SGI-3
Portable oxygen (O2) indicator
Oxygen indicator designed for TIG 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 TIG welders
- For measuring in inert gas with H2 (formier gas)
Features:
- Large measuring range
- 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
