U-Therm International (H.K.) Limited
this apparatus conforms to the ASTM D482 Standard Test Method for Ash from Petroleum Products,it is used for determination of ash in the range 0.001–0.180 mass %, from distillate and residual fuels, gas turbine fuels, crude oils, lubricating oils, waxes, and other petroleum products, in which any ash-forming materials present are normally considered to be undesirable impurities or contaminants . The apparatus is limited to petroleum products which are free from added ash-forming additives, including certain phosphorus compounds.
