| PINPOINT Conductivity Monitor™ is an instrument for the measurement of hardness in freshwater. The conversions are 33 µS=17.9 ppm=1dH. Good quality reverse osmosis water measures 5–15 µS, while de-ionized water typically measures 0–1 µS. The Conductivity Monitor is automatically temperature-compensated and has two ranges, making it useful for several different applications. Both freshwater fish keepers and those who use deionized/reverse osmosis systems often rely heavily on this meter. |
