Detailed Product Description

 Room IAQ Monitor / Controller

Real time monitor ambiance air quality with a mix gas sensor
Japanese semiconductor gas sensor with 5~7 years long life
Monitor temperature and optional relative humidity
LCD can display IAQ level and temperature, humidity(option), fan status etc. Makes reading and operating easy and accurate.
All models feature user-friendly setting buttons
Locale adjustable ranges are : IAQ 0~30ppm, temperature 5~45, humidity 595%RH
RS-485 communication interface optional, 15KV antistatic protection, independent base address setting
Up to 1x0~10V analog output and 2xrelay dry-contact outputs
Two alternatives for the analog output : linearized over full range output or PID control output.
The relays can be selected to control IAQ , temperature or humidity (programmable setting)
Timer of turning-off function for the ventilator device from 0.5 to 12 hours.
