Microrite’s Tracer Particle Generator system provides a cloud of Tracer Particles that are sub-micron (less than 1 micrometer)  in size and are Neutrally Buoyant. These long lasting, Neutrally Buoyant Tracer Particles are ideal for getting a visual representation of air flow patterns in cleanrooms, barrier systems and the interfaces between areas of different classifications (e.g., Grade A/ISO Class 5 and Grade B/ISO Class 7 areas).
