The PRODUAL Siro-CO2-T-D 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.

The PRODUAL 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. 

The PRODUAL 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.

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