Oxy-Integral Portable Oxygen Analysers for TIG Welding

The new Oxy-Integral from Orbitec is accurate at titanium weld purging levels and, when integrated with the company's orbital welding controllers, can isolate the process and provide traceable documentation, enhancing safety and weld integrity. Oxy-Integral is a high accuracy oxygen meter (1-999ppm range) that uses a precision chemical cell (Zirconium Oxide) to determine low-volume oxygen levels compared with normal air. The unit can be calibrated in normal ambient conditions and will read down to one part per million.

With its integrated sampling pump, the latest models can be used independently, as an integrated unit with Orbitec's unique TIGTRONIC controller providing documented traceability or interfaced with any other orbital welding manufacturer's controllers.

The interlock function allows OxyINTEGRAL to be used as a condition isolator, preventing welding taking place where Oxygen levels are likely to cause oxidation or bad welds.

An optional analyser, the Oxy-2, provides calibrated measurement of pure or mixed inert gases and controls processes throughout the welding sequence.

A rechargeable battery pack and base station are standard features of OxyINTEGRAL and its light weight and ergonomic shape make it the ideal portable instrument for all orbital welding applications, whatever the equipment being used.

The Oxy-Integral is designed to process the output from an oxygen sensor made of stabilized zirconium oxide. This material is a ceramic, also known as a solid electrolyte and is ideally suited to high temperatures like those used as an oxygen ion conductor. Such ion conductors whose temperature range is dependent on the composition of the material, possess the capability to fill empty spaces in their crystal structure with oxygen ions. The oxygen ions attach themselves to conductive platinum surfaces. The degree of oxygen concentration in gas determines the degree of oxygen activity and thus, the quantity of oxygen ions.

The Oxy-Integral sensor consists of a solid electrolyte, which is exposed to gas on both sides. One side is in contact with a reference gas: air; the other with the gas to be measured. Using both heated and unheated sensors a computation is done to give an accurate reading. Maintenance and calibration-free make this the premium choice in oxygen analyzing.

The Oxy-Integral is a maintenance-free, non- depleting oxygen indicator with an operating range of 999 ppm to 1 ppm. This unit incorporates an internal pump and is designed for measuring rest oxygen in inert gases such as argon. Using the supplied battery charging station, this unit can be used up to 4 hours before recharging is necessary.
