First, the storage method
• After measurement, wipe off the sample on the prism surface with lens tissue. If the sample contains grease, clean the prism surface with isopropyl alcohol and water (as shown in Figure 1).
• When not in use, store the refractometer in the box and store it at room temperature (0 to 40 ° C). Do not expose it to direct sunlight or moisture in the sun. Do not violently impact or vibrate (as shown in Figure 2).
