Grandbeing high precision refractometer (0-30°C)
A refractometer is a precision optical instrument that operates on the principle- as the concentration or density of a solution increases, its refractive index changes proportionately. The refractive angle measured by refractometer registers on the scale. The larger the concentration of solute in the solution, the higher the reading on the scale.
Rubber coated hand grip and construction insulates test solution from inaccuracies caused by user’s body heat
Comes with the covered eyepiece and bright, clearly defined scale with large easy-to-read measurements.
For measuring salinity:
Range: 0.0-100ppt, 1.000-1.070sg
