The E Series Dew Point Sensor is rated IP67, making ideal for outdoor use. It measures dew point, temperature and relative humidity of compressed air and inert gases (argon, carbon dioxide, carbon monoxide, helium, hydrogen, nitrogen and oxygen). The sensor comes with a touch screen display, alarm relay and two output options – 4-20mA and Modbus.
Best suited to
- Indoor or outdoor use
- Compressed air and gas systems to 4 Mpa (600psi)
- Membrane, drum, hybrid, refrigerant or desiccant dryers
- Temporary or permanent measurement
