To measure moisture in oil with a hand-held, user-friendly instrument requires extraordinary measurement technology. The hand-held meter OILPORT 20 meets these multiple demands and is available with a pressure-tight or short measuring probe. The robust housing of the OILPORT 20 allows usage in harsh industrial environments. The physical quantities measured are water activity aw and temperature T. With these quantities OILPORT 20 SET calculates the water content (ppm) in mineral transformer oils. Calculation of water content in non-mineral transformer oils and parameters of the oil. The carrying cases can accommodate the measuring equipment with optional calibration devices. The accuracies of the measured values are traceable to international standards, administrated by NIST, PTB, BEV...
