A Rechargeable 'Eye' on your Weld Purge!
Our innovative PurgEye® 200 Weld Purge Monito ® now with PurgeNet™! The Worlds first and only hand held, rechargeable Oxygen Monitor, measuring accurately from 1,000 ppm (0.1%), down to 1 ppm (0.0001%) oxygen (accurate to 10 ppm). Making several breakthroughs in Weld Purge Monitoring Technology.
NEW Rechargeable Battery Powered Weld Purge Monitor® measuring down to 10 ppm.
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.
Weld Purge Monitor ® invented by HFT ®, who own all Rights and Registered Trademarks in USA and Europe. Designed and manufactured in the UK, for the highest level of quality.

Return on Investment (ROI)
All Argweld® Pipe Weld Purging Systems and all PurgEye® Weld Purge Monitors® provide instant Return on Investment.
Accurately measuring down to 10 ppm
Now with an OLED (organic light emitting diode) display, the PurgEye ® 200 Weld Purge Monitor ® gives sharper, brighter and clearer readings for viewing at longer distances than before. The OLED display is mainly symbol based, which means the menus are easily understandable regardless of which languages the user speaks.
The handy PurgEye ® 200 is battery or mains power driven, with charging carried out from a dock (optional). Battery life is up to 10 hours.
This latest model has a much faster response, long life sensor.
It also has loud, pre-settable audio alarms for rising or falling oxygen levels between 1 and 999 ppm as well as alarm + and – buttons for displaying threshold oxygen settings,
In addition, there is an alarm mute as well as flow detection for accurate reading of gas samples.
The PurgEye ® 200 also comes complete with leak tight connect / disconnect gas hose connections.
For the very first time, the PurgEye ® 200 now features PurgeNet ™, allowing the addition of standard accessories that will allow the Weld Purge Monitor ® to be linked with automatic welding machines such as orbital welders, a traffic light accessory to give visual indication of the Purge process and final a dew point meter.
As with all other HFT products, the Argweld ® PurgEye ® 200 Weld Purge Monitors ® are always in stock and available for immediate delivery Worldwide.

IP65 Rated, Rechargeable and Hand Held
The Argweld ® PurgEye ® 200 is IP65 rated against dust and moisture. It is highly accurate to 10 ppm. The Monitor is lightweight, hand held and rechargeable.
Some of the great features include:
The PurgEye ® 200 now comes complete with PurgeNet™, which controls all 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 to low.
For control of Automatic Welding Equipment by a Weld Purge Monitor®, the relevant cable accessory will be used. At that point, the Monitor will switch off your automatic welding system if by any chance the oxygen level should rise above your pre-set limit, to prevent the risk of weld oxidation. The Monitor will switch the welding system back on, once the excess oxygen has been purged away.
The IP66 Rated (Environmental Protected) PurgeAlarm™ displays a red indicator, only if the PurgEye® has warmed up, the alarm enabled and is reading 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 only if the alarm is active and reading 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.
Rechargeable Battery and Mains Powered
The PurgEye ® 200 can be run by a rechargeable, long life battery lasting up to 10 hours or by 110/240 v mains power. The PurgEye ® 200 is now available with an optional charging dock
The PurgEye ® 200 now has an OLED (organic light emitting diode) display, for brighter, shaper, clearer readings.
If the PurgEye ® 200 is left with an over-range reading for more than 15 minutes, it will automatically turn off to conserve batter power.
The warning alarm can be set to any level between 1 and 999 ppm. The Monitor features both audible and visual indication when the alarm threshold is exceeded.
The flow warning exclamation icon will be displayed whenever the flow of sample gas drops below the minimum flow rate required for an accurate reading. An alert icon indicates where there is insufficient flow of purge gas, which could be caused by a blocked filter.
Power On / Off
If the PurgEye ® 200 IP65 is off, then pressing the standby button will switch it on and it will start the sensor warm-up procedure. Holding the standby button for approximately 10 seconds or until it turns off can turn off the Monitor.
Integral Sampling Pump
With the PurgEye ® 200 switched on and the alarm inactive or muted, pressing the standby button will turn the integral electro-mechanical sample pump on and off.
Settable alarm buttons on the PurgEye ® 200 ensure the desired oxygen ppm level is in place.
The PurgEye ® 200 IP65 Weld Purge Monitor® indicates oxygen levels from 1000 ppm down to 10 ppm (0.001%), so use an Argweld ® PurgEye ® Weld Purge Monitor ® everytime for guaranteed accuracy of oxygen indication to allow a weld start with minimal risk of oxidation.
Technical Data and Specification
