The salinity meter is used for fast measuring the EC, TDS, Salinity, and temperature of the liquids. Which widely used in salt manufacturing, food, beverage and other industrial and agricultural production and scientific research. Features: 4-in-1 Practical Salinometer: it can test the EC, TDS, salinity and temperature of the liquid or solution easily and rapidly. Digital Meter: 1.3-inch LCD screen clearly display the tested data, and temperature unit is switchable between Celsius and Fahrenheit. Stable & High Precision: it is composed of sensor, measuring circuit and data proceing device and has automatic temperature compensation(ATC) function to ensure the accuracy of the tested results. Compact Pen Type Meter: ABS materials is lightweight yet durable, easy to operate and carry around. Applications: apply in the aquaponics, greenhouse, hydroponics, floriculture, container grown plants, agriculture, industry, aquaculture, pools.
