Carbon Residue Tester (Rams bottom) LRCT-B20 is used to determine the carbon residue of sample which provides an indication of the deposit-forming tendencies of fuels. It inserts up to five samples the furnace quickly reaches the test temperature ranges from ambient to 550°C. Device contain electric heating method and digital PID temperature controller it adopts to ensure the high precision. It features with digital temperature setting, over temperature control, ceramic band heater with cast iron block, and heavily insulated stainless steel cabinet.
