PDGA.1000 Portable Dissolved Gas Analyzer

The PDGA.1000 Portable Dissolved Gas Analyzer represents a new generation of dissolved gas analysis equipment. Using infrared photoacoustic spectroscopy technology, it delivers rapid, accurate, and reliable results directly in the field—providing concentrations of 7 key fault gases and moisture within 20 minutes.

This makes the PDGA.1000 a practical alternative to traditional laboratory gas chromatography systems and an essential tool for transformer and oil-filled equipment diagnostics, including power transformers, tap changers, circuit breakers, and Buchholz relays.
