Tentacle Tools™ Oxygen Purge Monitor

Tentacle Tools™ Oxygen Purge Monitor

When you’re welding alloy pipe, guessing isn’t an option.

The Tentacle Tools™ Oxygen Purge Monitor is built for welders who need to verify purge quality before the hood goes down. Designed specifically for argon back-purging of alloy and stainless pipe, this monitor gives you a real-time oxygen reading inside the pipe so you know the atmosphere is clean enough to weld—no sugar, no contamination, no rework.

Whether you’re running stainless, duplex, super duplex, or high-nickel alloys, this monitor confirms oxygen levels are within spec before striking an arc, protecting weld integrity and meeting code requirements.

Rugged, simple to use, and made for field conditions—not labs—the Tentacle Tools O2 Monitor helps you purge faster, weld cleaner, and move on with confidence.
