The refractometer is an indispensable tool for Nutrition Farming®. This simple, robust instrument can utilise just a couple of drops of sap or juice to provide valuable data for crop management. It measures brix levels (total dissolved solids) which give an indication of plant sugars, minerals and vitamin content. The link between high brix levels and inherent pest and disease resistance has been conclusively established. Good brix levels also ensure good taste, longer shelf-life and better yields.
MODE OF ACTION
The solids bend the light as it passes through the sample that is placed on the viewing plate. The amount of bend or degree of rotation due to the sample relates to the reading on the scale seen through the eyepiece.
1.Rinse the glass surface and plastic cover flap with distilled or deionised water and wipe dry.
2.Place a few drops of distilled or deionised water on the glass surface and lower the plastic flap to flatten the water sample evenly over the viewing glass.
3.Look through the eyepiece and rotate the eyepiece to focus the viewing scale.
4.A horizontal line will be visible and should intersect with zero on the viewing scale.
5.If the line passes through the zero, then the unit is measuring zero and is calibrated and ready for use.
6.If the line does not run through the zero, then the plastic cover on the tuning screw should be removed (located on the top of the unit) and the adjusting screw turned either clockwise or anticlockwise to either lift or lower the horizontal line as required using the provided screwdriver.
EXTRA PACKAGING INFO
The refractometer comes in a high-density plastic case lined with contoured foam. Inside the case is a plastic transfer pipette and screwdriver for use when calibrating the instrument.
Store the unit in its case to prevent dust entering the focal tube.
This tool should never be dropped and should always be stored within the shock absorbent foam case when not in use.
Ensure the unit is cleaned and dried between samples and after use.
