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 foaming tendency and stability of oil products such as fire-resistant hydraulic oils, lubricating oils, gear oils, and hydraulic oils, so as to evaluate the foaming tendency and foam stability of lubricating oils.

Instrument Features:

1. Adopts single-chip microcomputer control and PID temperature control tuning technology to achieve fully automatic and precise control;

2. Colorful Chinese and English LCD display, with operation menu prompts and rich dynamic operation prompt information;

3. 4 groups of independent high-precision gas flowmeters to control gas flow, with high precision, stability and reliability;

4. Two constant temperature baths with separate temperature control at 24℃/93.5℃, and an external immersion refrigerator can be installed;

5. 150W high-power vacuum pump to control flow, additionally equipped with a pressure stabilizing regulator, air filter tower, etc.;

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