The fully automatic petroleum wax melting point tester is designed and manufactured in accordance with the requirements specified in the national standard GB/T2539-2008 "Determination of Melting Point of Petroleum Waxes—Cooling Curve Method." The instrument can achieve automatic cooling through a refrigeration device, automatic mechanical stirring, automatic display of temperature curves, automatic determination of stagnation periods, and automatic printing of test data. After placing the sample, the operator can start and complete the experiment with a single press of a button.
