SDC-Q1 - Duct mount

Smart Air Quality (VOC) transmitter duct mount

Reliable evaluation of duct air quality: The sensing element used is a MOS (metal oxide semiconductor) based gas sensor
component. It is specifically designed for a broad detection of reducing gases such as VOCs (volatile organic compounds)
associated with bad air quality (cigarette smoke, solvents and cleaning agents, emissions, etc.).

The microprocessor samples the air quality once per second. It calculates an averaging signal over a preset number of
samples and generates the output signal. The analog output signal range may be customized by jumpers and can also be set by using the optional internal or external display and programming module OPC-S or OPA-S.

Applications

Demand based ventilation for homes and offices based on measurement of the VOC concentration (air quality)
Recording of minimum and maximum limits for critical environments
Direct control of extraction fan
