Dew Point SensorDew Point Sensor for accurately measuring the dew point.

During purging welders need to measure the oxygen content but also need to measure the ‘dew point’.

The dewpoint is the temperature where condensation begins and water will condense on the material being welded. This can affect the weld properties significantly.

We have recently added a Dew Point Sensor to our range that can be used in conjunction with our range of 10 ppm Weld Purge Monitors®, so rather than purchasing a separate, expensive Dew Point Meter, HFT®’s Dew Point Sensor that can be connected to the Weld Purge Monitor® via the PurgeNet™ lead.

The dew point sensor is designed to fit any of our Weld Purge Monitors® that read down to 1ppm:

- PurgEye® 200

- PurgEye® Desk

- PurgEye® 600

- PurgEye® 1000

- PurgEye® Site
