By the simple appearance of colour, test papers provide fast conclusions on sample component levels. Designed for specific element or multi-parameter detection, the reagent- or indicator-treated reaction papers give a general content range using graduated intervals. Dip the disposable sticks into the given sample, then match the colour to the provided chart for the most economical and easiest method in quality testing. Having an overall compact size, the test papers can be used on-site.
