PurgEye 300 Nano Weld Purge Monitor®

PurgEye 300 Nano

Low Cost
The PurgEye 300 Nano is the industry’s most affordable Weld Purge Monitor® capable of accurately reading O2 levels down to 10 Parts Per Million (PPM). This unit is specifically designed for purging applications involving ultra-high purity stainless steel, titanium, zirconium, and nickel alloy, etc. This no-frills, highly accurate monitor is a simplified version of the PurgEye 300 Weld Purge Monitor™.

New Long Lasting,
Low-Maintenance Sensor The Nano comes equipped with a low maintenance, long lasting integrally mounted sensor shielded against electronic interference. This long life sensor avoids the disadvantages of monitors with outdated “wet cell” technology that require frequent re-calibration and sensor replacements.

Simple Operation
This unit has no pump and no moving parts to fail. It has no knobs, no switches or controls so it is a simple, truly plug and play monitor.
