Note: The parcel will be sent without battery ,The battery type is 2 pcs AAA battery About products The AMSZ-Y digital display salinity meter is a digital display high-precision optical instrument designed using the principle of refraction. It is small and beautiful, easy to use, and has a large LCD digital display. As long as a drop of sample solution is placed on the prism, the measured value will be displayed within 3 seconds, which can avoid subjectively erroneous numerical interpretation. Professionally used in various pickles, kimchi, pickled vegetables, salted food, marine biological feeding, aquarium, physiological saline preparation and other fields. Characteristic & Function 1 Automatic temperature compensation function. 2 Battery-powered, low power consumption, no operation automatic shutdown function within 2 minutes. 3 Refractive index/salinity conversion. 4 No moving parts, high sensitivity and wide dynamic linear range. 5 The amount of samples and reagents is small, and the analysis speed is fast.
