Product description


High automation, high test efficiently

1、Unique automatic sample loader. Operator only need to take it from the loader under room temperature.

2、10 sample positions. Fully automatic, test time less than 3 hours per batch.

3、temperature up to1600℃, applicable to different test atmosphere and samples.


Optimized design, low operation cost.

1、Designed for both coal and biofuel test. Except coal test, we also equip sample making mould and crucible for ash fusion test of biofuel.

2、CE certified high definition camera and radiator reduce heat radiation and realize vivid picture and long service life.

3、Single layer design for graphite cup increase utilization efficiency of graphite and bituminous coal. Test atmosphere in furnace is ensured.

4、Anti-overflow slot in ash cone support can store spilled ash cone and prevent ash cone stick with the plate.

5、Furnace adopts heat resistant and heat insulation material. Imported material for combustion tube and sample boat.

6、Heating element by silicon molybdenum rod, resist to high temperature (max. temperature 1800℃), antioxidation and low aging.


Real time monitoring, precise and accurate result.

1、The whole process of the experiment is monitored and recorded in real time, deformationtemperaturecan be automatically determined by the image processing algorithm of the software.

2、Manual observing and camera recording at same port. Good air tightness and low gas consumption.

3、Gas leakage detection and alarm function make the instrument safe and reliable.


Smart control, easy to operate.

1、Friendly interface, easy operation, real time display of image and data; All data can be stored, printed and uploaded.

2、Windows-based operation system for automated testing.

3、Multi-control with serial communication.

4、Balance connection and data transfer with RS232 serial port.
