SGI-3
Portable oxygen (O2) indicator
Oxygen indicator designed for welders to measure the oxygen in the backshielding gas before and during welding to avoid oxidation and to reduce the purge time/gas consumption.
Measuring range 5000 - 1 ppm O2 in inert gas and CO2, 500 - 10 ppm in inert gas with up to 10 ppm in inert gas with up to 10% H2. 4-20 mA output. Built-in acoustic alarm.
- For oxygen reduction in welding applications with stainless steels and alloys
- For measuring in inert gas with H2 (formier gas)
Features:
- Large measuring range
- Durable ceramic sensor with high accuracy and fast response time
- Self-diagnotics with function alarm
- Selectable pre-programmed calibration settings for inert gas and blends of 2%, 5% and 10% H2
