HVAC - Humidity
Aside from temperature sensors, we also build high quality sensors specifically for the purpose of measuring humidity. Whether it’s room humidity, duct humidity or outdoor humidity, we have a fitting solution for every application.
Duct humidity
sensors
For reliable and accurate duct humidity measurements, we have developed moisture resistant sensors with coated circuit boards and polycarbonate covers. To prevent contamination, they are also equipped with dual filters. All of our duct humidity sensors ensure an easy installation. Also available with accurate thermistors and RTDs.
