WR295

 Digital Relative Humidity and Temperature Transmitter for Applications at Pressures up to 30 Bar (3MPa)
WR295 relative humidity transmitters include the interchangeable HYGROSMART module. The interchangeable module allows you to recalibrate the transmitter simply by replacing the sensor head. As a result, maintenance costs are greatly reduced and machine down time is minimized.
