Redefining Trace Oxygen Measurement

Our ultra-trace oxygen analyzer delivers exceptional stability, accuracy, and uptime at the lowest detection levels, while minimizing maintenance and operator intervention. Automated electrolyte replenishment enables reliable ppb-level measurements over extended periods, keeping continuous processes running without interruption. This performance is driven by a patent-pending, purged-cathode, non-depleting coulometric sensor. To ensure complete confidence in every reading, an optional embedded sonic-orifice dilution system provides true trace-level calibration, eliminating ppm-level extrapolation errors and delivering accurate calibration directly at just a few ppb.

Features

Ultra-trace precision

True zero stability with our purged-cathode design (patent pending) that blocks ambient O2 ingress.
Purged gas can be generated internally from sample gas of from external source.
Uncompromising measurement accuracy with built-in optional sonic-orifice calibration system for true ppb calibration and a purged electronics flow controller.
UHP sample integrity guaranteed with a leak-free strem-selection system using CVProducts (an ASDevices division) patented purged PLSV valve.

Low maintenance

No weekly checks, no top-ups: a built-in dionized water (DI) reservoir with automatic level control enables year-long, worry-free operation.
Non-depleting sensor technology for long life and stable performance.
Auto-calibration maintains accuracy while minimizing operator intervention.

Ease of use

Clean, spill-free electrolyte changes thanks to a dual-valve design that keeps the sensor untouched.
