Oxygen analysis down to ppm Gas technology manufacturer Witt has unveiled a new development that can measure trace oxygen levels. The gas analyser PA 7.0 enables reliable analysis in the ppm (parts per million) range. major problems, such as undesired oxidation. A highly sensitive zirconium cell, available as an option, allows the PA gas analyser to detect trace quantities of oxygen in gaseous media. This extends the PA product series into a new area of gas analysis. While In many industrial processes, even the smallest amounts of oxygen can cause

the classic PA with chemical sensor measures in increments of 0.1 per cent, the new zirconium version detects in the ppm range. The accuracy of the measurements is ±5 per cent relative to the measured value. All measured values are stored, and can be downloaded via a standard interface for further processing. Weighing just under 6kg, the PA is only 186 x 285 x 270mm in size, and is protected by a stainless steel housing. The new PA version is part of an exten- sive product portfolio comprising mobile and stationary systems for gas applications, especially in food packaging, medical applications, metalworking and glass production, as well as in industrial processes requiring a high degree of precision.
