WR295

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