This test apparatus is used for the determination of the dropping point of lubricating grease. The dropping point is useful to assist in identifying the grease as to type and for establishing and maintaining bench marks for quality control. A grease sample in a grease test cup is supported in a test tube placed in an aluminum block oven at a preset constant temperature. As the temperature increases, at some point a drop of material will fall from the cup to the bottom of the test tube. The reading on the sample thermometer is recorded to the nearest degree as the observed dropping point.
