共立理化

自成立以来，共立理化研究所一直专注于“水质的简单分析”领域，重视该领域的声音。

尤其是我们的代表产品Packtest ® 作为最简单的水质测量仪器，作为任何人都可以在任何地方使用的水质测量仪器，发展成为迄今为止受到广泛支持的产品。

包装测试时，将为每个测定项目准备的试剂密封在聚乙烯管中，使用时将管尖端的线拉出，吸入一定量的待测水。与滴管相同的方式。将在规定时间后反应的管中液体的颜色与标准颜色进行比较。最接近标准颜色的颜色值就是您要测量的组分的测量值（mg/L）。

Since its establishment, Gongli Institute of physics and chemistry has been focusing on the field of "simple analysis of water quality" and paying attention to the voice of this field.
Especially our representative product packtest ®  As the simplest water quality measuring instrument, as a water quality measuring instrument that anyone can use anywhere, it has developed into a widely supported product so far.

During the packaging test, the reagent prepared for each measurement item shall be sealed in the polyethylene pipe. When in use, the line at the tip of the pipe shall be pulled out and a certain amount of water to be measured shall be inhaled. In the same way as a dropper. Compare the color of the liquid in the tube reacting after the specified time with the standard color. The color value closest to the standard color is the measured value of the component you want to measure (mg / L).
