The MFS/1 is an oven specifically designed to determine the moisture content of coal. MFS stands for Minimum Free Space, with the oven having a miniature chamber that follows standards for drying coal. The established coal mass is inserted into the chamber at a temperature between 105°C and 110°C under a flow of Nitrogen ISO model or Air ASTM model until the mass remains constant. The difference in mass after the heating process determines the moisture content.
There are two models: MFS/1/ISO meets the standards BS 1016-104.2:1991, BS ISO 687:2010, and BS ISO 11722:2013, and MFS/1 ASTM complies with ASTM D3173-11.
MFS ovens have a volume of 1.4 litres, an exact chamber size of H 25 x W 195 x D 290 mm, and a height reduced to 22 mm directly below the thermocouple. The maximum operating temperature is 210°C, with uniformity and stability at plus or minus 0.5°C.
The MFS/1 ISO uses Nitrogen to remove coal moisture, which is supplied by a regulated bottle. S/1 ASTM operates with a regulated flow of air.
