Overview: Salt Tester for personal & commercial use Simple design, easy to carry & operate Uses conductivity test to measure the salt concentration in liquid food Probe: Measure salt concentration Put the probe under the liquid surface by at least 2cm & keep a distance of at least 1-cm from the container wall, when the indicator light is stable, take the highest reading as the measured value Red LED for indicating salt concentration 7 red LED for indicating salt concentrations: 0.3%~0.6% (Moderate);0.8%~1.0% (Thick);1.3%~2.0% (very thick) One green LED power indication ON push button: press the button to power on, then it is ready for measurement. Formula: Salt content= Total quality amp; quantity x concentration Example: Total quality amp; quantity of glass of solution is 150g, and its concentration is 0.5%150g x 0.6%=0.9g Powered by:4pcs LR-44 button cells (not included) Specification:1 x Salt Salinity Tester Analyzer 1 x User Manual Weight Approx:67.7g Size Approx:2.5 x 1.8 x 26.5
