Overview
The BV27 air quality module uses an advanced chip thick film semiconductor gas sensitive element. The module has good sensitivity to volatile organic gases such as formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol and smoke of cigarette, essence & etc. The module has been aging, debugged, adjusted and calibrated. So it has good consistency and high sensitivity.
Key Features
- High sensitivity
- Excellent long-term stability
- Low power consumption, long life
- Calibrated before shipment
- High cost-effective
Applications
Air cleaner, fresh-air system, intelligent integrated ceiling, air quality detector, ventilator, air-condition.
