Oxygen Analyzers for Ultra-High Purity Gases
PI2-UHP 50/100 and PI2-MS 500/1000
Based on the stable and long-life Pico-Ion oxygen sensors, the PI2 range of trace oxygen analyzers provides accurate and stable measurements of oxygen down to low parts per trillion. Low cost of ownership through minimal maintenance of this high-performance oxygen analyzer make measurement of oxygen down to ppt level easy and affordable for customers with limited budgets.
Product Features
- Measuring trace O2 in ultra-pure Ar, H2, He and N2
- LDL to less than 100 ppt
- Low cost of ownership
- User friendly and easy to operate and maintain
- Fast recovery from process upsets
- Integrated bypass sample system as standard
- Optional auto calibration system with true zero feature via O2 scrubber
