AvCount Lite Particle Counter

Part Number SA1800-0

The AvCount Lite particle counter provides reliable results for determining the particle concentration in liquid fuels and oils, including aviation fuel cleanliness to Defence Standard 91-091.

• Simple operation
• Portable, compact instrument
• Under 4 minute test time
• Programmable via PC

The portable particle counter features a simple test procedure and user friendly features, operator skill or expertise is kept to a minimum.

AvCount Lite can hold up to 3 test methods with custom methods created on a PC before being uploaded.

Test progress and results for up to 6 size bands are displayed as cumulative particles/ml and ISO 4406 cleanliness codes.

Skydrol resistant version available


Precision & Accuracy AvCount Lite is fitted with a precision dual piston pump. When measuring samples from a bottle, the pump draws an aliqot of sample through the measurement cell at a consistent flow rate. When connected to a pressurised line, the pump provides accurate metering and control. A pressure reduction system is available for applications above 10 bar.

Calibration & Verification AvCount Lite utilises 16 point calibration. Calibration can be carried out either using NIST traceable standard solutions or by interfacing with a primary calibrated ‘Master’ AvCount Lite. Calibration can be carried out at a user site or at our authorised regional laboratories
