Refractometer saltwater salinity meter

Features:    Small size, light weight, attractive appearance, easy to use. Reliable principle, accuracy to meet the actual needs. The total reflection critical angle method is used to measure the refractive index of the solution, and then the concentration of the measured liquid and its performance are calibrated. Precautions: Do not allow liquids and water to enter the adjustment knob and eyepiece, as this may damage the internal components. Do not drop or collide to avoid damaging the accuracy of the instrument.   Specification:   Salinity: 0-28% Brix: 0-32% Minimum scale: 0.2%   Package includes:    1 x Refractometer 1 x Instruction 1 x Screwdriver 1 x Straw 1 x Flannel   Details pictures:
