KSJ MG6-F1 gloss meter

Related instruments KSJ gloss meters

For general applications, KSJ MG6-F gloss meter is recommended. Listed below are the key specifications:

  • Angle: single-angle (60°)
  • Range: 0 – 199.9
  • Resolution: 0.1 GU
  • Beam size: 10 mm × 20 mm

More information is available in the following documents:

For more details, please expand one of the blocks below.


The gloss meter uses 1 piece of AA-size battery. The typical battery life is around 58 hours (alkaline battery; without backlight and BlueTooth).

Basic operations

There are just 3 simple steps to perform gloss measurement:

  1. Power on
  2. Calibration
  3. Gloss measurement

1. Power on

Long press the “ON/OFF” button to switch on the gloss meter

2. Calibration

There is a calibration board in the base holder of the gloss meter (shown above). Mount the gloss meter to the base holder and buckle it properly.

Short press the “Calibration” button. While the “CA” symbol is flashing, short press the “Calibration” again. The “CA” symbol disappears and the gloss meter is calibrated.

3. Gloss measurement

Take out the gloss meter from its base plate. Attach the measurement port (at the bottom of the gloss meter) to the surface to be measured. The gloss result is displayed on the screen, without pressing any button.

Good practices

The following good practice practices are recommended:

  • Keep the calibration board and the lens in the measurement port clean.
  • Re-calibrate the gloss meter frequently.
Smartphone controlled gloss measurement

It is possible to perform online gloss measurement with a smartphone (both Android and iOS) via BlueTooth connection and store the gloss measurement results in the smartphone.

Refer to the user’s manual for the details.
