-The accruacy is superb! I thought my refractometer was accruate but my Salinity Monitor is much better. It gives a reading in mS which can be converted to % of salt or specific gravity using the conversion chart
-Easy to use. All you have to do is to look.
-The reading is fully temperature compensated, which is difficult or impossible with nearly any commercial hydrometer.
-The pinpoint is calibrateable. Make sure you keep the owner manuel for that.
-Unlike pH and ORP probe, it doesn’t need to be stored wet. All you need is to protect the probe from grease and dirt. It is a physical transducer, not a electro-chemical type like the pH or the ORP.
-under good operating condition, it can last longer than a decade.
-It is especially useful to determine the low level of salt required for Koi.
-The probe is easy to clean using a mild soap or vinegar. I clean my probe once a week.
-It “eat” batteries! It can go through a battery within 48h if I leave it on. Those who wants to leave it on 24h/7 can get an AC power supply but I have been told people using this gets constant variation in reading.
Once you have it you’ll never want to be without one.
-Keep it away from water!
