SF6 GasCheck P1

SF6 GasCheck P1 – Sensitive SF6 Leak Detector


The SF6 GasCheck P1 is a highly sensitive SF6 gas leak detector capable of detecting leaks to 1×10-8ml/sec (0.1ppm, 0.001 gm/yr).

The revolutionary SF6 gas leak detector utilises award winning negative ion capture (NIC) technology for fast, accurate detection. 

Designed for SF6 gas leak testing and measurement in high voltage electrical SF6 switchgear, the instrument also detects other gases with a high affinity for electrons, such as refrigerant R12.

A unique advantage of the instrument is that it is unaffected by exposure to large leaks. Even after saturation or exposure to leaks of 100%, clear down remains rapid (<1s). The SF6 gas leak detector also benefits from having a non-radioactive source, eliminating registration, storage and transportation issues found with traditional radioactive ECD SF6 gas leak detectors.

Additional features of the SF6 gas leak detector include data-logging, alarms; both audio and visual, and a robust portable case. The instrument requires no consumables, such as Argon, reducing the ongoing costs of operation. There are no items requiring maintenance or service in the handgun or console.

This GasCheck P1 SF6 gas leak detector meets the demands for quality and traceability to International standards as required by today’s industry.
