OSM2 Pro
Sampling box for fully automatic, contamination-free extraction of insulating-oil samples directly at the transformer.
- Fully automatic, contamination-free insulating-oil sampling at the transformer
- Complies with DIN EN 60475
- Rugged, mobile box for outdoor use
Water content measurement in insulating oil
WATER CONTENT MEASUREMENTPocket Titrator KF
Precise determination of water content by direct injection of the sample into the measuring cell. The Pocket Titrator KF is a truly portable, easy-to-use coulometric Karl Fischer analyser. Its high-performance microprocessor automatically controls all electrolysis settings – the titration rate adjusts itself to the amount of water to be titrated.
Oil treatment / drying
ES 2000
Whatever oil is in the transformer – water particles in particular lead to rapidly ageing oil and oxidation. The ES 2000 filters in the bypass flow online during transformer operation: it dries the insulating oil, cleans it of particles and residues and reduces the acid content – all without shutting down the transformer.
