Scope for measuring electric power, metallurgy, petrochemical, coal chemical, environmental protection and other sectors of the ash content of coal, coke and other substances. Features 1. Fast: single sample test time can be the result of just 10 minutes. 2, the high degree of automation: just press the computer laboratory personnel program prompts added to the sample, the instrument automatically complete weighing, drying, calculation and report printing, as much as possible to avoid human error and ensure the accuracy of the results, to improve the laboratory personnel efficiency. 3, energy: the use of imported furnace, temperature zone stability, the whole power is only 2KW, heating speed, within 30 minutes you can rise to the experimental temperature 815 ℃. 4, stable performance: the use of modular design effectively reduces the equipment failure rate and improve the operational stability of the machine. 5, TGA weighing technology: modular import balance, when integrated thermal gravimetric analysis technology to ensure accurate weighing test, and fast.
