RTX-CO2 room transmitters provide improved temperature, CO 2 , humidity and VOC measurement as well as motion detection (PIR). With their unprecedented ±0.3 °C accuracy, RTX room transmitters set a new degree of accuracy for room temperature measurement. Note that for -VOC and -R models, temperature measurement accuracy is ±0.5 °C.
Our patented technological solution minimises costs and environmental impact, maximises comfort, and extends the building's life cycle. With improved sensor properties, RTX room transmitters comply with even the strictest measurement requirements of certification and rating systems for sustainable buildings (LEED (ANSI/ ASHRAE Standard 62.1-2022) - BREEAM - RESET grade B - WELL (WELL v2™)).
Multifunctional input enables you to connect external transmitters and sensors to RTX to broaden monitoring and control capabilities.
Standard features include temperature and CO 2 measurement, built-in P/PI controller, seamless integration with existing devices and systems, and easy commissioning and configuration with MyProdual mobile application. In addition to these standard features, you can pick and choose other features from a wide range of options to build transmitters that best suit your projects.
The built-in P/PI controller can control, for example, heating, cooling, ventilation or VAV applications. The control output can be controlled according to one measurement value or according to the maximum selection of all values.
With the MyProdual mobile application, you can configure and commission transmitters quickly, as well as update the transmitter firmware. You can download MyProdual mobile application for Android from Google Play and for iOS from App Store free of charge. In addition to MyProdual application, you will also need an upgraded MyTool Connect Bluetooth dongle for the transmitters.
