440型毛细管吸收时间测定仪可用于垃圾处理设施的控制参数
440型毛细管吸力定时器（CST）由一个数字计时器，样品池，和一个特别选择由单向纤维滤纸。水样本被放置在样品池，导致可变利率水进入滤纸通过毛细管吸力作用。过滤速度取决于颗粒的大小，颗粒含量和沉降速度，絮凝状态。因此，该仪器可用于垃圾处理设施的控制参数和分类及岩土利用土壤类型条件，土壤/膨润土垫的评价，和泥浆槽液和钻井液分析。440型毛细管吸收时间测定仪 CST是理想的在野外使用，它运行在一个单一的9伏电池可提供过40小时的使用。一个电池组是用实验室提供。完整的CST装置包括一个定时器单元，用漏斗法头，9伏的电池和电池组（115伏），一盒滤纸，和指令。 440型毛细管吸收时间测定仪
Capillary Suction Timer (CST) Model 440
Adaptable for use as a control parameter for waste disposal facilities
The Model 440 Capillary Suction Timer (CST) consists of a digital timer, sample cell, and a specially selected filter paper composed of unidirectional fibers. Aqueous samples are placed in the sample cell, resulting in variable rates of water passing into the filter paper through capillary suction action. The rates of filtration are dependent upon particle size, solids content, and settling rates of flocculation state. Thus, the instrument is adaptable for use as a control parameter for waste disposal facilities and for classification and qualification of soil types in geotechnical use, evaluation of soil/bentonite liners, and analysis of slurry trench fluids and drilling fluids.
The CST is ideal for use in the field as it operates on a single 9-volt battery which provides over 40 hours of use. A battery eliminator is supplied for laboratory use. The complete CST device consist of a timer unit, test head assembly with funnel, 9 VDC battery and battery eliminator (115 VAC), one box of filter paper, and instructions.
