PurgEye 200 IP65 Hand Held Purge Monitor

Argweld PurgEye 200

Rechargeable Weld Purge Monitor is a high accuracy hand held unit that reads oxygen content down to 0 to 10 ppm.  


Argweld PurgEye 200 Hand Held Purge Monitor, comes with an integral electro-mechanical vacuum pump and a rechargeable battery.

This Hand Held Purge Monitor can be used as a continuously reading instrument with free flow of the purge exhaust gas across the sensor, or as a sampling instrument with the integral electro-mechanical vacuum pump. The unit is a residual oxygen monitor used to measure the quality of purge in the weld area.

The Argweld® PurgEye® 200 Rechargeable Weld Purge Monitor®  contains 4 standard rechargeable AA batteries and is supplied with a rechargeable battery unit and charger.

The large alpha-numeric display is easy to read and can be easily switched to display readings in ppm or percentage.

The Argweld® PurgEye® 200 Rechargeable Weld Purge Monitor® has a working temperature between 0 and 70°C (32 and 158°F) and a two minute warm up time.

Note: Use only 6mm OD polyurethane weld purge tubing. The leak tight quick fit couplings are specifically integrated so that the user will not have leaks of air into the critical purge zone. Do not use other tubing because it will not fit properly and it will cause leaks.

Hand Held Purge Monitor

Compact form factor, easily transportable and can be used in small areas

Warning Alarm

The warning alarm can be set to any level between 1 and 999 ppm and has both audible and visual indication when the alarm threshold is exceeded.

Flow Detection

The flow warning exclamation icon will be displayed whenever the flow of sample gas drops below the minimum flow rate required for an accurate reading. Please note, this could be due to a blocked filter in need of replacement.
