Marlborough, MA - This technology combines innovations with robust design features that have been continuously improved through many years of serving customers.

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

According to Doble, this technology combines innovations with robust design features that have been continuously improved through many years of serving 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.
