Product Introduction

The purpose of this product is to provide a fitting connection for the automatic calibration or replacement of the SF6 gas density relay in SF6 electrical equipment. It is important that the inflation port, micro-water test port, calibration port, and gas shutoff port of this fitting connection are all the same, eliminating the need for additional inflation and micro-water test ports. This allows for both inflation and micro-water testing of the SF6 electrical equipment and calibration of the SF6 gas circuit to the density relay at the same location without extra interfaces.
