Набор для тестирования сульфата магния / сульфата натрия

Magnesium Sulphate / Sodium Sulphate Test Set consists of corrosion-resistant stainless-steel immersion baskets, chemical-resistant containers with leak-tight lids, a hydrometer and a thermometer for concentration control, handling tongs that facilitate specimen transfer, and oven-compatible stainless-steel trays. All contact surfaces are smooth, minimizing crystal and fine particle accumulation and ensuring repeatable results in each cycle. Immersion baskets are manufactured from precision-tolerance wire mesh, and the locking lids prevent loss of specimens. The containers are made of chemically stable material suitable for long-term contact with concentrated solutions; leak-tight lids prevent spillage. The hydrometer and glass a thermometer ensure verification of solution density and temperature; gravity graduations are clear and permanent. Oven trays are produced with high flatness; they retain shape during thermal cycles and provide uniform airflow during drying. Handling tongs feature ergonomic gripping surfaces for rapid transfer between sample trays and baskets. The set is sized to meet the geometry and capacity ranges required in the commonly accepted magnesium sulphate soundness and sodium sulphate soundness procedures for aggregate quality evaluation.
