Titanium Purge Monitor




The Argweld ® Titanium Purge Monitor has been specifically designed for indicating oxygen levels in Argon gas for weld purging.

It measures and clearly indicates actual oxygen levels in parts per million down to 10 parts per million on an alpha-numeric display.

The unit is menu driven by four buttons on the front panel and has an internal alarm with high and low oxygen levels which can be set on the front panel.

A unique new sensor is used which has very little maintenance requirement and tests have shown that it should last up to five years.

An optional software package is available to allow a computer to be used to store and print results and graphs etc for quality control purposes.
