MYRKOS tiksli dujų chromatografas

MYRKOS DGA

Technical condition very good, tested.

This means that the devices have been calibrated and perform 100% accurate measurements. They are heated regularly for at least 12 hours once a month. It is possible to carry out a transformer oil test on-site—naturally only after pre-checking the sample to enable comparison of results, as shown in the photos.

The MYRKOS chromatograph performs dissolved gas analysis (DGA) in electrical insulating oils. It allows early detection of developing faults in power transformers and other oil-filled apparatus (such as reactors and instrument transformers). It also enables analysis of a gas sample collected from a Buchholz relay!

The MYRKOS chromatograph is highly precise, compact, and offers comprehensive coverage for all significant fault gas concentrations required for oil testing. The gas standard (calibration gas cylinder) ensures measurement consistency with concentration references. Prior to each measurement, the device undergoes calibration and a functionality check. A special shake syringe (included in the set) ensures the correct volume ratio. This is an excellent solution for oil testing laboratories at power plants and research institutes serving the energy sector. The PPMReport software, including a Polish language version, is supplied. Built-in diagnostic tools include the Duval Triangle and Rogers Ratios.

Widely used by utilities, grid operators, and laboratories servicing industrial and professional energy sectors. The field version comes equipped with a dedicated pressurized helium carrier gas container (purity 99.999%). Supplied with shake syringes for preparing the extraction gas phase, as well as syringes for calibration and air sampling.

TECHNICAL PARAMETERS
Number of detectable gases: 9 (Hydrogen H2, Methane CH4, Ethane C2H6, Ethylene C2H4, Acetylene C2H2, Carbon Monoxide CO, Carbon Dioxide CO2, Oxygen O2, Nitrogen N2)
Gas concentration measurement range in oil: H2: 5–60,000 ppm, Other gases: 1–60,000 ppm, O2: 60–100,000 ppm, N2: 500–100,000 ppm

TECHNICAL DESCRIPTION
Gas chromatograph for testing electrical insulating oils by Dissolved Gas Analysis (DGA), suitable for both field and laboratory applications. The laboratory version includes a shaker. The MYRKOS chromatograph analyzes concentrations of dissolved gases in insulating oil (DGA), enabling early detection of developing faults in power transformers and other oil-filled devices (such as reactors and instrument transformers). It can also analyze gas collected from a Buchholz relay. The MYRKOS chromatograph is highly accurate, compact, and ensures complete coverage of critical fault gas concentrations required for oil analysis.

Condition: Very good.

We have two identical, fully operational units available; when purchasing both, the price for one is 50% lower.

Before purchase, I recommend viewing and testing the equipment on-site (conducting a trial). The last test was performed on 21 Nov 2025 and was compared with another MYRKOS unit (verification performed in a certified laboratory).

Available for viewing in Rzeszów.
