This Engine Coolant Foaming Tendencies Tester is designed in accordance with ASTM D1881 and SH/T0066, used to determine the foaming tendency and foam stability of engine coolant under specified temperature and air blowing conditions.

This Foaming Tendencies Tester uses glassware to determine the foaming tendency of engine coolant under certain temperature and ventilation conditions controlled by the laboratory. It uses a high temperature resistant glass cylinder as a heating bath to ensure a uniform temperature in the working environment. The instrument is equipped with a special airflow control system to reduce the error caused by manual intervention on the results.
