PAL-HIKARi: Principles of Measurement
What is PAL-HIKARi?
This is an instrument that measures Brix by shining light on the fruit. This graph shows the measurement correlation made between the PAL-HIKARi and refractometer.
4 Features Why PAL-HIKARi is Popular
| Just Place it Against a Fruit
Measuring Brix (sweetness) is straightforward. Place a sensor against fruit and measure. There is no need for wiping and cleaning when it can measure without cutting and juicing. |
 |
 |
Measure Any and All
When you can measure Brix simply by placing the sensor against the fruit’s surface, all fruit can be sampled. Since measuring does not damage fruit, when done, it can be packed and shipped. |
|
So Lightweight that it Can Fit in Your Pocket
PAL-HIKARi is the world’s smallest non-destructive Brix meter. The side button let you measure fruit with one hand while they are still growing on the trees. It is battery-powered so it can be taken and used anywhere. |
 |
 |
A Perfect Fit
The cushion around the sensor provides gentle but firm contact to the fruit’s surface. Regardless of the shape, it prevents external light from interfering and causing measurement discrepancies. |
Other Features
|
Compactness
The light-emitting diodes (LEDs) are used as a light source. Using our cultivated optical engineering knowledge and skills, the path of light to and from fruit was carefully calculated. There is no other portable instrument that can be as easily carried around with you. |

 |
External Light Interference (ELI) Function
PAL-HIKARi is equipped with an ELI function to detect external light that may interfere when measuring outside while fruit are still growing on the tree. When external lights are detected, it will display “nnn”. |
|
2 Easy Ways to Measure
Hold the unit in your hand and press its sensor against the fruit or place the fruit on the sensor. At the push of a button, it will begin taking measurements. Whichever the way you prefer, a buzzing sound will let you know when it is done taking measurements. |

A Cover for Outdoor Usage (Grape & Cherry Tomato)
When taking measurements outside, ’Outdoor Cover S’ is a convenient accessory to use with PAL-HIkARi. |

Measuring Tips
Avoid Gaps!
Make sure that the sample stage has a good contact with the fruit. If they are apart, it won’t take good measurements.
Avoid Broad Daylight!
Let the fruit and instrument adjust to the temperature of your environment. Avoid broad daytime in which temperatures may vary significantly.
Avoid External Light!
When using it outdoors, turn your back against the sun to avoid exposure to direct sunlight.
Questions and Answers
Do I need to prepare fruit in a certain way?
No prepping needed. Measurements can be taken without cutting, filtering or juicing fruit.
Does peel color affect measurements?
No, it does not.
How do I care and store?
Dry the sponge cushions completely. If you plan on storing it for extended period of time, we recommend that you remove the batteries.
Can I measure fruit that are still on the trees?
Fruit can be measured while they are on the trees. Carefully position the cushioned against its surface while making sure the fruit does not fall off the tree.
The measurement varies even when the same sample is measured.
Brix (sweetness) may vary from one spot to another depending on sun exposure and how sugar is stored.
This instrument measures the Brix of a section where the sample stage is placed against.
Which fruit can it measure?
PAL-HIKARi is specific to each fruit. Please see the product lineup here.
I would like to measure jam and other processed food. Which one should I get?
We have the Pocket Refractometer (PAL-0) or sets with Pocket Brix/Acidity meters.
How do I calibrate?
PAL-HIKARi is designed in a way that it does not require calibration.
