The HHAQ-104 is designed to measure O2 concentration, pressure, air temperature and relative humidity with visible and audible alarms. This O2 monitor is an ideal instrument for indoor air quality (IAQ) diagnosis and HVAC system performance verification. The HHAQ-104 features a remote probe and detachable soft in/out tube to reach air-ducts or where access with the probe is not possible.
