Room Air Quality (VOC) Transmitters
The self-calibrating microprocessor-controlled room air quality transmitter QRT 24-series is used to determine the room air quality on basis of a mixed gas sensor / VOC sensor (VOC = Volatile Organic Compounds).
Duct Air Quality (VOC) Transmitter,
The self-calibrating microprocessor-controlled duct air quality transmitter QDT 24 used to determine the room air quality on basis of a mixed gas sensor / VOC sensor
(VOC = Volatile Organic Compounds).
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.
Duct Air Quality VOC/CO2 sensor, BIO 2000 DUCT
The duct air quality VOC/CO2 sensor BIO 2000 DUCT have VOC/CO2 measuring range 0-2000 ppm with output sinal (0)2-10 Vdc or (0)4-20 mA, the BIO 2000 DUCT is equipped with Modbus RS-485 as standard
Room Air Quality VOC/CO2+T sensor, BIO 2000 ROOM
The room air quality VOC/CO2+T sensor BIO 2000 ROOM have VOC/CO2 measuring range 0-2000 ppm with output 0-10 Vdc and the Temperature measuring range is 0 to 30 degrees Celcius with output 0-10 Vdc, the BIO 2000 ROOM is equipped with Modbus RS-485 as standard
