Test Method
Determines the amount of ash in distillate and residual fuels, gas turbine fuels, crude oils, lubricating oils, waxes, and other petroleum products.


Features and Benefits
  • 6 Complete Air Exchanges per Minute
  • Maximum Temperature of 1100°C
  • Digital PID Temperature Control
  • Store up to 9 different programs
  • Integrated Timer
  • Incoming air preheated for enhanced temperatureuniformity
  • Solid state relays provide for low-noise operation
  • Double walled housing for low external temperaturesand stability
  • Housing made of textured sheets of stainless steel
  • Highly durable, high performance cured vacuum fibermodule lining
  • Ceramic heating plates with integral heating elementwhich is safeguarded against fumes and splashing,and easy to replace
