The customized Brightness meter factory is one of the commonly used instruments and equipment required by every chemical analysis laboratory, and has been widely used in various quantitative and qualitative analysis. So do you know what its principles and characteristics are? Let’s take a look at it with the editor below!
1. Principle
The customized Brightness meter factory mainly uses a pair of light holes with a certain distance to receive the luminous flux of a fixed solid angle and a fixed projection area. This value does not change with the distance of the object, as long as the surface area of ​​the object is large enough. In order to aim at the measured object, an imaging system is often used. The light source to be tested is imaged on the mirror with a hole (front light hole) after passing through the objective lens, and a part of it is received by the human eye through the mirror and eyepiece to aim and monitor the coincidence of the clear imaging surface with the mirror with the hole; the other part of the light is Go through the small hole on the reflector and reach the V(λ) receiver through the rear light hole. The brightness value is displayed by pointer or digital meter.
2. Features
1. Using microcomputer control and data processing.
2. The interference filter is used as the light splitting element, and the photoelectric tube is used for photoelectric conversion.
3. With direct reading of potassium and sodium concentration, curve fitting, sensitivity drift, automatic correction, and automatic full scale adjustment. Operation error display, printing results and other functions.
4. Linear stability, good reproducibility, especially suitable for clinical applications.
In summary, it is an introduction to the principles and characteristics of the customized Brightness meter factory. You can learn more about it through the above introduction.
