Key Types of Oil Particle Counters

Suppliers in Gujarat typically offer three types of oil particle counters, all designed to report cleanliness levels according to industry standards like ISO 4406 and NAS 1638:

Portable/Field Units:
1. Use Case: Quick, on-site measurements of hydraulic or lubricating oil taken directly from machine reservoirs or sampling valves.
2. Focus: Ease of use, ruggedness, and rapid reporting for predictive maintenance teams.
Laboratory/Benchtop Units:
1. Use Case: High-accuracy, low-volume batch testing of fluid samples sent to a central lab (common in large manufacturing or testing facilities).
2. Focus: High precision (e.g., HIAC or PAMAS benchtop systems) and ability to handle various fluid viscosities and opacity levels.
Online/Inline Sensors
1. Use Case: Permanent installation on critical machinery (e.g., turbines, large gearboxes) to provide continuous, real-time data on contamination levels.
2. Focus: Immediate alarm generation and integration into a central control system.

Key Compliance Standards

When sourcing an oil particle counter, ensure the supplier confirms the instrument is capable of accurately measuring and reporting data against:

• Non-Destructive Testing: They perform tests (Bubble Point, Diffusion, Water Intrusion) that correlate directly to bacterial retention tests without destroying the filter.
• ISO 4406:99: The most common global standard for reporting oil cleanliness codes.
• SAE AS4059/NAS 1638: Older standards still used in specific industries (especially aerospace and legacy systems).
