GB/T 508, ASTM D482


This instrument is used to determine the 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.

Main technical features
1. The instrument is composed of amufflefurnace, a temperature controller and an electric heating plate. It is small size and needs less land.
2. The muffle furnace adopts all-in-one structure. Special fire-resistant material and heating components. The heating time is short and it has a long lifetime.
3. An adjustable LED is equipped on the temperature controller is. The overshoot is small and temperature control is stable.
4. The size of heating plate is Φ85mm. Small size and good durability.
