Series 900 – Fixed Indoor Air Quality Monitor

The Series 900 Fixed Indoor Air Quality Monitor is a flexible monitor compatible with a wide range of gas sensors suited for indoor applications.  The monitor can also be configured with a temperature and humidity sensor, if required.  It is designed to measure and control gas concentrations and communicate to a variety of hardware systems.  The indoor air quality meter can operate in three ways:

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

2. As a gas 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.

3. 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.
