The KQ-2 Type Particle Strength Tester is developed and manufactured by Nanjing Keyuan Analytical Instrument Co., Ltd. It features a four-digit display and can be equipped with various pressure sensors for measuring the compressive strength of different sample particles. The instrument boasts three highlights: 1. Self-check zeroing function. 2. One-button calibration feature. 3. Over-range protection function (with an alarm). The instrument is programmed by the company, with peak and zero keys for direct calibration. It has a reasonable structure, manual pressure application, and directly displays the sample strength during measurement. The instrument is highly precise, compact, and very easy to use. It can measure the compressive strength of single particle samples, such as spherical, extruded, and sheet-like particles, catalysts and carrier materials, tablets, feed, pharmaceuticals, fertilizers, molecular sieves, grain products, barium carbonate, zinc oxide, rubber additives, carbon black, coated seeds, and more.
