Optimus DGA Monitor OPT100

Optimus DGA Monitor OPT100 is available at Industrie Automation Graz, IAG, throughout Austria.

The first maintenance-free multi-gas DGA Monitor requiring no consumables of any kind. Now with a groundbreaking, accurate and reliable method for detecting ambient air leaks into your power transformer — total gas pressure. That’s Optimus™ OPT100.

  • No carrier or calibration gases to monitor or replace
  • No internal column or measurement components to replace
  • No fixed filters/filter wheels, membranes or capillary tubes to repair or replace

Patented. Trusted. Reliable.

Ensure your power transformer stays operational longer. OPT100 brings unmatched long-term stability, reliability and measurement performance. It is trusted for its patented non-dispersive infrared (NDIR) technology, patented vacuum gas extraction technology and its new, groundbreaking total gas pressure measurement to detect air ingress.



  • No More False Alarms - The monitor’s IR sensor is based on Vaisala core measurement technology and critical sensor components manufactured in Vaisala cleanrooms. Vacuum gas extraction means no data fluctuation due to oil temperature, pressure, or type, while the hermetically sealed and protected optics prevent sensor contamination. The end result? A monitor that completely eliminates false alarms.
  • A Monitor That Works Anywhere - Stainless steel pipes, IP66-rated, temperature controlled housing, as well as a magnetic pump and valves provide superb performance and durability – from the arctic to the tropics. There are also no consumables to service or replace.
  • Intelligent Features for Hassle-free Monitoring - The monitor has a web-based interface that completely eliminates the need for additional software, and the device can be installed quickly – just connect the oil, power and data connections, and it’s ready to go. And in case of a disturbance like a power outage, self diagnostics allow the monitor to adjust itself.​
