IAQ indoor air quality transmitter controller VOC monitor

 IAQ Indoor Air Quality Transmitter/Controller (VOC)

Applications & Features

• Detect varies air contaminants that influence air quality
• IAQW for wall mount, IAQD for duct mount, light and state of art housing, easy installation
• Especially high sensitive for VOC in air content such as wood, paint and other building products produced by toluene, and other air pollutants such as cigarette smoke and ammonia odor
• Meanwhile high sensitive to CO, alcohol, natural gas and body smell
• High performance metal oxide semiconductor gas sensor,up to 5~7 years service life, low power consumption, with good temperature and humidity compensation
• Power and outputs over voltage and reverse polarity protection, high reliability and anti-interference capability
• All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring(IAQW)
• Bright multi-color light bar, indicating air quality status(IAQW)

Note:
1. VOC is a general term for all kinds of Volatile Organic Compounds,
which may include over a thousand kinds of component. The most
common are benzene, toluene and xylene, ethyl benzene, styrene,
formaldehyde, TVOC (6-16 carbon alkanes, ketones). These compounds
are widely used in footwear, toys, paints and inks, adhesives, cosmetics,
indoor and automotive decorative materials and other industrial fields.
VOC has a great impact on human health, may affect the human liver,
kidney, brain and nervous system, resulting in memory loss and other
serious consequences, and even cause cancer.
Outdoor VOC comes mainly from the combustion of fuel and transport.
Indoor VOC comes mainly from coal and natural gas combustion products,
smoking, heating and cooking, building and decoration materials, furniture,
household appliances, cleaning agents and human body discharge.
2. The sensor could detect the air quality of varies VOC concentration. Its
0~10VDC/4~20mA output is equivalent to CO2 concentration of range
0~2000ppm.
3. Sensor has good long-term stability, consistency and repeatability <10%
4. Relevant researches show that exposed to 0.5~1.0 ppm or below VOC
concentration environment have generally little impact on most people
health; exposed to 1.0~10 ppm VOC concentration environment have
obvious eyes, skin, nose, mouth and throat irritation symptoms on human
and cancer rates rise 50% to 90%; exposed to the VOC concentration
above 10 PPM may have serious impact on human health or life
threatening.
5. Relevant GB/T18883 and GB50325 IAQ regulations specified the
average 8 hours TVOC limit 0.50~0.60 mg/m3 (equivalent to about 500
ppb)
6. VOC concentration guidelines and recommendations, formaldehyde for
reference mainly, as shown in right chart.
