PAMAS<\/a> has played a central role in launching the world\u2019s first commercially available ISO 11171:2022-<\/a>calibrated particle counter certified for operation in explosive atmospheres.<\/strong><\/p>\n

\u00a0<\/p>\n

In partnership with The ATEX Particle Counting Company (APCC), <\/a>formerly Reynolds Contamination Control, we are proud that the new\u00a0S50-P-Z1<\/a>\u00a0and\u00a0OLS50-P-Z1\u00a0systems are already attracting significant global interest.
At the core of these innovations are\u00a0PAMAS ISO 11171<\/a>-calibrated sensors, the only calibrated particle-counting technology on the market suitable for\u00a0oils, fuels, saltwater, and water-based fluids\u00a0while fully compliant with\u00a0ATEX, IECEx and UKEX\u00a0requirements. This capability gives APCC<\/a> access to previously unreachable sectors including\u00a0oil & gas, shipbuilding, green energy, chemical and pharmaceutical industries, food processing, mining, and traditional energy generation.<\/p>\n

A Step Change for Hazardous Locations
<\/strong>Historically, particle counting in\u00a0Zone 1 explosive atmospheres\u2014such as offshore platforms, airport refuelling zones and petrochemical facilities\u2014required samples to be manually collected and transported off-site to laboratories due to the risks of using electrical devices in these environments. Through APCC\u2019s<\/a> collaboration with Italian Exd specialists\u00a0MAM, and the engineering work led by APCC<\/a> Engineering Director\u00a0Peter Remmert, this barrier has now been removed. Together, we have developed an explosion-proof\u00a0aluminium or AISI 316L\u00a0enclosure that safely houses the advanced\u00a0S50-P-Z1<\/a>\u00a0and\u00a0OLS50-P-Z1\u00a0particle counters, enabling\u00a0live on-site data\u00a0and full\u00a0cloud connectivity.<\/p>\n

System Overview
<\/strong>The\u00a0S50-P-Z1<\/a>\u00a0and\u00a0OLS50-P-Z1\u00a0are fully automatic Exd optical particle-counting systems using a laser-diode light source for continuous cleanliness monitoring. They report contamination in accordance with\u00a0ISO 4406:2021<\/a>,\u00a0SAE AS 4059G, and provide particle counts across\u00a0eight size channels.<\/p>\n
