The AvCount3 is a compact bench-top automatic particle counter, used to measure the size and distribution of particles and water droplets in light and middle distillate fuels, including aviation fuel and kerosine, biodiesel, low viscosity oils and hydraulic oils.

Featuring a simple user interface with touch screen display, the fully-automated test means extensive operator training is not required before using the instrument. The simplicity of test set up and automation, gives operators the time to work on something else, helping to reduce labour costs.

The AvCount3's enhanced functionality includes a dilution protocol for testing of high viscosity samples, real-time display of test progess, 14 embedded test methods, user and sample identification and password protected levels.

Statistical Quality Control software allows analysis of results in accordance with ASTM D6299.
