Description: Clear LCD display for fast reading to test salinity and temperature of liquid. Salt concentration Measurement Range 0.3%~0.6%；0.8%~1.0%；1.3%~2.0%, 0.1% Resolution. Simple design, easy to carry and operate. LED indicator display. Conductivity test method to determine the concentration of salt in liquid foods. Place the probe at least 2 seonds on the surface of the liquid and the result will appear. The red light indicates the salt concentration, the green light indicates the power. Suitable for freshwater aquaculture, freshwater aquariums, marine aquaculture, seawater, brine, soup, liquid food salinity testing. Specification: Power input: 4×1.5=6V LR44×4 Working current: MAX 20mA (full LED) Size: 212×24.8×15.4 (mm) Weight: about 36 grams Measurement range: 0.3% ~ 2.0% Applicable temperature range: 60℃ ~ 80℃ Formula: salt content = total mass × concentration Material: Plastic Color: White Size: approx. 212x24.8x15.4mm/8.35x0.98x0.61inch. Package Includes: 1 Piece Salinity Meter 1 Piece User manaual Note: Press the switch of salt content tester ON to see the Power indicator light is green. If it is not bright, it means the battery voltage is too low and a new battery is needed. Insert the salt content tester probe into the solution at least 2CM and test it at least 1CM away from the container wall. Read out the last reading of the red light after the display is stable, then the test value is. After the test, clean the part of the probe with a neutral cleaner. Clean the probe part of the machine with clean water or with cloth with neutral detergent Do not clean the main part of the machine with clean water or cloth with neutral detergent Do not use , diluent or gasoline to clean the probe and body parts of the machine.
