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.
