Digital Hand-held "PEN" Refractometer
New Continuous Measurment featureto expend your current measuring methods.

(Model No: PEN-PRO)


The PEN-PRO has a measurement range of Brix 0.0 to 85.0% which can be used to measure almost any sample. There are 2 ways to measure with the PEN-PRO. Either dip the tip into the sample and press the START key OR press the START key and touch the tip into the sample. There is also the new feature to perform continuous measurements. The temperature range of the "Dip-Type" Refractometer PEN-PRO has been improved from 60˚C to 100˚C. No more wait ! Measure hot samples while in the cooking process, such as soups and sauces.

The Brix level is the percentage of solids present in the juice of a plant. These solids are mostly made up of sugar and minerals. Just squeeze the item till you get a drop of juice, then use a Refractometer to test it's brix level.

One degree Brix is equal to 1 gram of sucrose in 100 grams of solution, which is equal to 1 % Brix. Therefore, there is no difference between them, in this case 1 ºBrix = 1 % Brix (weight / weight). A Brix meter/Refractometer is the simplest and most accurate tool to measure Brix. The °Brix values are important because they can be measured objectively and they relate to a subjective criterion that buyers and eaters use to assess vegetable quality - flavor or sweetness.


Ergonomically designed for one-handed operation.

Protection class of the PEN is IP65 (Prism head IP67). You can rinse off the sample by running water on the prism. The design allows the user to easily wipe off the sample.

The Automatic Temperature Compensation function of the PEN enable you to take measurement readings regardless of the ambient temperature.

Revolutionary new feature ELI*
*External Light Interference (ELI) - Patent Pending.

Convenient Storage case.

High temperature sample can be measured.
*Do not dip the instrument directly into a boiling pot to measure; instead, place the liquid in a separate container and measure.
