The salinometer is used to quickly measure the salinity values of liquids and simultaneously display the temperature of the object to be tested. Which is widely used in salt manufacturing, food, beverage and other industrial and agricultural production and scientific research. Features: Double function: to quickly measure the salinity and temperature of the liquid being tested. Salinity measurement: measuring range 0 ~ 199.9ppt, resolution 0.1ppt and accuracy 2% FS. Temperature measurement: measuring range of -50 ~ 70 (-58 ~ 158 ), resolution of 0.1 (0.2 ) and accuracy of 1.0 ( 2 ) , temperature unit / switchable. Reliable quality: intelligent waterproof probe chip with high sensitivity for fast and accurate measurement, and a dual LCD screen clearly displays salinity and temperature. Portable compact design: mini pen type salinity meter, just powered by 4 LR44 button batteries, long-term standby, ideal for carrying and real-time measurement anytime and anywhere. Wide applications: can be used in salt manufacturing, food, beverage and other industrial and agricultural production and scientific research. operation steps: 1. Remove the protective cap. 2. Wash the electrodes in distilled water and dry them with filter paper. 3.Turn on the salinometer. 4.Put the electrode into the liquid to be tested and stir lightly. Wait until the digital is stable, read the final value. 5. Wash the electrode after use and put on the protective cap.
