Overview
BV12-NV614 air-quality module adopts flat surface semiconductor gas sensor. The module has very high 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 and good long-term stability
- Calibrated before shipment
- 10 seconds to 3 minutes with auto-preheating function
- Faulty auto-check, low power consumption
- Long lifespan, high cost-effective
Applications
Air cleaner, fresh-air system, intelligent integrated ceiling, air quality monitor, ventilator, air-condition.
