The all-new Mark V Weld Purge Monitor from HFT (Huntingdon Fusion Techniques) has been designed from scratch for additional reliability and accuracy (Plate 5). With back- sealed oxygen sensor and screw-thread sensor housing, the instrument is ruggedised for field use and designed specifically for use at weld purge levels.

Mark V Welding Purge Monitor
Although one of a number of instruments being sold for weld purging, the HFT Mark V is built and calibrated at weld purging concentrations of oxygen, ensuring accuracy for welding of stainless steel and exotic metals. Most competitive monitors are made for safety monitoring and calibrated to atmospheric oxygen levels and can be slow to react in low-oxygen environments, leading to unreliable weld conditions.
Completely redesigned to ensure that all HFT's market criteria were met, the Mark V Weld Purge Monitor has a new, back-sealed oxygen sensor ensuring that only gas from the purge volume is contacting the chemical cell, a new, more rugged enclosure that affords better protection and a reinforced, easy-read LCD display. The purpose- designed integrated PCB and display is lighter and free from loose, soldered wires that can lead to electronic failure. A highly-sensitive potentiometer allows precise calibration to 0.01 per cent of reading.
With an easily replaceable sensor, the new instrument features a screw-thread sensor housing for added stability and with less chance of gas leakage which can cause erroneous readings. The sensor unit is interchangeable with all previous HFT models, ensuring compatibility throughout the range.
