The KQ-2 Type Particle Strength Tester is developed and manufactured by Nanjing Kehuan Analytical Instruments Co., Ltd. It features a four-digit display and is equipped with pressure sensors that can be configured for various ranges to measure the compressive strength values of various samples. The instrument has three highlights: one, self-check zeroing function; two, one-button calibration feature; three, over-range protection function (with an alarm). The company has developed its own program, allowing for direct calibration with peak and zero keys, and it has a reasonable structure, manual pressure application, and directly displays the sample strength value during measurement. The instrument is highly precise, compact, and easy to use. It can measure the compressive strength values of single particle samples such as spherical, extruded, and sheet-like solids, catalysts and catalyst carriers, tablets, feed, pharmaceuticals, fertilizers, molecular sieves, grain products, barium carbonate, zinc oxide, rubber additives, carbon black, coated seeds, etc.
