Your Questions Answered
The PurgEye® 500 Desk is for in-house/in-factory use for weld purging of welding chambers and enclosures and tube and pipe welding production. It is ideal for applications requiring highly accurate oxygen readings from 1,000 ppm down to 10 ppm, such as welds in titanium, duplex, nickel alloys, and high-spec stainless steels.
The PurgEye® 500 Desk measures down to 1 ppm and is highly accurate down to 10 ppm.
The PurgEye® 500 Desk uses a unique solid-state, long-life sensor that offers faster response times and greater stability in readings.
HFT® has several repair and recalibration facilities worldwide. Contact us, and we’ll refer you to the closest centre.
The PurgEye® 500 Desk has a 1-meter green inlet tube with a replaceable filter.
Each instrument has shielding to prevent most forms of interference. Quality control tests and inspection criteria are designed to account for as many variables as possible, making electrical interference extremely rare.
The Argweld® Weld Purge Monitors® should not be exposed to gas at temperatures above 50ºC (122ºF). Contact us for information on exhaust purge gas cooling methods.
The integral pump extracts the exhausting weld purge gas precisely and draws it across the sensor when there is insufficient flow, ensuring accurate readings.
The OLED (organic light-emitting diode) display provides brighter, clearer, and sharper readings for viewing at greater distances and wider angles. OLED displays are mainly symbol-based, making menus easily understandable regardless of language.

The PurgEye® monitors measure oxygen levels within any gas, not just inert gases. They can be used with argon, helium, nitrogen, and nitrogen/hydrogen mixes.

PurgeNet™ allows a series of accessories to be added to the PurgEye® 500 Desk, enabling control of automatic welding systems based on oxygen levels. It also works with PurgeLog™ Software for data transfer and quality control.

CLIENT TESTIMONIALS

CLIENT TESTIMONIALS

"The purge meters are second to none."

"I am a huge fan of Huntingdon products and have talked to others over the years about using them. The purge meters are second to none. I own and use regularly my PurgEye 100 and my PurgEye 300. I think somewhere, I still have my original Argweld® MKV monitor, which sadly no longer powers up. I am a scarce breed because I have 3 degrees and a complete academic understanding of metallurgy, but more importantly, welding science; I also have over 20 years of hands-on experience in welding on drill floors, firing lines, and vessel shops. I quite literally have a passion for old-fashioned welding! Excellent product, guys!"

"One of the best, if not the best, residual oxygen detector instruments on the market."

"I believe the PurgEye to be one of the best if not the best, residual oxygen detector instruments on the market with its digital residual oxygen level LED display readouts measuring as low as 0.01% and its large, user-friendly viewing screen making it easier for me to read. I also believe the PurgEye has great accuracy in residual oxygen, with speedy measurements displayed within seconds. The PurgEye is a far cry from the old school homemade 'use a cigarette lighter' to check purge gas flow system."

"Purge monitors are a necessity."

"I can personally vouch for purge monitors. When working with medium to large-diameter exotic pipework, they can prevent you from having a terrible day! I've only used the older model, which was a godsend. Anyone, from the welder who has had to carry out weld repairs due to root weld oxidation (or coking) on such materials, to the directors facing an expensive bill for re-work and possible tarnished company reputation, to the client with their project now running behind schedule - knows exactly what I mean. Purge monitors are a necessity."
