Ash Content Tester is a specialized and sophisticated testing unit that determines the remaining ash contents of given samples. The system consists of a muffle furnace, a temperature controller, and an electric heating plate. It is specifically designed for determining ash content in the range of 0.001% to 0.180% by mass in distillate and petroleum products. It is utilized for a wide spectrum of applications, including distillate and residual fuels, gas turbine fuels, crude oils, lubricating oils, waxes, and various petroleum products. This is a critical parameter for a wide range of industries, including food, pharmaceuticals, agriculture, and materials science.
