Product Usage:

The TT-AY series automatic Aoya expansion tester independently developed by our company is a special equipment for measuring coal coking properties. This instrument fully complies with the technical requirements of the national standard GB/T5450-1997 "bituminous coal Oa dilatometer test". The software operating environment is windows10 system. Divided into two models, one is for simultaneous detection of two samples; the other is for simultaneous detection of four samples;

Features:

TT-AY Aoya Expansion Tester is easy to use accurate in temperature control. With a high degree of automation, it is an indispensable coal quality analysis instrument for testing coal content, coal development, production, import export coal coking coal blending.
