Aquasol Pro-Ox 100 Programmable Digital Oxygen Purge Monitor

Precision 100 PPM Oxygen Monitoring with Data Logging & Alarm Features

The PRO OX-100 is a programmable, handheld, self-calibrating oxygen monitor designed for weld purge and inert environments. It reads oxygen levels down to 0.01 % (100 ppm), offers data logging, bilingual display, and is widely trusted for critical applications in TIG, orbital, and pipe welding workflows.

Features:

• Measures oxygen in range 0.00–21.00 % by volume with 0.01 % resolution (100 ppm)

• Self-calibrating or 2-point calibration (ambient air + 99.999 % argon) depending on model version

• Built-in pump samples gas for more accurate measurement in purged environments 

• Data logging: records oxygen levels every 15 seconds (or spot mode), up to 50 data points exportable via USB

• Audiovisual alarm: set a target PPM, with beep + flashing light notifications when threshold exceeded

• Multilingual interface: English, German, Portuguese, Spanish
