VOC Gas Monitoring System


The MS1100 is an on-line VOC gas monitoring system which provides low level measurements of VOCs in air.

It is designed to provide:

  • Chimney stack emission monitoring
  • Environmental monitoring with high sensitivity
  • Drain Monitoring
  • Flammable gas detection


Principle of Operation

The MS1100 utilises an array of sensors to detect volatile gases and provides a highly reliable measurement system with very low maintenance requirements.


Control and Monitoring Options

The instrument is housed in a robust steel enclosure and can be powered from either 90 – 240V AC or 24V DC supplies.
Various communications options are available including 4 – 20mA, Profibus and Modbus.
This monitor is also available as a standalone unit without sampling system.
An ATEX compliant version of this system is available on request.
