5E-MAG6700 Automatic Proximate Analyzer (also called thermogravimetric analyzer) is used to determine the moisture ash, volatile matter in coal, coke, biomass, limestone, iron ore, food and feedstuffsby thermogravimetric method. It can also determine residualash and slag combustibles in accordance with ASTM, which is widely applied in power plants, coal mines, metallurgy, food industry, chemical industry, commercial inspection, scientific research, education, etc.
2. Standard Configuration

3. Features
High Stability and Reliablity
a. Dual furnace which could work both simultaneously and independently. Unique isolation board to ensure accurate result of volatile matter.
b. Patented technology of heat-esistant to ensure stability and reliablity.
c. Built-in balance ensures unbeatable accuracy, comply with thermogravimetric method.
d. Unique design to ensure the stability of heating efficiency and temperature keeping.
e. Using black crucible to calibrate the influence of the thermal buoyancy.
Convenient Operation
a. The operator is limited to just adding sample to a crucible.
b. Reference method and customized method available.
c. Capable to load sample continuously and singly.
d. Real time display of balance reading, which makes it convenient to control the precision of sample weight.
Cost Saving
Available for analysis without oxygen and nitrogen by configured air pump, expect for lignite.
Good Safety
Automatically heating off when open the ash furnace cover.
