Air Quality (VOC)

Intelligent combined sensor for
Air Quality (VOC), Humidity (rH) and Temperature (T)
with analogue outputs, Modbus and LCD Display,
type QHT 24R

The intelligent sensor QHT 24R offers long term high stability and accuracy for all measured parameters Air Quality (VOC), Humidity (rH) and Temperature (T).

QHT 24R have three selectable outputs 0-10 Vdc, 4-20 mA or 0-5 Vdc for each parameter of Air Quality (VOC), Humidity (rH) and Temperature (T), the outputs are corresponding to 0 to 1000 ppm, 0 to 100% RH and 0 to 100 degrees Celcius.
