Accurate Refractometer for Laboratory Salt Water Experiment

The RHS-10A handheld Salinity refractometer is used to measure the salt concentration and density in liquids.    It is equipped with two sets of scales: salinity and density values, with specific parameters shown in the table below. The instrument body is made of copper material to maximize measurement accuracy and durability. This model has Automatic Temperature Compensation (ATC). Models without ATC are also available at a lower cost.   Measurement Specifications Scale(s) Range Resolution Accuracy Salinity 0 to 100‰ 1‰ ±1‰ Salt Density 1.000 to 1.070 g/mL 0.001 g/mL ±0.001 g/mL
