SM70 Fixed Indoor Air Quality Monitor
A Low Cost Feature Packed Ozone and VOC Monitor.
SKU
SM70
The SM70 Fixed Gas Monitor is a low cost feature-packed gas monitor designed for a wide range of indoor and industrial applications. The monitor comes with an integrated LCD display, RS232 and 0-5V outputs and audible alarm, which can be configured to a user defined set point. It also comes with a 12VDC power supply that plugs directly into the monitor and mains power allowing for easy set up and installation.
The gas sensor board is factory set to one of three optional firmware settings to control the relay and alarm functionality:
- Alarm above – The relay is programmed to energise above the selected set point. Typical applications include health and safety alarm warning systems and switching external equipment on and off.
- Alarm below – The relay is programmed to energise below the selected set point. Typical applications include fail safe warning systems and control of an ozone generator.
- Control 10% – The relay is programmed to open and close ±10% within a user selected control band. Typical applications include maintaining a specific gas concentration between user defined levels via the control of an external device e.g. an ozone generator.
