Lube Oil Foaming Characteristics Tester BLS-892
【Brief】:The instrument complies to ASTM D892, IP145 and GB/T 12579.
【Series】:Lube Oil Testers


The instrument is designed and manufactured according to ASTM D892, IP145 and the requirements of the People's Republic of China standard GB/T 12579 Lubricating Oil Foam Properties Determination Method. It is suitable to determine the foam properties of lubricating oil  and measure the foaming tendency of the lube oil and the stability of the foam.


1.Adopts integrated structure, including three parts: the low temperature constant temperature part and its control part, and the high temperature constant temperature part and its control part. The low temperature constant temperature part is equipped with portable cooler.

2. After the constant temperature point has been set, the instrument will enter into constant temperature state automatically. The temperature controller is equipped with parameter correction function. If the displayed temperature deviates from the temperature measured by the thermometer, the required temperature can be achieved through correction.

3. The instrument has automatic timing and alarm function. When turn on the timing switch after reaches the constant temperature point, the timer will automatically time and start to blow at the same time. 5 minutes later,the air will be automatically turned off and kept static for 10 minutes. 10 minutes later, the instrument will alarm automatically to indicate that the current sample test is over.
