Industrial Spray Particle Size Analyzer

Overview:

PSA319 is a specially designed and developed bench-top spray laser particle size analyzer for droplet size test. This instrument adopts Fraunhofer diffraction principle and parallel light path design with high-performance and high-power laser, lifetime>25000hours, which can meet the requirements of droplet test. And the test range can be adjusted according to the customers’ requirement.

Application:

PSA319 can be applied to Fire control, forest, pesticide spray test, Medicine nebulizer droplet test, aircraft engine, spray prilling, Nozzle research, any aerosol etc., Therefore especially suits the laboratories of enterprises, colleges and universities and research institutes to use.

 Production Features and Advantages:

1, Exclusive patent technology

It adopts representative Parallel optical testing technology and Spectrum amplification technique and realizes the wide range expansion in limited space. Besides, it adds several Auxiliary integration photoelectric detector, which can effectively collect scattering light from every angle in the testing range, realizing the testing accuracy and reliability in the whole range.

2, Unique Airflow Protection Device

It has airflow protection device, which can effectively protect the lens and avoid droplet pollution to lens in testing process.

3, Split-Type Structure Design

Split-Type structure and adjustable test area can meet the needs of the spray test in any conditions and It has many specialties, such as non-contact measurements, non-interfering etc.

4, Stable automatic optical path alignment system

Remove adjusted difficulty caused by the light path movement, the light path alignment system can be corrected by a key

5, Multiple size distribution model

Free choice standard model, RR distribution and Lognormal distribution. Can convert the volume distribution and individual number distribution freely.

 Test Report and Its Description:

Ⅱ Test Report and Description:

Vx: Particle diameter, < X particle volume summation percent of total particle’s volume  

Nx: Particle diameter, < X particle number summation percent of total numbers of particles

VAD: The volume weighted average particle size.

SMD: Surface area weighted average particle size.

NAD: The number of weighted average particle size.

R.S:  Sample dispersion index, characterization of particle size distribution width. Smaller value, higher concentrated distribution.

N/V: N50/V50, Characterization of particle size distribution width. Values closer to 1, the distribution is more centralized.

Size / quantity distribution: Different statistical analysis
