Overview
Enviro Testers Portable Oxygen Purity Analyzer can be used to measure the trace oxygen concentration in the fields of nitrogen separation from air, chemical process, magnetic materials such as high temperature sintering furnace gas protection, the electronics industry protective gas, glass & building materials industries, various mixed gases, etc.
Features
- Advanced electrochemical oxygen sensor for long life and high precision
- Measures oxygen concentration in H2 or deoxidized gas
- Inner special gas-route protects the sensor when exposed to air
- Concise menu and simple operation
- Automatic temperature compensation
- Full-charged battery can be used continuously for about 8 hours
- Inner air pump (optional)
