Integrated VOC Sensor Module | Telaire MiCS-VZ-89TE

Telaire MiCS-VZ-89TE VOC Integrated Sensor Board

The Telaire MiCS-VZ-89TE Integrated Sensor Module combines state-of-the-art MOS sensor technology with intelligent detection algorithms to monitor tVOCs and CO2 equivalent variations in confined spaces, e.g. meeting rooms or vehicle cabins.

The dual signal output can be used to control ventilation on-demand, saving energy and reducing cost-of-ownership.
