IOS1210EUR - Robust oil sampler particle counter

Accurate condition monitoring made quick, simple and cost effective.
The icountOS (IOS) is an innovative solution to the challenge of measuring the quality of hydraulic oils and hydrocarbon fuels in many different applications: from renewable energy, marine and offshore, to manufacturing, mobile, agriculture, military and aerospace.
Compact, lightweight and robust, the truly portable IOS makes field analysis simple, quick and easy.
Able to sample directly from a hydraulic reservoir, barrel, vehicle fuel tank or from a high pressure online hydraulic system with the addition of a pressure reducing adaptor; the IOS is undoubtedly the most adaptable contamination service tool available today.

The system is completely self contained, with a laser detection particle counter, battery and pump plus memory with web page generator for data download onto any PC or laptop - combined into a single unit.

The IOS uses Parker’s proven laser detection technology, which delivers precise, repeatable, reproduceable results in real-time detection of both particulates, down to 4 microns (c) and dissolved water. Just as importantly , the IOS has been developed to offer a wealth of features, combined with simplicity and ease of use, at a cost that is far lower than competing systems, and which fits within most maintenance budgets.


- Easy to set up and use this CE compliant instrument
- Selectable 12 language instruction manual menu
- Calibration to ISO procedures
- Compact and robust, lightweight design.
- Precise, repeatable and reproduceable results in real-time detection
- Waterproof case
