This instrument is designed and manufactured in accordance with the requirements specified in the national standard GB/T 12579 “Determination Method for Foam Characteristics of Lubricating Oils”. It is used to determine the tendency and stability of foam formation in oils such as fire-resistant hydraulic oils, lubricating oils, gear oils, and hydraulic oils, so as to evaluate the tendency of lubricating oils to form foam and the stability of the foam.

Instrument Features:

1. Adopting a temperature control instrument with fast heating and high temperature control accuracy, with a temperature control accuracy of ±0.1℃;

2. Two constant temperature baths at 24℃/93.5℃ with separate temperature control, and an external immersion cooler can be used;

3. 4 sets of high-precision gas flow meters to control gas flow, with high precision, stability and reliability;

4. Equipped with an air pump, a pressure stabilizing regulator, an air filter tower and 4 independent air flow meters;

5. Internal components such as heaters and stirring paddles are made of stainless steel, which is corrosion-resistant and durable;
