    • A disposable meter for testing the level of total dissolved solids in a water source and a method of testing the concentration of total dissolved solids are herein disclosed. The disposable meter may include a body with at least water resistant properties, a first indicator, the energization of which is indicative of a threshold level measured total dissolved solids, a pair of electrodes wherein energization passing between the pair of electrodes completes a circuit, and circuitry disposed within the body connected to the first indicator and the pair of electrodes. The circuitry may be configured to commence energization to pass between the pair of electrodes, measure the conductivity of the water between the pair of electrodes, and energize the first indicator if the measured conductivity value exceeds a predetermined threshold value. The method of testing the concentration of total dissolved solids present in a water supply may include projecting a current between a first electrode and a second electrode, measuring the conductivity of the water between the electrodes, comparing the measured conductivity to a plurality of threshold values, and energizing an indicator in a matter that is correlated to the highest threshold value met by the measured conductivity.
    • 本文公开了一种用于测试水源中的总溶解固体水平的一次性仪表和测试总溶解固体浓度的方法。 一次性计量器可以包括具有至少防水性质的本体,第一指示器,其通电指示测量的总溶解固体的阈值水平,一对电极,其中通过该对电极之间的通电完成电路,以及 设置在主体内的电路连接到第一指示器和一对电极。 电路可以被配置为开始通电,在一对电极之间通过,测量一对电极之间的水的电导率,并且如果测量的电导率值超过预定阈值,则激励第一指示器。 测试供水中存在的总溶解固体的浓度的方法可以包括在第一电极和第二电极之间投射电流,测量电极之间的水的电导率,将测得的电导率与多个阈值进行比较, 并且通过与所测量的电导率所满足的最高阈值相关的事件激励指示符。
