TT-APZ-02 Audibert-Arnu Dilatation Test System
I. Product Introduction:
The TT-APZ-02 series fully automatic Audibert-Arnu dilatation tester independently developed by our company is a special equipment for determining coal caking property. It fully complies with the technical requirements of the national standard GB/T5450-1997 'Test for Audibert-Arnu Dilatation of Bituminous Coal'. The software operating environment is Windows 10 system. It is available in two models: one for testing two coal samples simultaneously, and the other for testing four samples simultaneously. The instrument is easy to operate, safe and reliable, and is the newest instrument for Audibert-Arnu dilatation test of bituminous coal. It is an indispensable coal quality analysis instrument for inspecting coal quality parameters, coal development, production, import and export, and coal blending for coking.
II. Technical Features:
1. The TT-APZ-02 fully automatic Audibert-Arnu dilatation tester is easy to use with accurate temperature control. It has a high degree of automation, automatically calculates the b value of the Audibert-Arnu dilatation index of bituminous coal, and prints the test result report of the Audibert-Arnu dilatation index of bituminous coal.
2. Uniform heating furnace temperature, accurate data, microcomputer high-precision temperature control technology, computer data acquisition and storage.
3. Current and voltage display method: digital
4. Power regulation method: 4-20ma PID control
