Water Quality Testing & Improving Reagent

Water quality testing and improvement reagents are chemicals and survey sets that can be used for water quality surveys of well water, rivers, and bathtubs. By simply melting the reagent in the collected water, the numerical values of various items such as COD, ammonium nitrogen, and nitrite nitrogen are displayed, which is useful for simple water quality judgment. Sometimes called pack test or drop test, it is also used for river environmental monitoring. It is an item that is colorless and transparent and can be used for continuous observation by assessing water stains that look beautiful at first glance through scientific data.
