QUICK SUMMARY TO HELP YOU CHOOSE THE BEST MODEL:

  • PurgEye® 100 IP65, low cost, dustproof and waterproof hand held unit for reading down to 100 ppm. With innovative push button auto calibration, enlarged screen, low sensor indicator, tripod mount, sleep mode, vacuum sealed leak-tight probe assembly, wrist or neck strap, rubber housing protector and so much more.
  • PurgEye® 200 with PurgeNet™ is our hand held, rechargeable battery driven Weld Purge Monitor® for reading very accurately down to 10 ppm complete with electromechanical pump. The PurgEye® 200 also has an IP65 rating for its housing that is sealed against the ingress of dust and water.
  • PurgEye® 300 Nano, the worlds first and only super low cost, entry level, mains power driven Weld Purge Monitor® measuring accurately down to 10 ppm.
  • PurgEye® 500 Desk with PurgeNet™ uses an internal electro-mechanical pump to draw the gas across the sensor. It also has the switching capabilities and the PurgeLog™ Software.. This equally attractively priced instrument includes a unique, fast response, lifespan sensor with virtually no maintenance required. Reads accurately down to 10 ppm
  • PurgEye® 600 a computerised, touch screen model measuring very accurately from atmospheric level of oxygen, down to 10 ppm, with high and low oxygen level switching capabilities, data capture via USB using PurgeLog™ software for recording purging results for evaluation and provision of a quality control document. Readings are indicated either as parts per million or in percentage.
  • PurgEye® 1000 monitor with PurgeNet™ has been developed for those instances where the measuring point is more than 20 metres away from the monitor. The slow time for the gas to travel and reach the sensor and the contamination of actual reading that can take place inside the gas tube, leads to serious delays and erratic readings. To improve this, the sensor is placed in a small module attached to a weld purge system and the reading transmitted instantaneously to a hand held display via a data cable. Reads accurately down to 10 ppm.
  • PurgEye® 1500 Site with PurgeNet™, designed and manufactured in a robust, virtually non-destructible case, perfect for dusty, hazardous, on-site conditions, measuring oxygen levels from 1,000 ppm down to 10 ppm. IP68 rated with the lid closed.

What is PurgeNet™? 

PurgeNet™ controls the welding power sources such as orbital welders and any other automatic welding systems to switch on and off according to oxygen levels. PurgeNet™ can be used with PurgeLog™ software to transfer weld purge data for quality control of welds. PurgeNet™ connects to other smart accessories for weld purging, including the Traffic Light System, which gives a visual warning during welding in case of rising of falling oxygen levels. PurgeNet™ is in fact a network that allows connection with a range of other accessories to be announced in the future.

Weld Purge Monitor® was invented by HFT® in the 1970’s. Registered Trademarks in USA and Europe. Note that the Argweld® Mark V (MKV) does not feature as this meter is now very much out of date and this old technology has been replaced by the latest 'most popular' state of the art instrument, the PurgEye® 100 IP65 Weld Purge Monitor®.
