Gauge to check whether the ceramic filter of the Drip Ceradyn/Gravidyn filter needs to be replaced.
Dasspan style="white-space: pre; "The Drip measuring device is a mass gauge. You can use it to determine whether the ceramic filter elements of the Katadyn Drip Ceradyn and Gravidyn need to be replaced. The ceramic depth filters remove bacteria, protozoa and other pathogens according to a simple principle: the mini-pores of the filter ceramic are smaller than the microorganisms mentioned. Depending on the degree of contamination of the water, these pores become clogged and the filter element must be cleaned mechanically. The best way to do this is to rinse it with a swimming pool until the bright, original color reappears. Each filter element loses a little material with each cleaning. The mass gauge indicates whether a filter element is used up and needs to be replaced. It's very simple: if the gauge passes over a filter element, the filter must be replaced.
