SF6 Volume percentage measuring device

For measurement of the volume percentage in air and nitrogen mixtures


This device serves for measuring the gas purity necessary to maintain the dielectric property for arc quenching in circuit breakers. Thanks to the speed of sound measurement developed by DILO results are provided immediately. The microprocessor installed converts the values measured into the SF6 volume percentage.

Easy rinsing after the measuring process – and the device can be used again for another gas compartment immediately.

The device can also be used for measurements of pure SF6 gas or SF6 gas mixtures containing N2 or CF4. Please contact us if you require this device.
