คุณลักษณะ

• Semiquantitative determination is performed using a specific reaction between a test paper containing a coloring agent and ions in the sample solution.
• To measure, simply dip the test paper into the test solution and compare the degree of discoloration with the color scale on the outer box.
• The samples are good in small amounts and the ion selectivity is very good.
• The test paper stuck to the end of the plastic stick (0.2 mm thick) is the same size as the color scale and makes color comparisons very clear.
