Scope According to GB/T 5654 and YS-30-1-84 standard, after many years of development and innovation, we have designed to reach the international level, the domestic leading full automatic oil dielectric dissipation tester, it is the ideal product to replace the imported equipment. This instrument is an integrated structure, which is composed of volume resistivity measurement, computer communication systems, oil cup and heating control system of four parts. The instrument adopts a fully enclosed heating, the speed of heating temperature is fast, room temperature is heated to a temperature control and constant temperature automatic measurement only 15 minutes; it can measure the oil dielectric dissipation and volume resistivity or optional.
