Key Features

ISO
CompliantFully compliant with ISO 4406:1987/1999 at 4 µm(c), 6 µm(c) and 14 µm(c) based on ISO 11171, providing both standard method and refined methodology

Flexible
SamplingFlexible Sampling: Pressureless sampling as well as pressurised sampling up to 420 bar (6000 psi), with a range of flexible options including the Liquids Auto Sampler

Multilingual AccessibilityMultilingual Accessibility: Display and print-out formats in English, Spanish, Dutch, Finnish, Portuguese, Russian, Chinese and French. The system can be programmed to any other language as an option

Touch
ScreenTouch Screen: User-friendly touch screen operation with a graphic display gives an easy view of various information. Straightforward operation, and display colours can be changed

Printer
OptionPrinter Option: An optional printer allows results to be printed directly from the instrument for immediate hard-copy reporting

Rugged
CaseRugged Case: An optional rugged steel case with insulated foam protects the unit and is shake proof for guaranteed protection

Programmable MethodsProgrammable Methods: Operators can create and save their own test methods. Any method saved to memory can be recalled and run directly from the instrument

Straightforward OperationStraightforward Operation: An intuitive menu structure ensures seamless user navigation, including a convenient and easy-to-follow navigator for calibration

Temperature DisplayTemperature Display: An LCD temperature display shows sample temperature directly on the instrument to support measurement accuracy

High
PrecisionHigh Precision: The volumetric cell design of the sensors guarantees the highest accuracy, resolution and statistical information. Measurement time can be set to the application’s needs, and a pressurised sensor avoids the formation of gas bubbles

PAMAS S40 / Portable particle counting
Count and size particles.
Wherever testing happens.

Designed for oil and hydraulic fluids
The PAMAS S40 portable oil particle counter is fully compliant with ISO 4406, including ISO 11171, providing both standard method and refined methodology. The PAMAS S40 is a portable particle counter system designed to count and size particles in oil and hydraulic fluids.
Guided operation
Simple controls.
Instant measurement results.
A guided menu, a backup keypad, and results on paper before you leave the bench.
The system contains a backlit touch screen for easy access to the guided menu. It also contains an additional membrane keypad for easy operation of the oil particle counter. The integrated printer provides instant hard copies of measurement results.
Designed for easy operation.
Fully compliant with ISO 4406 at 4, 6, and 14 µm(c), based on ISO 11171, for standard and refined cleanliness reporting.

Precision + Range
Every particle.
Every pressure.
A wear-resistant ceramic piston pump holds a constant flow across pressureless, low-pressure, and high-pressure sampling up to 420 bar (6000 psi). The PAMAS HCB-LD-50/50 volumetric sensor is calibrated to 4–70 µm(c) per ISO 11171 as standard, with an optional 2–100 µm calibration per ISO 4402, at a maximum particle concentration of 24,000 P/mL.
Built for field and bench.
Standard sampling covers fluids up to 200 cSt, extending to 350 cSt under pressurized sampling and 1,000 cSt on the lube oil system.
