Thermogravimetric analyzer (TGA)
FC-TGA-S U-Therm International (H.K.) Limited

Application Area

It is applicable in the industry such as electrical power, coal, commerce inspection, environment protection, metallurgy, papermaking, petrochemical, earth probe and the research institute or quality inspecting organization to test the content of air-dry basis moisture, ash, LOI, and Volatile Matter in the coal. The instrument can also automatically calculate Calorific Value and the content of fixed carbon and hydrogen in the samples.

Testing Precision: Ash -- <10%, 0.2%; 10~20%, 0.3%; >20%, 0.4%

Volatile -- <10%, 0.2%; >10%, 0.3%

Inner Moisture -- <3%, 0.2%; >3%, 0.3%

Features

1. Integrated with high precision electronic scale. Using thermogravimetry. Quickly, automatically and continuously tests 11 samples in every experiment. The air-dry basis moisture, ash and Volatile Matter can be tested out in 20 minutes. Automatically tests the Calorific Value, fixed carbon and hydrogen content of the sample.

2. Adopting the unique integrated configuration of "three temperature grade, double furnace", the instrument can work in parallel, and hence to reduce the testing time and the constant temperature area in the furnaces do not interfere with each other. So the testing accuracy of air-dry basis moisture, ash, and Volatile Matter can be ensured.
