Gd-2801g Paraffin Wax Penetrometer

I. Brief Introduction
The instrument is designed and made as per the National Standard of People's Republic of China GB/T4985 "Test Methods for Penetration of Petroleum Wax". The penetration needle and other accessories equipped with the instrument can meet the requirements of GB/T4985.
The penetration of wax is expressed as the depth that a standard needle of 100 g vertically penetrates into a sample without measurable fraction in 5 seconds. It is used to evaluate the hardness of wax.
In general, the testing temperature for wax penetration test is 25 ° C. You can make measurement for needle penetration at a temperature in the range of 25~55 ° C. But you should report the test temperature if it is not 25 ° C.
The unit of wax penetration is 0.1 mm. It can be read directly from the display.
