Lubricating Oil High Temperature Foam Characteristics Tester SD-0722

  • SD-0722


This SD-0722 High temperature lubricant foaming characteristics tester is applied for testing the lubricant foaming characteristics at 150 °C. Heat the sample to 49 °C and  after 30min constant temperature cool it to room temperature. Then transfer the sample to a specified cylinder and heat it up to 150 °C, inlet dry air into the metal diffusion head for 5min. Test the instantaneous static foam amount, kinetic foam amount before stopping air inlet, and static foam amount, foam disappearing time and total volume increase percentage within specific time after stopping air inlet.
