gaz sf6-Purity-Meter - GA50 - WIKA India

Description. The WIKA SF 6 -Purity Meter is a cost effective way to determine if the SF 6 percentage in SF 6 -filled equipment meets the requirements. Tolerable limits are suggested by the cigré SF 6 -Recycling Guide and the IEC 60480 for used gas. Measuring the SF 6 -concentration the SF 6 -Purity-Meter indirectly measures impurities of the tested SF 6 -gas like air and CF4.
