PINPOINT® Water Hardness 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 Water Hardness Monitor is automatically temperature-compensated and has two ranges, making it useful in several different applications. Both freshwater fish keepers and those who use deionized/reverse osmosis systems often rely heavily on this meter.
The freshwater hobbyist will appreciate the instant readings for precise hardness. The saltwater hobbyist will use the PINPOINT® Water Hardness Monitor to assess the purity of deionized and reverse osmosis water.
- Given proper care, the PINPOINT® Water Hardness Monitor should last a lifetime.
- PINPOINT® Water Hardness Probe is permanent and may never require replacement.
- Powered by a standard 9-volt battery (not included).
