Keep a distant 'Eye' on your Weld Purge... up to 1 km away!
The World's 'first and only' remote (long Distance) Weld Purge Monitor®, measuring accurately down to 10 ppm. With an internal electro-mechanical pump, battery or mains power driven and now with PurgeNet™.
PurgEye® 1000 Remote Sensing Head can be fitted onto a mechanical or inflatable purging system, directly at the weld location and will measure oxygen level in the purge gas and transmit the information electronically to the monitor up to 1 km away. With this capability, operators can obtain an instantaneous and correct weld purge reading no matter how far they are from the weld and be certain that the joint will not be adversely affected by oxidation.
Our Weld Purge Monitors® have been specifically designed for excellent weld purging conditions creating the best oxide-free zero color welds. Oxygen monitors for welding purposes, including gas analysers (gas analyzers), oxygen instruments or oxygen indicators are not sufficient to provide good clean welds.
PurgEye® a 'Family' Series of Weld Purge Monitors® invented by HFT® in the 1970’s. Registered Trademarks in USA and Europe.

Measuring down to 10 ppm as far as 1 km away
When welding joints in long tube line or pipeline sections, it may not be practical to measure the purge gas exhaust close to the weld.
Measuring purge gas exiting in the joint gap is also unsatisfactory because of the the oxygen being drawn in from outside and other variable factors.
HFT® has developed an answer to this difficulty, namely a sensing head that can be fitted onto the purging system, directly at the weld location and will measure oxygen level in the purge gas and transmit the information electronically to the remote monitor and operator that may be up to 1 km away.
In this way, the operator can be certain that the weld purge reading is correct and that the joint will not be adversely affected by oxidation.
Portable ‘handy’ Purge Monitor, reading from 1000 ppm down to 1 ppm (accurate to 10 ppm).
The PurgEye® 1000 Remote, now with PurgeNet™ is equipped with a stainless steel sensing head, which connects onto any Inflatable or mechanical Tube, Pipe and Pipeline Weld Purging System, producing accurate readings up to 1 km away from the weld.
The sensing head and the integral electro-mechanical pump are powered by the data cable, so only one cable is required. The sensor head is small enough to fit inside pipes from 1” (25 mm) diameter, upwards and is easily manoeuvred through pipes.

Weld Purge Monitoring Now with PurgeNet™
The PurgEye® 1000 has been developed with a sensing head that can be fitted onto the Tube, Pipe and Pipeline Weld Purging System, directly at the weld location and moved from joint to joint. The new, fast response, zirconia oxygen sensor will measure oxygen level in the purge gas and transmit the information electronically to the monitor, up to 1 km away.
The PurgEye ® 1000 now comes complete with PurgeNet™, which can control Automatic Welding Systems as well as Orbital Welders, causing them to switch on and off for example when oxygen level rises too high or falls too low.
The IP66 Rated (Environmental Protected) PurgeAlarm™ displays a red indicator, if the monitor reading has a greater value than the alarm threshold set by the user.
An optional green indicator can be fitted above the standard red indicator and will illuminate if the reading has a value lower than the alarm threshold set but the user. A sounder is available as an option to provide an audible alarm instead of the red light.
PurgeNet™ also works with PurgeLog™ to easily transfer weld purge data for Quality Control purposes.
The Argweld® PurgEye® 1000 Remote Weld Purge Monitor® comes with a hand held display, a sensor head hermetically sealed inside a small round stainless steel tube and a 10 m lead as standard.
Optional Docking Station for charging the battery if required. The unit will run from 100 – 250 volts, 50 hz supply.
Other features of the PurgEye® 1000:
- Optional 100 m reel of outdoor cable with locking connectors.
- Reels of extension cable can be connected together to make longer leads up to 1 km.
- Shorter or longer lengths can be supplied to order to suit application.
- PurgEye® 1000 display, battery or mains powered.
Suitable for fitting to mechanical or inflatable purging systems for 1” diameter pipe and larger.
- The head will be powered from the data cable, so only one cable is required.
- Because the unit is small and round, it is easy to pull through pipes.
Huntingdon Fusion Techniques HFT® are bringing yet another innovation to the market place with this new PurgEye® 1000 Remote Weld Purge Monitor®. Weld Purge Monitors® have been developed and manufactured by HFT® specifically for welding of high quality materials as ordinary oxygen monitors cannot achieve the accuracy required for welding purposes.
HFT® use real science and technology to create proven and original products.

Use only weld purge hose leak tight quick disconnect fittings suitable for connecting 6 mm OD polyurethane tubing. Do not try to use other diameter tubing because it will not seal properly and will end up causing leaks.
The PurgEye® 1000 Remote Weld Purge Monitor® is simple to use, real plug and play.
The sensor A is connected to the exhaust of the purging device, which is located directly at the weld site.
The exhaust purge gas flows through tube A and is measured by the remote sensing unit B, which sends the results electronically back to the display unit C.
The sensing head B can be supplied with fixing brackets so that it can be fitted to an internal pipe clamp with purging seals or stand alone pipe weld purging system.
Dew Point Sensor
During purging welders need to measure the oxygen content but also need to measure the ‘dew point’.
The dewpoint is the temperature where condensation begins and water will condense on the material being welded. This can affect the weld properties significantly.
We have recently added a Dew Point Sensor to our range that can be used in conjunction with our range of 10 ppm Weld Purge Monitors®, so rather than purchasing a separate, expensive Dew Point Meter, HFT®’s Dew Point Sensor that can be connected to the Weld Purge Monitor® via the PurgeNet™ lead.
The dew point sensor is designed to fit any of our Weld Purge Monitors® that read down to 1ppm:
- PurgEye® 200
- PurgEye® Desk
- PurgEye® 600
- PurgEye® 1000
- PurgEye® Site
