DT284

 Digital Relative Humidity and Temperature Transmitter Remote Version
DT284 relative humidity sensors use the HYGROSMART module, integrated in the interchangeable probe. The device can be used in high-temperature applications thanks to remote placing of the measurement element and small overall size.
