VisiSize P15+
Portable Particle Size Analyser for Droplet Sizing and Spray Characterisation
VisiSize P15+
The most compact of the VisiSize range of particle sizing systems, the portable VisiSize P15+ is a complete, integrated droplet size measurement tool for real-time spray analysis in the field or in the lab.
The VisiSize P15+ is a compact, portable particle size analyser providing lab-quality, comprehensive droplet and particle sizing analysis in real time. Featuring a simple ‘Plug in and Play’ design, the VisiSize P15+ is a fast, effective method of measuring droplet size, shape and velocity to quickly understand spray quality. The tool is designed for easy set up and can be rapidly deployed in the field or in the lab. The VisiSize P15+ enables you to start collecting your first data in less than five minutes.
This one-piece, sealed waterproof enclosure is rated IP67 which allows the system to be placed in the spray. As a field-ready particle size analyser, the system provides accurate particle and droplet diameter distribution data. The system also provides close up images of the spray formation and break-up process. This adds a very powerful capability for research and troubleshooting applications which is not available from any other droplet sizing system.

FAQs - VisiSize P15+ Droplet and Particle Size Analyzer for Spray Characterisation
What does an imaging droplet particle sizing system measure?
An imaging system captures photographs of individual droplets or particles in a spray, aerosol or particle stream, measuring their size, shape and velocity simultaneously. VisiSize systems do this in real time, so you can see and verify exactly what you’re measuring rather than relying on an inferred distribution.
Why choose VisiSize systems for droplet and particle sizing of your sprays?
VisiSize droplet and particle sizing analysers are powerful tools for real-time flow visualisation and spray measurements without additional processing, the need for frequent calibration or lengthy set up time. VisiSize is purpose-built for particle and droplet sizing, combining size, shape and velocity in a single automated measurement with an easy and fast-set up time to produce valuable data in the field or in the lab.
What applications is imaging droplet and particle sizing used for?
Agrochemical spray characterisation, fuel and combustion sprays, inhaled drug delivery, fire suppression droplet measurement, consumer product atomisation measurements, food manufacturing with sprayed coating processes, automobile paint droplet measurements, industrial nozzle development and atmospheric research — anywhere droplet or particle size and velocity affect performance. Read the full list.
Can I see the system before committing?
Yes. Our applications team offers demonstrations and can run sample measurements for your specific application. Contact us to arrange a consultation.
