Optimus™ DGA Monitor OPT100

The world’s first maintenance-free multi-gas DGA monitor now comes with the groundbreaking, robustly reliable  total gas pressure method for detecting ambient air leaks into your sealed power transformer. That’s robust technology enabled by Vaisala science — that’s Optimus™ OPT100.

No consumables of any kind required. 

  • 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 for detection of any formation of fault gases. It is trusted for its patented infrared  measurement of DGA gases, unique vacuum gas extraction technology and its groundbreaking total gas pressure measurement to detect air ingress into a sealed transformer tank. 

A word from our customers

 “Over two years after installation we have had no problems with the equipment at all – no user intervention and no consumables have ever been needed.”
- Eduardo Briosso, Asset Maintenance Manager at CTM.

“We have compared the data from the OPT100 with our third-party professional offshore testing report and it has proven to be very accurate, so we know we can rely on its performance.”
- A person in charge at Dalian Company.

“The OPT100 gives us the ability to track any disturbance that may occur and extend the lifetime of our transformer, as well as reducing the possibility of any unplanned outages.”
- Keith Black, System Performance Senior Engineer at Scottish Power.
