ALC-25 Determination of attrition index Apparatus is used to measure the resistivity of calcined petroleum coke particles with specific particle size under a certain steady pressure, and also can be used to measure the resistivity of conductive particles such as coke and pitch coke.
Instrument characteristics: This product meets the requirements of ISO10143-1995 and YS/T587.6-2006.
● Special control software and human-machine interface of high-definition touch screen can record and display real-time parameters of test time, sample number, voltage, current and pressure. The system reserves data network transmission function to realize centralized management and real-time sharing of laboratory data.
● Interactive man-machine interface is adopted, which is highly automated and easy to operate.
● Constant voltage control technology ensures the stability of measurement status and good repeatability of measurement results.
● The separate measuring cylinder design is easy to operate.
