The world’s first commercially available ATEX zone 1 IECEx classification particle counter calibrated to ISO11171:2022. & fitted with a highly accurate IOCTO NP330-F water sensor, housed in a MAM Exd enclosure. 

Fully automatic Exd optical particle counting system with LASER-diode light source for continuous presentation of cleanliness codes in ISO4406:2021 8 channels.

• Cost effective, high performance laser based online particle counting system with eight size 8 channels
• Flexible integration into PLC or Cloud solution
• LED display showing the contamination class code according to ISO 4406:2021 in the size classes > 4 μm(c), > 6 μm(c) and > 14 μm(c)
• The volumetric cell design of PAMAS sensors measures 100% of the sample flow and guarantees highest accuracy and reproducibility
• The particle number and size distribution of all 8 size channels is reported in real time to PC or PLC (programmable logic controller). The optional analysing software saves the measuring results and shows them in tables and graphs. This makes trends and events easily visible
• Due to its measuring accuracy and its trend monitoring feature, S50-P-Z1 Fuel reduces the risk of failures and ensure the reliability of the controlled operating system
• Every S50-P-Z1 particle counter is calibrated and certified individually to ISO 11171:2022
  Highly accurate IOCTO NP330F water sensor, scaled in ppm
• Classification of: II 2 GD Ex db IIC T6 Gb Ex tb IIIC T85°C Db IP66

• ATEX - INERIS 14ATEX0056X
• IECEx - IECEx INE 14.0037X
• UKCA - UKCA CML 21UKEX1865X

The ATEX Zone 1 Particle Counter is the first of its kind, designed for real-time fluid contamination monitoring in hazardous environments. It integrates advanced particle and water sensing technologies with ATEX Zone 1 and IECEx certification, enabling safe, precise, and compliant measurements in explosive-risk zones.

• ISO 11171 compliant: Calibration traceability to the international standard for particle size distribution in hydraulic fluids, ensuring globally benchmarked reliability.

 

• Pamas HCB particle sensor: High-resolution detection of solid contaminants in fluids, trusted for hydraulic, fuel, and lubrication oil monitoring.
• Iocto NP330-F water sensor: Measures dissolved water content in fluids. Custom laboratory calibration to 50 ppm provides ultra-precise detection of free and dissolved water levels.
• Pamas HX particle sensor (aluminium case version): Designed for monitoring fuel oil, diesel B7, and Jet A1 aviation fuel.

• Certified for ATEX Zone 1 and IECEx hazardous environments.
• Enables in-situ, real-time monitoring directly in explosive-risk zones, eliminating the need for external sample handling.

• Energy & Offshore: Safe condition monitoring of hydraulic and lubrication systems in oil & gas.
• Chemical Processing: In-situ monitoring without breaking containment.
• Aerospace/Defense: Ensures fluid reliability under extreme operational constraints.
• Water Security: Offshore desalination plants can now benefit from real-time particle and dissolved water measurement in ATEX environments, ensuring both process efficiency and water purity.
• Aviation: Aluminium-case version with Pamas HX sensor enables direct underwing deployment during aircraft refueling, providing contamination status at the point of fueling — a world first for aviation safety and ground operations.We provide a full range of Structural Engineering services, including design, analysis, and construction support.
