VOC Detector

The Ace Instruments VOC (Volatile Organic Compounds) detector Model AI-VOC-D is a state of the art instrument to measure the VOC in air quality measurements in HVAC & air quality monitoring applications. The VOC detector transmits the VOC signal as an analog 4-20mA output. The VOC detector’s sensor used is a MOX (metal oxide) based gas sensor. The VOC detector helps in analyzing the indoor air quality in demand control ventilation systems, offices, meeting rooms, hotels, convention centres, stores, restaurants, manufacturing facilities, pharmaceutical industry & apartments. The VOC detector accurately transmits the VOC concentration levels over analog signal or RS 485 modbus communication. For the specifications given below, ethanol in clean air has been used as proxy gas for typical indoor air events.

The VOC detector gives 2 individual analog 4-20mA outputs, 1 each for the duct VOC concentration & temperature in Deg. C. The VOC measurement range is from 0 to 500 PPM (Ethanol in clean air is used as proxy gas) & the robust algorithm makes the instrument sensitive to most VOC gases typically present in indoor environments emanating from cigarette smoke, human breath, body perfumes & deodorants, solvent vapours , paints & facility cleaning materials.

An optional RS 485 modbus communication is available for connecting to BMS/EMS in multi-drop topology
