Semi-quantitative Ion Test Paper Iron 1000 to Silver

[Features]
· Semi-quantitative analysis is carried out using the specific reaction between the test paper containing the indicator and the ions in the sample solution, replacing the ion concentration with the degree of color change.
· The coloration portion and the color scale are made the same size in order to facilitate the measurement method, which is to soak the cellulose coloration part that is crimped on to the tip of the PVC stick in the sample solution, and to compare and verify the degree of color change with the color scale pasted on the container.
· Since the test paper is sufficiently long, even harmful sample solutions can be measured safely.
· Dilution is required when the sample solution is of a high concentration exceeding the measurement range, and appropriate removal processing is required when the solution exceeds the measurable pH value or when an interfering ion exists.
