4-in-1 Air Quality Display


AQD series displays four most crucial parameters of IAQ; CO2 level, PM2.5 concentration, humidity and temperature. It also provides date, day and time. It uses good quality sensors; such as the NDIR CO2 sensor, laser scattering principle sensor for PM2.5, temperature and humidity sensors which are usually available only in laboratory air quality diagnostic equipment. AQD-101 series measures CO2 and PM2.5 concentration which may not be noticeable by us and used the reading to control ventilation so that the indoor CO2 level can be kept below the recommended ASHRAE limit of 1000ppm and it can ensure better indoor air quality. Monitoring humidity is very important as extended period in an area with humidity over 60% or below 40% can create conditions for mold and mildew growth that may cause allergies and affect general health.


  • Smart Air Quality Monitor
  • It can be connected to ventilation system. Wind volume from ventillation can be adjusted according the measurement value to reduce indoor CO2 and PM2.5 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/PM2.5, 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.
