HUNTINGDON Fusion Techniques’ (HFT) Weld Purge Monitor can detect atmospheric levels of oxygen down to one part per million (ppm), which the company says breaks all technological boundaries in one instrument.

The PurgEye 600 incorporates the features and benefits of all the other Weld Purge Monitor designs in the HFT family range, but includes a full range of measurement reading from atmospheric concentration (20.94%), down to 1 ppm, accurate to 10 ppm.

Readings are indicated either as parts per million or in percentage.

The PurgEye 600 has a life time sensor that won’t need replacing or recalibrating, HFT said.

The instrument has been designed with a large, full colour touch screen and on-screen graph of the oxygen levels during the welding process.

USB data logging capability allows the operator the ease of data transfer without the need for a computer connection.

The results can be downloaded for each weld, which is read using the PurgeLog data logging software.

In addition, the instrument includes an internal sampling pump with gas filtration, which means there is no requirement for an external hand pump.

The PurgEye 600 Weld Purge Monitor gas detection and analysing instrument is ideal for industries such as aerospace, pharmaceutical and food and drink, as well as many others where oxide free, zero colour welds have to be achieved and where traceability is a major advantage for the requirements of high-end quality control systems.
