For facility management and climate monitoring Hygro transducer, hygrothermal transducer, and CO2 measuring probe This measuring probe is mainly used in heating engineering, air-conditioning, and ventilation technology. It sets itself apart in particular through high measuring accuracy, long-term stability, and chemical resistance. LCD display Indoor, wall-mounted, duct, and rod versions Current, voltage, or Modbus output general technical dates Outputs - 4 to 20 mA, 0 to 1 V, 0 to 5 V, 0 to 10 V, and Pt100/Pt1000 (with T passive) Application - Building automation, storerooms, air conditioning and ventilation control systems Version - Indoor, duct, wall-mounted, and rod version CO2 sensing element - NDIR method (non-dispersive infrared technology) Protection type - IP20 indoor version; IP65 wall-mounted, duct, and rod version Humidity sensing element - Capacitive (resistant to condensation, fast response) Ambient temperature - -20 to +60 °C (indoor version, wall-mounted and duct version, CO2), -5 to +55 °C (indoor version with LCD display), -15 to +60 °C (wall-mounted and duct version, HVAC), -40 to +60 °C: rod version, wall-mounted and duct version (-20 to +50 °C with LCD display) Measuring range - CO2 = 0 to 2000/5000/10000 ppm, T = 0 to 50 °C (scaling active with analog output), RH = 0 to 100 % RH Accessories - Protective covers for outside and replaceable filters available as accessories Measurement medium - Air, pressureless sensor coating permits measurements in numerous aggressive media (exception: indoor version)
