Accurately 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 (µS) 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 µS. Also useful for determining membrane effectiveness of reverse osmosis units. Regular tap water measures about 300-500 µS; good quality RO water measures 5-15 µS.
Protect your American Marine Pinpoint Monitor from damage during transport with optional Armor Hard Carrying Case.
