DOMINO USS
Portable Water in Oil and Dewpoint Analyzer
MONITOR LEVELS AND The Doble DOMINO USS (Ultimate Sampling System) gives you a fast, efficient way
to measure water content in oil and/or the dewpoint of a gas. The DOMINO USS is a
CHANGES IN WATER IN portable system that connects quickly and easily to transformer valves or other oil-
OIL MEASUREMENTS filled electric devices. Operating on AC power supply or with its rechargeable battery,
you will have accurate readings quickly. The DOMINO USS is customizable to your
IN REAL TIME testing requirements, coming with either a water in oil test sensor, a water in gas
(dewpoint) test sensor, or both.
FEATURES
• Get accurate results quickly
• Analyze different oil types: new and in-service transformer oil, very
aged transformer oil (>0.18 mg KOH/g), silicone and natural esters
(vegetable oil dielectrics)
• Sensor can quickly be connected to a transformer valve or other oil-
filled electric device for readouts of water content in ppm
• Sensor is immune to oil vapor
BENEFITS
• Maximize testing time by taking high quality samples during field
testing
• Modular, multi-option structure allows you to begin with a basic kit
and add to it as your needs evolve
• With special features to monitor transformer installation you can:
» Monitor the dewpoint of the interior atmosphere of the
incoming transformer
» Monitor the dewpoint of vacuum, dry air, nitrogen and
other inert gases
» Monitor the oil filling process by measuring the incoming
and outgoing oil from the processing trailer
