HK-6538 Automatic Cold Cranking Simulator (CCS) Viscosity Tester

Overview

　　HK-6538 Automatic Cold Cranking Simulator (CCS) Viscosity Tester conforms to ASTM D5293 Standard Test Method for Apparent Viscosity of Engine Oils and Base Stocks Between –5 and –35°C Using Cold-Cranking Simulator. An electric motor drives a rotor that is closely fitted inside a stator. The sapce between the rotor and stator is filled with oil. Test temperature is measured near the stator inner wall and maintained by removing heat with a controlled process to maintain a constant stator temperature during test. The speed of therotor is calibrated as a function of viscosity. Test oil viscosity is determined from this calibration and the measured rotor speed.
