AvCount Lite Particle Counter, SA1800-2

The AvCount Lite portable automatic particle counter provides reliable results for determining the size and distribution of particles in light and middle distillate fuels, including aviation fuel and kerosene, biodiesel, low viscosity oils, and hydraulic oils.

The particle counters simple operation makes testing bottle samples or on-line quick and easy, with results in under 3 minutes.

The AvCount Lite displays the cumulative, particles/ml and ISO 4406 cleanliness codes. Up to 600 results can be saved to the internal memory, downloaded to a PC/laptop or printed via the internal printer.

Methods:  ASTM D975, ASTM D7619, IP 565, DEF STAN 91-091, DEF STAN 91-86, ISO 4406

Sample viscosity:
The AvCount Lite can analyze samples with kinematic viscosities of up to 64 mm2/s. When used in conjunction with the optional Sample Delivery System, the viscosity range is extended up to 200 mm/s.

Precision and accuracy:
AvCount Lite is fitted with a precision dual piston pump. When measuring samples from a bottle, the pump draws an aliquot of a sample through the measurement cell at a consistent flow rate. When connected to a pressurized line, the pump provides accurate metering and control.

Calibration and verification:
AvCount Lite utilizes 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 authorized regional laboratories.
