Calisto R9 - High-accuracy & low-maintenance dissolved gas analysis (DGA) monitor built for years of service

Calisto R9 is a high-accuracy, low-maintenance online DGA monitor for transformers that measures key fault gases and moisture. It highlights automated water vapor calibration, infrared DIPAS sensing, membrane extraction, a sludge-tolerant pump, secure design standards, intuitive browser-based UI, and SCADA-friendly communication protocols.

Product Overview

• High-accuracy infrared DGA monitor measuring key gases and moisture reliably.
• On-board automatic calibration uses water vapor, eliminating calibration gas cylinders.
• DIPAS and thermal conductivity enable fault detection and accurate diagnosis.
• Robust design includes membrane extraction, sludge-tolerant pump, secure communications protocols.

Calisto R9 delivers long-term DGA accuracy without calibration gas cylinders. Its infrared DIPAS measurements and thermal conductivity for hydrogen provide sensitive, stable results across key fault gases and moisture. Membrane extraction, sludge-tolerant pumping, and an intelligent bubble trap simplify installation and operation, while industry-standard protocols integrate seamlessly with existing SCADA.

Target Market

Ideal for utility transmission and distribution organizations, industrial facilities with large power transformers, and service providers. Primary users include asset managers, substation engineers, protection engineers, and reliability/condition monitoring teams seeking early fault detection, accurate diagnostics, and low-maintenance online transformer health monitoring.
