American Marine, Inc. PINPOINT Salinity Monitor
American Marine, Inc. (AMI) has an excellent Salinity Monitor. It is precise and easy to use.
AMI claims that its PINPOINT Salinity Monitor will accurately and instantly measure the amount of salt in any marine or freshwater system. AMI also claims that the instrument is easy to set up and calibrate, and that it is durable.
I first calibrated the monitor with the calibration fluid that comes with the product. Then I used it on two different marine systems in my wholesale fish room. I also measured the same water with a plastic moveable-arm hydrometer and a refractometer. I left the PINPOINT Salinity Monitor on one system, so I could check the salinity of that system at any time. More>>
