ACCURATE SALINITY LEVELS ALL OVER!
Maintaining the correct salinity level in your aquarium is crucial, and a Salinity Refractometer is an essential tool to achieve this. As salinity is key parameter, it can other parameters if not maintained properly.
 
HOW TO USE
USAGE : 
1.Point the prism (1) towards the direction of light source and adjust the focus tube(4) till the scale line is clear.
2.Calibration : the standard solution(pure water), instrument and sample must be in the same temperature. Open the daylight plate and place 1-2 drops of standard solution on the prism  and slightly press the daylight plate, their shows a light and dark boundary line then turn the calibration screw. The boundary lines and the datum line are coincide 0%.
3. For sample concentration open the daylight plate, clean the surface of the prism with the soft lint and place 1-2 drops of sample on the prism, close the daylight plate and slightly press it. Note down the readings of light and dark boundary’s relative graduations.
4. In the last step wipe off the deposit builder on the prism and surface of the daylight plate with damp lint, dry and place it safe.
