摘要： A harness indicator is highly reactive to a trace amount of Ca2+, and is slow to degrade in a high temperature environment of greater than 50° C. In one embodiment, the hardness indicator contains EBT, a pH buffer, and a masking agent as main components, and an admixture of Mg-EDTA. In another embodiment, the hardness indicator contains EBT, a pH buffer, and a masking agent as main components, and an admixture of anhydrous Mg-EDTA. In another embodiment, the hardness indicator contains EBT, a pH buffer, and a masking agent as main components, and an admixture of anhydrous Mg-EDTA and potassium sorbate. In a further embodiment, the hardness indicator contains EBT, a pH buffer, and a masking agent as main components, and an admixture of Mg-EDTA and potassium sorbate. In a further embodiment, the hardness indicator contains EBT, a pH buffer, and a masking agent as main components, and an admixture of potassium sorbate.

摘要： A liquid feeding apparatus quantitatively feeds a liquid by pressing and clogging an elastic tube between a press roller and an arc-shaped guide portion through rotational motion of the press roller. The liquid feeding apparatus includes a main unit in which the press roller is provided, and a liquid cassette which accommodates a liquid cartridge. One end of the elastic tube is connected to a reservoir for the liquid to be fed, and the other end is connected to a check valve. The liquid cassette is removably fitted to the liquid feeding apparatus so that the elastic tube is subject to pressing action of the press roller.
摘要翻译：液体供给装置通过按压辊的旋转运动将挤压辊和弧形引导部之间的弹性管挤压堵塞来定量地供给液体。液体供给装置包括设置有加压辊的主单元和容纳液体盒的液体盒。弹性管的一端连接到用于待供给的液体的储存器，另一端连接到止回阀。液体盒可移除地装配到液体供给装置，使得弹性管受到压辊的压力作用。
