Automated five Gases plus Moisture Online DGA



The Transfix™ DGA 500 is an on-line monitoring unit that measures five individual dissolved gases and moisture, and provides both on-line monitoring and key exploratory diagnostics. It uses GE’s advanced Photo-acoustic spectroscopy (PAS) technology, made popular due to its accuracy, repeatability and lack of consumable through its bigger brother the Kelman™ Transfix.
