Introduction

Thank you for purchasing the instrument.
Read and follow all safety instructions before operating the instrument.
Fairure to comply with the following instructions may result in personal injury or property damages.
This instrument measures amount of light absorbed by shining the near infared light to the fruit then
converts to Brix (sugar level) to display.
Brix (sugar level) can be measured with no need to cut and squeeze the fruits.
Measurment variance may be seen depending on the variety and harvest timing. This instrument is equipped
with offset function to match the value in such cases.

Safety Precautions

The instrument will turn itself off after 30 seconds of inactivity.
To manually turn it off, hold down the START button for more than 3 seconds.
Depending on the variety, there may be a difference between the refractometer (sugar meter) and the
measured value. Please confirm the difference from the value measured with your refractometer (PAL
- 0 of the set when purchasing IR Brix Meter x Brix Meter) and use the offset function as necessary.

Measurement Tips And Precautions

Acclimate the fruit and this instrument to
●
ambient temperature.
The temperature difference between the
surface and the inside of the fruit, and
temperature difference between this
instrument and the fruit may affect the
measurement values.
Especially when measuring refrigerated fruits,
be sure to let the fruits acclimate to the
ambient temperature.
Clean the surface of the fruits.
●
Do not measure the spoiled spots.
The instrument may not measure correctly
when there is water droplets, dust or scar,
and bruising soft spots.
Place the sample stage to the fruit.
●
Recommended sample size is 15 mm
or more in diameter.
P o s i t i o n t h e
Measure the part where there is no dent with

external light interference. If the silicon
cushion is deteriorated, please replace it with
a brand new silicon cushion. (Refer to"How
to change the silicon cushion")
Sugar level varies depending on the

measured area.
Example for measurement value:
Measure a few berries and use the average
value as the result.
When taking measurements, avoid

changing external light intensity.
If the intensity of external light changes, it
