Product characteristics
1. specially designed for particle size
measurement of spray, the instrument structure can be changed according
to the application conditions.
2. Fourier lenses with different focal lengths can be interchanged to achieve the conversion of different measurement ranges.
3. The light source uses 2mW 0.6328um He-Ne gas laser emitter, which has
the advantages of good monochromaticity, high coherence, small
divergence angle and strong stability.
4. The patent design of integrated laser transmitter (patent number:
00228952.0) effectively reduces the influence of thermal deformation of
laser tube and external mechanical vibration on the stability of the
instrument.
5. Parallel light path design, variable measurement interval.
6. Including manual fine-tuning and intelligent automatic alignment
function, fast and accurate optical alignment is realized, and the
repeatability of measurement is guaranteed.
7. it can be equipped with a universal 82mmUV lens protection device to
avoid possible contamination of the main optical components of the
instrument, easy to clean and easy to replace.
8. The instrument can be calibrated and validated at any time with the standard sample of circular disc attached randomly.
9. Measuring time and interval can be set to record multiple
measurements continuously, and it has the function of statistical
comparison and analysis.
software function
