Pinpoint Water Hardness Monitor
(10000 items available)
PINPOINT Conductivity Monitor is an instrument for the measurement of hardness in freshwater. The conversions are 33 S=17.9 ppm=1dH. Good quality reverse osmosis water measures 515 S, while de-ionized water typically measures 01 S. The Conductivity Monitor is automatically temperature-compensated and has two ranges, making it useful for different applications. Both freshwater fish keepers and those who use deionized/reverse osmosis systems often rely heavily on this meter.
