Dew Star R-1
Chilled Mirror Dew Point Hygrometers with separate probe

With its feature as standard of humidity measurement and humidity management of industrial applications, Dew Star series has been adopted in worldwide for wide range of applications over the decade since its release. Our new Dew Star R-1 series, probe separate type has achieved wider applications of dew point measurement with its original accuracy and reliability. Dew Star R-1 series enables dew point measurement in smaller space, various testing chambers and more applications.

Sensor Probe

Sensor probe integrated in the test chamber –offers monitoring the lab from outside

Sensor probe of Dew Star R-1 Chilled Mirror System enables users to monitor the inside atmosphere with the monitor settled at the monitor room. The monitor of the system can be chosen from desktop type or rack-mounted type.

Monitoring dew point of torque meter in automobile applications

Dew Star R-1 sensor probe can be installed directly inside the chamber in measuring the dew point.

Best solution for the calibration standard of humidity in chamber with its long-term stability

Dew Star R-1 series can work as the calibration standard with its long-term reliability and repeatability which is traceable to national standards.
