 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 particle size distribution model
Free choice standard model, RR distribution and Lognormal distribution. Can convert the volume distribution and individual number distribution freely.
6, Highly sensitive probes ensure high resolution, instrument can detect the particles's singlas in the real time, uniqe and multiple angle arrangemet ensure small particle's test.
