RTX-CO2 Room CO2 Transmitter
Produal RTX-CO2
Multiparameter transmitter for CO₂ and temperature with Modbus or BACnet communication. It can be configured with the MyProdual app to create a P/PI control loop.
RTX-CO₂ room transmitters provide enhanced measurement of temperature, CO₂, humidity, and VOCs, as well as motion detection (PIR). With an unprecedented accuracy of ±0.3°C, RTX room transmitters set a new standard for accuracy in room temperature measurement. Note that with the -VOC and -R models, the temperature measurement accuracy is ±0.5°C.
Our patent-pending technology minimizes costs and environmental impact, maximizes comfort, and extends the building's lifespan. Thanks to the enhanced sensor properties, RTX room transmitters meet even the most stringent measurement requirements of sustainable building certification and rating systems (LEED (ANSI/ASHRAE Standard 62.1-2022), BREEAM, RESET Grade B, and WELL (WELL v2™)).
The multifunctional input allows you to connect external transmitters and sensors to the RTX to expand monitoring and control capabilities.
Standard features include temperature and CO₂ measurement, an integrated P/PI controller, seamless integration with existing devices and systems, and easy commissioning and configuration via the MyProdual mobile app. In addition to these standard features, you can choose from a wide range of options to create custom transmitters for your projects.
The integrated P/PI controller can control applications such as heating, cooling, ventilation, or VAV systems. The control output can be set to a single measurement value or the maximum value selected from all values.
With the MyProdual mobile app, you can quickly configure and commission the transmitters, as well as update their firmware. The MyProdual mobile app is free to download for Android from Google Play and for iOS from the App Store. In addition to the MyProdual app, you will also need an updated MyTool Connect Bluetooth dongle for the transmitters.
