1.Real time monitor ambiance air quality with a semiconductor mix gas sensor with 5~7 years long life
2.Special design to detect indoor air quality in offices and home environments.
3.Its internal mix gas sensor has high sensitivity not only to TVOC'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. Its also sensitive to carbon monoxide, alcohol, natural gas and smell from peoples body.
4.LCD displays IAQ level and temperature, humidity(option), fan status etc. Makes reading and operating easy and accurate.
5.All models feature user-friendly setting buttons
6.RS-485 communication interface optional with 15KV antistatic protection,
7.Up to 1x0~10V analog output and 2xrelay dry-contact outputs
8.Two alternatives for the analog output : PID control output or linearized over full range output
9.The relays can be selected to control IAQ , temperature or humidity (programmable setting)
10.Timer of turning-off function for the ventilator device from 0.5 to 12 hours.
11.Low power consumption
