ADTR-2K Automatic Dielectric Constant, Tan Delta & Resistivity Test Set

The Automatic Dielectric Constant, Tan delta &Resistivity Test set, (Model ADTR) is an instrument designed to measure three important parameters of an insulating medium.

• measurement of the tangent of the angle of dielectric losses, dielectric constant and specific volumetric electric resistance of transformer oil
• measuring cylindrical vessel, three electrode type
• complete automation of measurement according to DSTU 6581-75, IEC-60247-2004, ASTM-D924-03, AS-1767.1-1999, BS-148-1998, JIS-C2101-1999, ASTM-D1169-02, IEC 61620
