ASTM D4693 Low-Temperature Torque Tester

KN-4693 Low-Temperature Torque Tester 

Overview 

    KN-4693 Low-Temperature Torque Tester conforms to ASTM D4693 Standard Test Method for Low-Temperature Torque of Grease-Lubricated Wheel Bearings. This test method covers the determination of the extent to which a test grease retards the rotation of a specially-manufactured, spring-loaded, automotive-type wheel bearing assembly when subjected to low temperatures. Torque values, calculated from restraining-force determinations, are a measure of the viscos resistance of the grease. This test method was developed with greases giving torques of less than 35N·m at 40℃ 

Features 

1. Adopts double compressor refrigeration, no need to circulate cooling water, uses condenser to dissipate heat, and can be used for cooling when the power is turned on.

2. Adopts the Japanese Fuji digital display temperature controller to control the temperature, and adopts Pt100, which features high sensitivity, high resolution, strong anti-interference, high temperature control accuracy and long service life.

3. The cryogenic chamber of this instrument is sealed well, which ensures that the internal temperature is constant and kept under the temperature required for the test. No frosting.

4. The door part is equipped with a door control switch, and when the door is opened during the test, the internal fan stops working to ensure the safety of the operator.

5. Digital display the test result, and the display unit is mn/m
