Parker particle counter now included in DEFSTAN 9191

The latest Icount ACM20 particle counter from Parker Hannifin, the global leader in motion and control technologies, is now included as test equipment for the determination of dispersed contamination in jet fuel, in line with the DEFSTAN 9191 Jet Fuel Specification. The portable device is a proven solution for analysing hydrocarbon and aviation turbine fuels quickly and accurately, in accordance with the UK’s Energy Institute test method IP 564.

Following the DEFSTAN inclusion, the Icount ACM20 can now be used in place of traditional and often subjective methods of measuring contamination levels in jet fuels, such as the Clear & Bright Visual test method (IP216 or ASTM D2276) and the Gravimetric test method (IP423 or ASTM D5452). The unit is used to detect contamination invisible to the naked eye down to four microns in size, which can be self generated as a result of water contamination causing rust, or the ingress of solids through tanks vents, open storage vessels or as a result of wear of mechanical systems.

Using light obscuration technology, the new particle counter produces accurate and reliable test results in just two minutes. When used in the laboratory, the Icount ACM20 uses a case mount pump to draw a test sample into the machine. When used in the field, it can be connected directly to an existing sample point using a supplied quick connect fitting up to a maximum of 420 bar pressure. The test results are stored on an internal memory and can be viewed on the handset LCD screen and subsequently downloaded to a PC or laptop via an RS232 connection for further analysis.

The Icount ACM20 features a number of self-diagnostic fail-safe checks to ensure the integrity of sampling and final results. The memory is capable of storing 300 test results which can be used for product trend analyses, statistical records for routine maintenance procedures or proof or product cleanliness at point of transfer to name but a few applications. In addition to the unit used for IP564, Parker also offer the Icount ACM in an ATEX approved stainless steel enclosure for safe use in hazardous environments.
