HVAC - sensors

Every year, Tasseron builds millions of sensors for various applications in the field of heating, ventilation and air conditioning (HVAC). Our unique ‘off the shelf’ solutions are convenient to install. They utilize the patent-pending Quick Connect system, which can reduce installation time for large jobs by hours. Everyone who uses our HVAC sensors loves them. Get these sensors in your hands and see the difference in quality and design for yourself.

Besides temperature sensors, we also develop and produce high-quality sensors for measuring CO2, RH, VOC and air velocity. Whether it’s about measuring in a room, a duct or outdoors, we have a suitable solution for every application.

CO2-VOC-RH-T combination

Sensors

A good environment is of paramount importance. With our sensors you can monitor and control the key factors that attribute to this. You can combine CO2, VOC, RH and T in just one enclosure. Available as duct or room version.
