Features

1. Real time monitor ambiance air quality with a mix gas sensor

2. Japanese semiconductor gas sensor with 5~7 years long life

3. Monitor temperature and relative humidity

4. LCD display air quality as well as temperature and humidity, fan status etc. Makes reading and operating easy and accurate.

5. user-friendly setting buttons

6. Temperature and humidity compensation makes the IAQ measurement more consistent in different environments

7. Modbus RS-485 communication interface optional, 15KV antistatic protection, independent base address setting

8. Up to 1x0~10V analog output and 2xrelay dry-contact outputs

9. Two alternatives for the analog output : linearized over full range output or PID control output.

10. The relays can be selected to control IAQ , temperature or humidity (programmable setting)

11. Timer of turning-off function for the ventilator device from 0.5 to 12 hours.

12. Low power consumption

13. Buttons make operation easier.

Application

F2000IAQ-VOC is specially designed to detect indoor air quality in offices and home environments. Its internal gas sensor has high sensitivity not only to VOC's such as toluene emitted from wood finishing and construction products but also to other air contaminants which are emitted by cigarette smoke, ammonia and H2S. It’s also sensitive to carbon monoxide, alcohol, natural gas and smell from people’s body. So it is more suitable for monitoring IAQ than other sensors which one is only for one kind of gas.

1. Ambiance air quality detection and alert

2. Ventilation control

3. Air quality monitors

4. Odor monitors.
