Particle Analyser

The Ultimate Portable Service Tool

Since the hydraulic power industry was finally recognised in 1925 there has been a growing concern over the contamination and cleanliness of hydraulic fluid power systems.

The experience of both the designers and users of hydraulic systems highlights that 75% of system failures are a direct result of particulate contamination with up to 90% of these failures due to abrasive wear.

The basis of contamination control is knowing the cleanliness level of the fluid, therefore contamination testing of hydraulic fluids is fundamental when cleaning oil systems such as hydraulics, transmissions, turbines, compressors and other fluid power systems.

Quality Control

HTL pride themselves on their unrivalled levels of customer service including after sales support and the range of HTL products and services readily available to customers, therefore to help you meet system and quality control requirements, HTL offer a Laser Particle Analyser.

Available Now

Available for both hire and purchase and supplied with a simple ‘know how’ step by step guide makes the HTL Laser Particle Analyser is the ultimate portable service tool.

For users of hydraulic, lubrication and transmission systems, the HTL Laser Particle Analyser is highly accurate. The system counts and sizes particles of solid contaminants in fluid power systems, on-line to 400 bar and with a typical test time from 1 minute. It operates with a single action constant low pressure pumping unit to ensure that a steady flow is achieved for every test ensuring that this is a quick process which will help to reduce down time and incurred costs caused by contamination.

With a lightweight yet durable case, the HTL Laser Particle Analyser is the essential contamination sensing technology for use on-site providing quick results and preventing future incalculable costs.
