TAG Handy Purge 100 Plus Weld Purge Monitor

Portable, self-calibrating, self pumping digital oxygen monitor.
Measures oxygen levels down to 0.01% (100ppm)

High Purity Welding

Oxygen contamination is one of the most common reasons for substandard welds. Constant monitoring is necessary to ascertain oxygen has been evacuated to prevent oxidation, discolouration and coking. The enhanced 100 ppm resolution makes the Handy Purge 100 Plus perfectly suited for high purity welding.

Audiovisual Alarm

Oxygen contamination is one of the most common reasons for substandard welds.

The unit will produce an intermittent beep sound simultaneously as a green light flashes. The operator
is alerted and can continue evacuating oxygen, reset the alarm or commence welding.
