1. Taking a sample


Place 20-50 grams of jam/marmalade in a beaker and mix well with a plastic spoon.

Apply 2-3 drops onto the prism surface.

2.Measuring Method


 ● Hand-Held Refractometers  <MASTER-4α,4T, 4M, 80H>
1) Apply a few drops of jam/marmalade onto the prism and close the daylight plate. Make sure the jam/marmalade is spread evenly over the prism surface.   2) Look through the eyepiece. Read the boundary line where the blue and the white color meet. This is the Brix (%)
*Suitable for jam/marmalade during cooking. The H-Series is best for samples that contain some acids.
*After measuring, wipe the prism with a wet tissue.
 ● "Pocket" Refractometers  PAL2, PAL-3, PAL-α
1) Apply a few drops of jam/marmalade onto the prism surface. To ensure that the sample is covering the prism surface completely, press the sample down with a plastic spoon.   2) Press the "START" key.
Brix (%) value displayed in 3 seconds!
*Wash with lukewarm water after measuring highly viscous samples.

*Low-sugar jam and marmalades have become popular recently. Some products show values between Brix 35-40% which can not be measured by the PAL-2 (Brix 45-93%).
In these cases, we recommend using either the
PAL-1(Brix 0~53%), PAL-α(Brix 0~85%) or PAL-3(Brix 0~95%).
