Analysis Instrument for Determining the Gas Humidity in SF Gas - GA20
Description
The analysis instrument model GA20 is used for determining the humidity content in SF6 gas. Due to the procedures of filling and servicing equipment, a residual humidity in SF6 gas is inevitable.
However, humidity must be kept as low as possible for guaranteeing a faultless long-term usage.
Features- Fast test results, measuring time approx. 5 minutes.
- Compact and low weight.
- Maintenance-free.
- Operation via touchscreen.
- Long battery life.
