PurgeNet™ Dew Point Purging Gas Moisture Sensor™

Eliminate porosity. Monitor moisture. Protect critical welds.
The PurgeNet™ Dew Point Purging Gas Moisture Sensor™ is designed to work directly with PurgEye® Weld Purge Monitors® to measure moisture content and dew point conditions during welding. By monitoring both oxygen and moisture levels in real time, this system helps prevent porosity, cracking, and contamination in critical weld joints.

Unlike traditional standalone dew point meters, this sensor integrates directly into your existing PurgEye® system—saving cost, simplifying setup, and improving weld quality.

Why Welders Use the Dew Point Purging Gas Moisture Sensor™

• Prevent Porosity & Cracking: Monitor moisture before contamination affects the weld
• Improve Weld Quality: Maintain proper purge conditions for critical joints
• Real-Time Monitoring: Instantly detect changing purge gas conditions
• Cost-Effective: Eliminates the need for a separate dew point meter

Why Dew Point Matters in Welding

What is Dew?
Dew is liquid water that condenses from the atmosphere onto surfaces such as metal.

What is Dew Point?
The dew point is the temperature at which air becomes saturated with water vapor and condensation forms.

Why is moisture a problem?
Under welding arc conditions, water breaks down into hydrogen and oxygen. These gases can cause porosity, cracking, and contamination in the weld joint.

Why monitor moisture during purging?
Monitoring moisture is critical during long or high-purity welds where purge conditions can change during the welding process.

Benefits of Moisture Monitoring

• Reduce weld defects caused by moisture contamination
• Improve weld consistency and reliability
• Protect high-purity and critical weld joints
• Ensure proper purge gas quality throughout the welding process

Ideal For

• High-purity TIG welding
• Aerospace and semiconductor fabrication
• Pharmaceutical and food-grade welding
• Titanium and Inconel® applications
• Critical pipe and vessel welding

Frequently Asked Questions

What does this sensor measure?
It measures moisture content and dew point conditions during welding purging operations.

Why is moisture monitoring important?
Moisture can introduce hydrogen and oxygen into the weld, causing porosity and cracking.

Does this replace a dew point meter?
Yes. It integrates with your PurgEye® system, eliminating the need for a separate dew point meter.

What PurgEye® monitors is it compatible with?
It works with PurgEye® 200, 500 Desk, 600, 1000 Remote, and 1500 Site models.

Does it require separate power?
No. It is powered directly through the PurgeNet™ lead.
