A:Product  Introduction:
　 DSHD-3554 Petroleum Wax Oil Content Tester is designed and made as per the National Standard of People's Republic of China GB/T3554 "Test Methods for Oil Content of Petroleum Wax".

DSHD-3554 Petroleum Wax Oil Content Tester is suitable to determine the oil content of petroleum wax,  the congealing point of which is higher than 30 °C and the oil content of which is not more than 15%.

Specific operation is as follows: Solve sample in the methyl ethyl ketone and cool it to -32 °C to separate wax out. Filter it and evaporate methyl ethyl ketone in the filtering liquid. Weigh the residue and calculate the oil content in the wax.
　  DSHD-3554 Petroleum Wax Oil Content Tester is worth noting that For some wax having oil content higher than 5%,  if the oil could not be completed dissolved in the methyl ethyl ketone,  please don't use this instrument.
