A high-precision Colorimeter is a precision instrument used to measure the color and color difference of objects. It can determine the accuracy of the color of the sample by measuring the reflection or transmission spectrum of the sample, and express the color difference with a numerical value. The following are the key points and precautions for the selection of high-precision Colorimeters:
select points
Measurement mode: High-precision Colorimeters usually have multiple measurement modes, such as transmission mode and reflection mode. Choose the mode that suits your needs.
Measurement accuracy: Different high-precision Colorimeters have different measurement accuracy, and DE (Delta E) value is usually used to express color difference. The smaller the DE value, the higher the measurement accuracy of the instrument. Choose an instrument with a smaller DE value to get more accurate measurement results.
Light source: The light source used by high precision Colorimeter usually has D65, D50 and A etc. D65 and D50 light sources are widely used in color measurement, and A light source is usually used for optical density measurement. Choose a light source that suits your needs.
External light interference: The measurement results of the high-precision Colorimeter will be affected by external light interference, such as sunlight and lights. Choose an instrument with the function of canceling external light interference to get more accurate measurement results.
Data storage: Choose a high-precision Colorimeter with sufficient storage capacity so that you can store and compare measurement data for multiple samples.
Precautions
Standardization: Before using a high-precision Colorimeter for measurement, the instrument needs to be standardized to ensure the accuracy of the measurement results.
Sample processing: Before taking measurements, the samples need to be properly processed, such as cleaning, flattening, etc. Improper sample handling may affect measurement results.
Measurement environment: When using a high-precision Colorimeter for measurement, it needs to be carried out in a stable environment to avoid the influence of factors such as external light source and temperature.
Lighting conditions: When taking measurements, standardized lighting conditions need to be used to ensure the accuracy of the measurement results.
Instrument maintenance: The high-precision Colorimeter needs to be maintained regularly, such as cleaning, standardization, etc., to ensure the normal operation and measurement accuracy of the instrument.
