Key Features
It can be connected to ventilation system. Wind volume from ventillation can be adjusted according the measurement value to reduce indoor CO2 density. Additonally, it provides the value of indoor temperature and humidity as a reference of comfort and air quality.
Features:
- Continuous monitoring: non-stop detecting and monitoring, complete record, real time update, meet the criteria of " Taiwan indoor air quality act".
- Alarm function: 3 relay output, respectively corresponding to CO2, temperature and humidity. They can activate the HVAC equipment to maintain indoor air quality and save energy.
- Built-in memory: configurations can be stored after power off.
- Meet the criteria of " Taiwan indoor air quality act": record of hourly average value and 8-hour average value
- Data access: with AUS-001 RS485 to USB converter, user can read measurement data from computer
- A calender with year, month, date, day and time.
