SIRO is an indoor air quality transmitter with a modern design. The transmitter is available with several optional air quality sensors. The modular device can be equipped with CO2 concentration and VOC (Volatile Organic Compounds) measurements or alternatively PM (Particulate Matter) measurement, and in addition, temperature and humidity measurements. SIRO-MOD series models use Modbus serial communication protocol.
Measuring elements:CO2: Non-dispersive infrared (NDIR); 0...2000 ppm VOC: Complementary Metal Oxide Semiconductor (CMOS); range: * - see datasheet PM: Laser-based light scattering particle sensing Temperature: Integrated to CMOS Relative humidity: Thermoset polymer capacitive sensing element Field configurable outputs for selected measurements; Configuration possible through MODBUS Proportional output options including voltage (0–10 V, 0–5 V, 2–10 V) and optional current (4–20 mA); MODBUS Offset feature enabling field calibration for each measurement parameter (CO2, VOC, PM, RH, T) Optional LCD-display and buttons Operating temperature: 0…50 °C Protection standard: IP20
