IAQ Transmitter/Controller Indoor Air Quality (VOC) / IAQF Formaldehyde (CH2O)

IAQFW/xxxxx

IAQW/IAQD are specially designed to detect various air pollutants (VOCs) in the air content including wood, paint and others produced by toluene, cigarette, ammonia odor, CO, alcohol, natural gas and even body odor. While IAQFW/IAQFD are specific only for CH2O in air
IAQW/IAQFW are for the room and IAQD/IAQFD are for duct mounting
IAQW/IAQD uses a highly sensitive metal oxide semiconductor gas sensor with a sensor life of up to 5~7 years.
IAQFW/IAQFD uses a high performance electrochemical gas sensor with a service life of more than 3 years.
All sensors are low power consumption with good temperature and humidity compensation.
