Analysis of the main performance indicators of laser particle size analyzer

to improveLaser Particle Size TesterThe detection performance has been greatly upgraded and improved by the instrument manufacturer on the optical path system. Most current laser particle size testers can automatically change lenses based on the particle size distribution of the sample, which enables lenses with different focal lengths to correspond to different measurement ranges. This not only effectively improves the measurement range of the instrument, but also eliminates the need for lens heads or optical system adjustments during use, simplifying the operation process and ensuring the stability of the optical path system.
The laser particle size analyzer, which adopts wet dispersion and has physical functions such as ultrasonic high-frequency oscillation and stirring dispersion, can make the agglomerated sample particles uniformly and fully dispersed, thus making the detection results more accurate and reliable. In addition, using a high output centrifugal pump in the circulation system of the particle size analyzer to ensure smooth and stable circulation of particles also greatly helps to ensure high reproducibility of test results. The particle size analyzer equipped with a jet disperser using dry dispersion can utilize high-speed impact airflow to fully disperse the sample particles, thereby ensuring the accuracy of the test results.
　　Laser Particle Size TesterMain performance indicators:
1. Accuracy
Accuracy is one of the most important performance indicators of laser particle size testers. Accuracy, also known as repeatability, refers to the range of error in the results obtained by a particle size analyzer after multiple measurements of the same sample.
2. Range
Range refers to the maximum and minimum particle size range that a particle size analyzer can measure within a single range, reflecting the ability of the analyzer to receive light with the maximum and minimum scattering angles at the same time.
3. Accuracy
Accuracy refers to the error between the measured value and the true value of a particle size analyzer. The smaller the error between the measured value and the true value, the higher the measurement accuracy of the particle size analyzer.
4. Detector
The number of detectors is directly related toLaser Particle Size TesterThe performance. The larger the radius of the laser diffraction ring, the weaker the light intensity, which can easily lead to missed detection of small particles. The increase in the number of detectors can effectively reduce the missed detection of small particles and improve the accuracy of detection results.
