FAQs About  ISO Test Charts

 A gloss test gauges the reflective quality of a surface by casting light at a fixed angle and measuring the amount reflected. It defines the level of shine or dullness of a surface, and it is very crucial in coatings, automotive, and product finishing


A magnetic induction gauge measures galvanized coatings by sensing the zinc coating on steel and iron. The measurement tells how thick the protective coating is. This is done to ensure the prevention of rusting.  


When evaluating the accuracy of a colorimeter, repeatability is a key parameter. 

The repeatability standard deviation ΔE*ab of 3nh colorimeters is within 0.03 (measured under the following conditions: after preheating and calibration, measure the white calibration tile 30 times at 3-second intervals and take the average). This figure is superior to all other similar color measurement instruments. 

Each of our instruments undergoes rigorous factory inspection and calibration before delivery. In addition, 3nh colorimeters are guaranteed to pass the metrological certification issued by official metrology institutes.

When detecting color differences, the first factors to consider when selecting a light source include its stability, directionality, lifespan, and the effectiveness of the ultimately obtained spectral curve. The illuminant of a colorimeter is a fixed bulb, such as a tungsten lamp，LED light or a long-life xenon lamp. However, for the same color sample, the results displayed by the instrument vary under different light sources. This is because different light sources cause different absorption and reflection of light on the sample, leading to differences in how both the human eye and the instrument perceive the color. 

In general, the D65 light source is used in the application of coil steel inks for construction. The D65 light source is equivalent to average daylight. Most coil steel inks for construction are used outdoors, and sunlight is regarded as the standard light source in outdoor environments. For household appliance coil steel inks, due to their usage characteristics, they are mostly used indoors. Therefore, the A standard light source is adopted for color measurement of samples based on indoor lighting conditions. The A light source is a carefully specified tungsten light source. Other light sources, such as fluorescent light sources, can be used in many types of applications. For example, some textile factories use fluorescent light sources. Therefore, a reasonable light source should be selected as the mutually recognized measurement method based on actual usage conditions and user requirements. Once agreed upon by both parties, color measurement must be conducted under the same conditions. This helps reduce unnecessary systematic errors and human errors, achieving the optimal consistency in color measurement. 

The 3nh high-precision spectrophotometric colorimeter adopts a combined LED light source with long lifespan and low power consumption, which includes UV (ultraviolet) and UV-excluded options. This design can meet the color difference detection needs of different users and supports the selection of multiple light source modes.

In the study of chemical reactions, calorimetry deals with changes in heat (energy and enthalpy). Spectrophotometry is the measurement of the light absorbance or light transmittance to determine the concentration or color of a solution. The first one monitors the thermal processes, whereas the second one addresses the aspects of light and color.
