Refractometer for Salinity Model teropong

The Hand Held Refractometers for salinity are specially designed for measuring the concentration of salt solution. They can be easily used and they are competitive in price. You only need to drop some liquid on the prism and then make it towards to the sunlight. Then the reading of the concentration will appear. ATC means Automatic Temperature Compensation.
