Model PRO2 plus - Oxygen Indicator / Monitor
From Purge Monitors – Oxygen Indicators
The Pro2-plus is the latest addition to our line of oxygen indicators. Its updated design is extremely well suited to the welding industry and those types of corresponding applications. In the past, the very high quality welds that were required for the semi-conductor industry are now commonplace in aerospace, pharmaceutical, dairy, brewery and food industries, and with this unit these critical rest oxygen levels coan be accurately quantified. The Pro2-plus enables welders to precisely monitor when the rest oxygen levels have decreased to the point the precison welding can take place. As a result, this creates a welding environment that has the potential ability to reach a higher quality weld than was possible in the past.

Design Highlights
The Pro2-plus oxygen indicator contains a stabilized zirconium oxide cell with a regulated heater to maintain a cell temperature of 750°C which enables it to accurately measure levels from 206400 ppm down to levels as low as 1 ppm.
The zirconium oxide ceramic sensor utilized in the Pro2-plus provides very accurate readings, with a deviation of less than 5% in the 1 to 10 ppm range. This means that it’s resolution is ½ a part per million (ppm).
The Pro2-plus can be used in a portable configuration, unplugged from a wall power outlet for up to one hour of use before the internal battery must be recharged. This is a signifigant benfit for users welding in more remote inaccessable areas where normal 110v/220v power is not available.
