Product overview
Description
Mobile operation
Designed for locating and quantifying SF6 leaks in GIS, ring main units and gas-insulated equipment during inspection, maintenance and final verification.
Infrared technology
NDIR measurement delivers selective, stable readings. A built-in sampling pump continuously draws gas and responds within 1–5 seconds.
Simple operation
The handheld design and extended probe provide easy access around valves, flanges, joints and difficult inspection points.

View ProductFrequently Asked Questions
Common technical and operational questions about the PGAS-32.
How does NDIR compare with corona discharge detectors?
NDIR selectively measures SF6 by infrared absorption, offering stable readings, minimal cross-sensitivity and a long sensor life without sensor burn-out.
Can the detector show quantitative leak rates?
Yes. The PGAS-32 provides concentration readings in ppm and supports quantitative assessment of leak rates in g/y.
How often is calibration recommended?
Annual calibration is recommended for normal professional use, with shorter intervals for intensive regulatory or quality-control programs.
Is it suitable for outdoor switchyard inspections?
Yes. Its portable enclosure, extended probe and wide operating temperature range support routine field inspection.
