Series 900 – Fixed VOC Monitor

Series 900 – Fixed VOC Monitor

The Series 900 Fixed VOC Monitor is a flexible monitor designed to measure and control concentrations of volatile organic compounds (VOCs) in air. Compatible with four ranges of swappable VOC sensor heads. Suitable for use on a range of projects, including indoor air quality monitoring, health and safety monitoring, and real-time networking.

Compatible with four ranges of VOC sensor heads, plus temperature and humidity

Flexible outputs enable use as a relay controller, gas transmitter, or monitoring network

Lightweight, discrete, and easily wall mountable

Product overview

The Series 900 enables flexible use due to a wide range of outputs and configurations. The monitor can operate in three ways:

  • As a relay controller with user configured set points to control an external device such as an ozone generator or initiate an alarm.

  • As a VOC transmitter via the 4-20 mA output which allows connection to a PLC or current sensing device to provide gas concentration information for applications such as health and safety monitoring.

  • As a monitoring network via the RS485 digital output to enable gas monitoring at several indoor locations with information being logged to a central point.

The Series 900 is lightweight, discrete, and easily wall mountable. It requires a 12V power supply, which is user configurated to allow flexibility in installed locations.

There is also free to download configuration and networking software available under the downloads tab. The configuration software allows for quick and easy configuration of the alarm and control set points. The networking software can be used to log data from a network of monitors to a single PC.

For more information around measuring ozone with our ozone monitors, please view our general guidelines on measuring ozone and factors that can affect ozone measurement.
