在混凝土生产和施工中,准确掌握和控制水的用量是决定混凝土质量及其一系列性能的关键因素。在施工现场、商品混凝土和预制工厂,大中型水电工程中,砂的含水率往往是个随机因素,其波动范围广达1～15％,因此如何迅速准确测定砂的含水率,特别是对利用微处理机进行混凝土生产自动控制或质量管理部门,尤为重要。SM—1型砂含水率测定仪是利用电容法的原理,进行这种测量的专用
Accurately mastering and controlling the amount of water used in concrete production and construction is a key factor in determining concrete quality and a range of properties. In construction sites, commercial concrete and prefabricated factories, large and medium-sized hydropower projects, the moisture content of sand is often a random factor, and its fluctuation range is as wide as 1 to 15%. Therefore, how to quickly and accurately determine the moisture content of sand, especially for micro- It is particularly important for processors to perform automatic control or quality management of concrete production. The SM-1 Sand Moisture Analyzer is based on the principle of the capacitance method and is dedicated to this type of measurement.
