4-In-1 Test Meter: Salinity – EC – EDS – Temperature – FREE SHIPPING

The S-100 is a high sensitivity probe for more accurate measurement of salinity (0~9999 ppm/10~200 ppt or 0.0-25%) with an automatic temperature compensation function (32°F~140°F), which can decrease the error caused by the change of liquid temperature.

It also tests TDS (total dissolved solids), EC (electrical conductivity), and temperature in an accurate, quick, and reliable manner for most regular water solutions.

The S-100 features a green backlit LCD to help you see the results clearly in any situation. It auto powers off after 5 minutes of non-use and is IP67 waterproof. The detachable probe and the electrode can be replaced, making maintenance more convenient.

Use it for a wide range of applications including ponds, isolation tanks,  aquariums, marine tank monitoring, pools & spas, koi hydroponics, and more.
