MP Filtri Particle Counters

MP Filtri particle counters and contamination monitors measure and display particulate contamination, moisture and temperature levels in hydraulic fluids, supporting predictive maintenance and reducing unplanned downtime across hydraulic, lubrication and subsea applications.

Particle Counter and Contamination Monitor Models

LPA3: The current portable particle counter, replacing the standard LPA2. Uses optical and photodiode technology, with a fully programmable 10.1 inch full colour touchscreen display, online real-time monitoring and live trend analysis. Compatible with the full range of MP Filtri bottle samplers for laboratory-based particle counting.
LPA2 Aviation Edition: Built specifically for the aviation industry and approved by Airbus, this variant of the LPA2 remains current for MRO (maintenance, repair and overhaul) applications, measuring and displaying results to ISO 4406, NAS 1638 and SAE AS 4059 (revision E, tables 1 and 2) standard formats. The standard, non-aviation LPA2 has been discontinued and replaced by the LPA3.
CML3: A compact, portable contamination monitor using LED light obscuration technology with 8-channel measurement, weighing 8.5 kg, with a 7 inch touchscreen display and a full day’s operation on a single battery charge. Connects to MP Filtri’s CMP View software for trend monitoring and oil analysis. Suited to mobile, construction and plant hire applications.
CML4: A more advanced compact portable contamination monitor with an integrated metering pump, allowing analysis of both pressurised and unpressurised systems. Features a 7 inch touchscreen, USB connectivity, and a data logger storing up to 4,000 results. Measures against ISO 4406, NAS 1638, AS 4059 (tables 1 and 2), ISO 11218 and GBT standards, with a capacitive RH sensor for water content measurement.

Typical Applications

Hydraulic system health checks and predictive maintenance
Laboratory-based particle counting via bottle samplers
Mobile, construction and plant hire contamination checks
Aviation MRO applications (LPA2 Aviation Edition)
Subsea and lubrication fluid analysis
Quality control in manufacturing applications

The CML3 is a compact, more affordable portable contamination monitor using 8-channel LED light obscuration technology, suited to mobile, construction and plant hire sectors. The CML4 adds an integrated metering pump for testing both pressurised and unpressurised systems, along with a data logger storing up to 4,000 results and compatibility with a wider range of international standards.
