Lubricating Oils Foaming Characteristics Tester

The instrument is designed and made as per standards GB/T12579 Determination of foaming characteristics of lubricating oils and ASTM D 892 Standard Test Method for Foaming Characteristics of Lubricating Oils. It is used to determine the foaming tendency and stability of lubricating oils.

I. Main technical features

1. This instrument used in a one-piece structure, including three parts: low temperature constant temperature part and control part, high temperature and constant temperature part and control part. Low temperature constant temperature section is equipped with a matching portable refrigerator.

2. Instrument set temperature point after, will be automatically entered into a state of constant temperature. Temperature control with parameter correction function, if the displayed temperature and the temperature of the thermometer measurement deviation, can be modified to achieve the required test temperature.

3. Instrument has automatic timing alarm function, after achieve constant temperature point, open the timer switch, the timer will automatic timing, began to blow at the same time, after 5 minutes, blowing will automatically shut off, and still place 10 minutes, 10 minutes later, the instrument will automatically alarm, said the end of the test sample.
