SMT-IAQ3 Indoor Air Quality  sensor features a  large backlit LCD that not only indicates the current indoor air quality levels for each of the three sensor, the backlight can also be programmed to change from green, to amber to red as indoor conditions worsen should it be desired. To provide a audible warning of poor indoor air quality an internal beeper can be programmed to sound at the alarm threshold.

All outputs of the SMT-IAQ3 can be fully adjusted to match your preferred measurement range and required output voltages. This permits you to connect a fresh air damper, a fan or VSD directly to the SMT-IAQ3 without the need to set up external scaling.
