The Calisto R9 brings something new to the market of DGA monitors: long-term accuracy without calibration gas cylinders to manage. This breakthrough is achieved by combining a novel IR gas measurement technology with a game-changing calibration system that uses water vapor as a calibrant to maintain accuracy over time.

Calisto R9 combines these innovations with robust design features that have been continuously improved through many years of serving Calisto customers around the world. These include membrane extraction to keep the gas measurement system free of oil and oil vapors, our sludge-tolerant pump that eliminates the need for oil filtration, and precision thermal controls for DGA accuracy.
