samplers or audio-visual alarms.

A 4–20 mA output is available for connection to a PLC or SCADA system and the MS1800 can operate from 90–240 V AC or 12 V DC power supplies.
