SPRAY-319 Series Spray Particle Size Analyzer Features

1. Exclusive Patent Technology

It adopts representative parallel optical testing technology and Spectrum amplification technique, can realize the wide range expansion in limited space. Besides, it adds several auxiliary integration photoelectric detectors, 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 testing 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

The optical path alignment system can be corrected by one click, avoid adjustment difficulties caused by the optical path movement.

5. Multiple Size Distribution Models

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