RHT-Air is a fully wireless solution for measuring temperature and humidity over long distances, allowing the configuration and reading of the parameters through the wireless network up to 500 m, bringing practicality and efficiency to the application.


It has long battery life - which can operate as a no break - combined with the convenience of a wireless sensor that avoids the absorption of electrical noise, ensuring a robust and safe solution.


Operation without cables and wires simplifies the installation. In addition to the ease of reallocation of the devices, it is possible to extend the telemetry network extremely easily: simply attach the new sensor where necessary and configure it from a distance!


Moreover, RHT-Air operates on its own wireless network, without the need to use the company's IT infrastructure, allowing its stand-alone operation.
