Indoor air quality transmitter is equipped with precise CO₂ measurement based on the industry-standard NDIR principle, featuring an automatic calibration function that ensures long-term accuracy and reliability. In addition to CO₂, the device can also measure temperature and humidity, making it suitable for a wide range of indoor air monitoring applications.

Air quality transmitter offers flexible installation and adjustment options. Models with a built-in user interface include a display and buttons, allowing for easy on-site configuration. For models without a user interface, the Siro-CT configuration tool is available to simplify setup. 

Air quality transmitter provides configurable output signals, and each measured parameter can be adjusted independently to suit different system requirements.

The transmitter supports analog output with a 0–10 VDC signal range. MOD models are also available and can be connected to systems supporting Modbus RTU via RS-485, enabling seamless integration into building management and HVAC systems.

Particulate Matter Transmitter- It allows monitoring the concentration of PM1, PM2. 5 and PM10 particulate matter with high accuracy and reliability thanks to its laser light technology and the digital filtering and averaging of the measurements.

Equipped with industrial standard RS485 Modbus RTU signal output, the Indoor Air Quality Transmitter is widely used in HVAC systems and BMS systems for acquiring reliable indoor air quality measurements. The compact and minimal design makes the sensor configuration more flexible and easy for the system integrator. The recommended installation height is 1 to 2 meters above the floor level.

To put it simply, an IAQ monitor is a device or system that checks the levels of different air contaminants and helps assess how safe the air is to breathe. It can alert people when some of those levels become unsafe.

Sensors Vietnam offers air quality transmitter - an ideal solution for ventilation control, air quality monitoring, and smart building applications where accurate and efficient CO2 sensing is required.
