- WR293温湿度变送器
WR293 relative humidity sensors use the HYGROSMART module, integrated in the interchangeable probe and cable. The device can be used in high-temperature applications thanks to the remote measurement element and small overall size. The interchangeable probe allows simple recalibration and lower maintenance costs.
