    PINPOINT ORP Monitor will measure the ORP (oxidation-reduction potential, commonly called REDOX) of your system. It is popular with those who use ozone gas or potassium permanganate as an artificial oxidation agent in fresh or saltwater. Constant monitoring of the ORP is useful in keeping tabs on the overall health of a system, as a drop in ORP often precedes visual or other indications of trouble. This unit features a 1mV digital resolution and a platinum sensor electrode. This is a full range instrument (2000 to +2000 mV)

    PINPOINT Salinity Monitor will accurately and immediately measure the amount of salt in any marine or freshwater system. The reading is fully temperature compensated, which is difficult or impossible with nearly any commercial hydrometer. The conversion chart will precisely show the corresponding density (specific gravity) or % salt (refractometer) values. This monitor is especially useful to determine the low level of salt required for Koi, whether in an aquarium or outdoor pond.

    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.
