AvCount Lube Particle Counter – SA1900-0

The AvCount Lube particle counter determines particle concentration in oils with a viscosity of up to 200 mm2/s. FFKM seals have been fitted to resist aggressive oils.

• Simple operation
• Ideal for handling lubricating and hydraulic oils
• 3-minute test time
• Programmable via PC

With a simple test procedure and user-friendly features, operator skill or expertise is kept to a minimum.

AvCount Lube can hold up to 3 test methods with custom methods created on a PC before being uploaded using the supplied ProTrend control and analysis software.

Test progress and results for up to 6 size bands are displayed as cumulative particles/ml and ISO 4406, NAS 1638, and AS4059 cleanliness codes.

Supplied with: sample probe, waste pipe, universal voltage power supplies, USB cable, calibration certificate, and USB memory stick containing handbooks and ProTrend software for test method programming and data download.

Integral Compressor
AvCount Lube comprises a light extinction automatic particle counter and a sample delivery unit. Designed to handle samples with a viscosity up to 200 mm2/s, the AvCount Lube has an integral compressor that pressurizes the sample chamber to 3 bar.

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. Seta authorized training is required to perform a calibration. Verification can be performed using AvCount Verification Material.

ProTrend (SA1810-0) is supplied with the instrument and can report results to ISO 4406, NAS 1638, and SAE AS4059 (tables 1 and 2) cleanliness codes. Using the software, you can program other test methods and cleanliness codes with up to 16 size bands.
