Pinpoint Conductivity Monitor

Precision instrument for the measurement of hardness in freshwaterElectronic conductivity monitor measures freshwater impuritiesAccurate way to measure and monitor water quality for aquarium useAccurately measure freshwater impurities. Anything that is not water (like calcium, silica, magnesium, nitrate, etc.), regardless of the amount, will be measured. The Pinpoint Conductivity Monitor is automatically temperature-compensated and has two ranges, making it useful for different applications. Measures in microsiemens (uS) but includes conversion formula for other scales of hardness. Runs on a 9V battery (not included).This precision instrument is perfect for serious discus keepers who add trace elements to pure water to achieve a reading of about 70 uS. Also useful for determining membrane effectiveness of reverse osmosis units. Regular tap water measures about 300-500 uS; good quality RO water measures 5-15 uS.Electrodes, adapter kit, and calibration packets also available.Please click on "More Information" for directions for use.
