Item: Swelling index tester for coal
Model: FDK-HN6
Features:
Free expansion ordinal analyzer is an instrument for measuring coal coking index by free expansion ordinal method.Crucible type.
It is suitable for use in coal, coking department and scientific research unit.
The instrument uses electric resistance wire as the heat-insulating element with aluminum silicate fiber cotton as the heat preservation material, which has fast heating speed and low energy consumption. 3.The instrument has superior temperature control performance, simple and reliable operation, and unique temperature control method can effectively avoid temperature overshoot and blow the resistance wire. 4.With a focus observation tube, the resulting coke block can be directly compared with the standard group of standard coke blocks with serial numbers.
