Myrkos 2: The Best Portable DGA Analyzer Just Got Better
Utilities can’t afford to wait when transformer health is in question. Dissolved gas analysis (DGA) remains one of the most powerful tools for detecting early warning signs, but results are only valuable if they’re accurate, fast, and accessible in the field.
For years, the Doble Myrkos has set the standard for on-site DGA. Now, with the release of Myrkos 2, the world’s best portable DGA analyzer just got better.
Proven Accuracy You Can Trust
Myrkos 2 continues to deliver what utilities value most: lab-quality results in just minutes, directly at the transformer site. At the heart of this accuracy is the Myrkos 2 ShakeTest™ method, the only technique in the world that extracts gas directly in the oil sampling vessel. By eliminating the transfer step required by other analyzers, ShakeTest™ prevents gas loss and contamination, ensuring more reliable results.
Unlike infrared-based systems that can be skewed by alcohols, acids, or heavy hydrocarbons in the oil, Myrkos is a portable gas chromatograph, the same trusted technology used by DGA laboratories worldwide. Each gas species is separated and measured individually, giving utilities confidence in the data even for older transformers with complex oil chemistry. And it works with all transformer liquid types, mineral oils, silicone, and both natural and synthetic esters. Accuracy is ensured through daily calibration with NIST-traceable gas, a standard practice in leading labs. And with up to nine hours of autonomous battery life, Myrkos 2 is designed for a full day of testing in the field without interruption.
What’s New in Myrkos 2
On top of its trusted accuracy, Myrkos 2 introduces a series of improvements that make it easier and more efficient to use in the field. A redesigned aluminum-alloy calibration gas cylinder now extends shelf life from 18 months to 30 months (2.5 years), reducing replacement needs and lowering maintenance costs. The portable controller has been upgraded with a larger 14-inch display, making results easier to view and analyze on site.
Myrkos 2 is also more portable and durable than ever. All tools, cables, and accessories now fit neatly into a weatherproof rollable case, streamlining transport across substations or between job sites. Improved cable management, a more accessible power switch, and clearly marked stowage for each accessory make setup and teardown simpler and more intuitive. A reinforced mechanical design reduces the risk of damage in transport.
Ease of use extends into the software as well. The updated PPMreport4 platform introduces expanded acceptance criteria that simplify daily calibration while continuing to guide users through every step, from oil sampling to report generation. Together, these updates ensure that field teams can focus on making decisions, not troubleshooting equipment.
Why Myrkos 2 Stands Apart
Compared to competing portable DGA analyzers, Myrkos 2 maintains a distinct edge. Its gas chromatography method provides laboratory-grade sensitivity and accuracy in the field, something infrared-based systems struggle to match. Results are available in as little as two minutes, enabling quick, confident decisions without the delays of sending samples to a lab. For added diagnostic power, Myrkos 2 can also measure oxygen and nitrogen levels with a second ShakeTest™ sample.
Software support further enhances the user experience. PPMreport4 offers guided workflows and customizable reports. Included with Myrkos 2, MyrkosView and InsideView provide intuitive diagnostic tools that help engineers move from data to action. The result is an integrated solution that not only produces the most accurate on-site DGA results but also makes them easy to interpret and share across teams.
The Next Chapter in Transformer Diagnostics
With Myrkos 2, utilities get all the accuracy and sensitivity they’ve come to expect, along with meaningful upgrades in portability, durability, and usability. Field crews can rely on Myrkos for fast, lab-quality insight without waiting for lab confirmation, while utilities benefit from tools that help them make confident, data-driven decisions to protect critical assets.
Because when it comes to transformer health, every minute, and every measurement, matters.
