This compact dew point sensor is suitable for refrigerant, desiccant, drum and membrane dryers. Its proven polymer film technology provides strong contamination resistance. The precision sensor design compensates for drift caused by temperature, contamination and aging, providing long-term, reliable, high-accuracy measurements.
Best Suited to:
- Compressed air and gas systems to 4 MPa (600psi)
- Refrigerant, Drum and Membrane dryers operating above -40°C (-40°F)
- Dew point range of -60°C to +60°C (-76°F to +140°F)
- Cost sensitive applications
- Small spaces
- Flow rates greater than 1 L/min
- Permanent or temporary installation
