How to measure gloss with using NHG60 gloss meter 

 

Gloss is an important aspect of our visual perception of objects. The perception of gloss can relate to a product’s finish, texture and how a sample is illuminated and viewed. Surfaces with high reflectance are perceived as glossy, shiny or lustrous, whilst less reflective surfaces are perceived as semi-gloss or matt. Gloss can be measured by several different techniques. One of them is by using an optical instrument called a gloss meter. A glossmeter provides quantifiable gloss measurements, expressed as gloss units (GU).

 

The model NHG60 gloss meter is in accordance with IS0 2813(International Standard) and GB/T 9754(China National Standard). The gloss meter features with large tough screen and QC software. It has the characters of easy to use, stable performance and precise measurement. This instrument is powered by built-in Li-ion battery.

Before we use it, we should calibrate it first. 

 

Click “Calibrate” in the main menu, it will remind you to put away the calibration plate. Make sure the calibration plate is installed well on the instrument. Click “OK” or press measure button to start calibration.

 

When operating environment change (such as the rapid change of temperature, altitude and humidity), it must do calibration. In order to ensure the accuracy, please use the original standard plate for calibration. The dust on the standard plate will affect calibration accuracy. Please clean the standard plate and ensure it’s clean when calibrating.

 

The Standard plate is a precise optical component. Please avoid it from strong sunlight. Due to environment factors, the gloss value of standard plate will change over time. Therefore, it’s better to send it back to the factory or qualified local National Institute of Metrology for the calibration. (Once a year) . 

 

After that, we can start to use this model to measure gloss of any sample. 

 

The 60 degree gloss meter NHG60 glossy test instrument has three measurement modes: “Basic Mode”, “Statistical Mode” and “Continuous Mode”.

 

Basic Mode: It is a basic sample test mode which belongs to single measurement. The results will be saved automatically each time. Those data can be used as the standard in Statistic Mode. It can display 5 sets test data simultaneously.

 

Statistical Mode: It has statistical evaluation function and can multi-measure a single sample. If open the difference switch, you can get the results comparing with standard sample.

Continuous Mode: The continuous measuring times can be set to 99 and you can set interval time. When press “Test” button, the instrument starts to measure automatically and will stop measurements according to the settings.

 

If press “Test” button during the test, it will pause or end the current measurement. This mode is used to measure large area samples and evaluate homogeneity of large-area samples.

 

General customers use basic model.
