Industrial Application of colorimeter and Precautions

What is a colorimeter? What is it used for?
The colorimeter is an instrument used to measure the color difference of objects, which can automatically compare the color difference between the sample plate and the tested object. That is, to make a filter that simulates the light splitting characteristics equivalent to the color sensitivity of the human eye, and use it to measure the light of the sample plate, the key is to design the light splitting sensitivity characteristics of this type of photoreceptor, and be able to measure and display excellent difference values through computer software under a certain light source. According to the principle of Lab and Lch in CIE color space, it can measure and display the color difference △ E and △ Lab values of the sample and the tested sample, and distinguish the subtle differences between colors to achieve the degree of coincidence between colors.

What industries are colorimeter used in?
Metal: used to measure the color of metal surface treatment and metal electroplating.
For example, color measurement of copper nickel chromium layer on steel, silver indium layer on steel, and color detection of iron cabinet
Textiles: textile colorimeter, cloth colorimeter, textile colorimeter, leather colorimeter
Paint: paint colorimeter, spraying colorimeter, coating colorimeter, powder colorimeter
Furniture: furniture colorimeter, paint colorimeter
Automobile: automobile colorimeter, automobile paint colorimeter
Food: tomato paste colorimeter, meat colorimeter, tobacco colorimeter
Ink: ink colorimeter, paper colorimeter, printing colorimeter
Plastic: plastic colorimeter, plastic colorimeter

How to choose the right color difference instrument?
Budget:
According to the actual budget of the company or yourself, whether you want to buy imported or domestic products. If you think you have enough budget and are interested in imported products, you can consider imported products. After all, it is not your fault to have more money! If you are interested in domestic color difference meters, you can also learn more. After so many years of development, the performance of domestic color difference meters is completely comparable to that of imported color difference meters. More importantly, the price is much more favorable than that of imported color difference meters, and the after-sales time of imported color difference meters is long and the cost is high, which is also the reason why more and more enterprises choose domestic color difference meters in recent years.

Performance configuration of colorimeter:
1. You should know which kind of color difference instrument is suitable for your industry. Each industry has different requirements for color difference accuracy, namely △ Eab. If △ Eab is between 0-1, you must choose an instrument with higher accuracy; These are generally rubber and plastic, paint and paint industries; If you do not need high accuracy, you can also choose a general color difference instrument.
2. You need to know the shape of your products. At present, the test aperture of the general colorimeter is 4mm or 8mm; If your product is cambered or the size is very small, you need to consider the problem of test aperture; Of course, it can also be specially ordered as follows:
Large Aperture (LAV): 2.54 cm (1 inch)
Medium Aperture (MAV): 1.5 cm (0.6 in.)
Small Aperture (SAV): 0.75 cm x 1.0 cm (0.3 in x 0.4 in)
VSAV: 0.3 cm x 0.8 cm (0.12 in x 0.31 in)
3. Whether there is national metrological certification. This instrument is a measuring instrument. It is necessary to know whether the product can meet the national measurement requirements. Otherwise, if there is a dispute, your data can not be referenced.
In general, for a color difference meter worth buying, there are many factors worth considering besides the above main factors.
Problems and Solutions of Chromatometer

With battery power supply, the colorimeter cannot be started. What should we do?
1. This phenomenon indicates that the battery power is insufficient and the colorimeter needs to be powered; (Plug in the power adapter or replace the battery)

USB charging port

2. If not, unplug the power adapter and insert it again to check whether it can be turned on, or repeatedly unplug the power adapter for several times.
3. If the above methods do not work, replace the battery.
What should I do if the result measured by the colorimeter is abnormal?
1. This situation is generally caused by no black and white correction or inaccurate black and white correction, and black and white plate correction is required first. Dirt entering the measuring port will also cause inaccurate measurement. It is better to check before measurement;
2. Check if the battery consumption is too low (below 20%), replace it with a new dry battery or use a DC power supply;
3. Check whether the instrument and test object are stable during measurement, and whether the measuring port and measuring surface are in close contact;
4. Check whether the measuring object is too thin and light leaks;
5. Check whether the measuring parts are mixed colors; If the measurement results are still zero after the black and white plate correction, it can be judged that the instrument is broken.

What should we pay attention to when using the colorimeter?
1. This instrument is a precision measuring instrument. During measurement, it is necessary to avoid drastic changes in the external environment of the instrument, such as flickering of ambient light.
2. This instrument is not waterproof and cannot be used in high humidity environment or water mist.
3. Keep the instrument clean, avoid water, dust and other liquid, powder or solid foreign matters entering the measuring aperture and inside the instrument, and avoid impact and collision on the instrument.
4. If the instrument is not used for a long time, remove the battery.
5. The power adapter not specially used by our company cannot be used, otherwise the instrument may be burnt.
6. After using the instrument, put the colorimeter and white board cover into the instrument box and keep them properly.
7. The instrument should be stored in a dry, cool and cool environment. To avoid damage to the instrument.
