The Qumensus Optical Laser Particle Counter is an advanced contamination analysis instrument designed to provide precise and reliable monitoring of particle size distribution and quantity in lubricating and hydraulic oils. Built on the proven principle of laser light blockage, this device delivers highly accurate results with excellent repeatability, making it an essential tool for industries where lubricant cleanliness directly impacts equipment reliability and operational safety.

Utilizes a semiconductor laser and a precision syringe-based sampling system to ensure accurate sample volume control and rapid analysis.

In addition to particle counting, the instrument offers water content measurement (RH% or ppm) and turbidity analysis (ASTM D4176), enabling comprehensive oil condition assessment.

Positive/negative pressure regulators eliminate air bubbles and allow analysis of highly viscous oils up to 320 cSt at 40℃.

Equipped with a full-color touchscreen LCD for intuitive operation, with adjustable sampling volume, speed, and cleaning modes.

Integrated contamination codes such as ISO 4406, NAS 1638, SAE AS4059, ensuring compliance with global maintenance requirements.

Measurement results can be stored, retrieved, and printed immediately or transferred via RS232 to external systems for archiving and trend analysis.

Supports calibration with ISOMTD and ACFTD standard materials, offering flexibility for different applications.

By detecting harmful particles and water contamination before they reach critical levels, operators can avoid costly breakdowns and unplanned downtime.

Comprehensive contamination monitoring strengthens predictive and condition-based maintenance programs.

Reduces oil replacement frequency, lowers spare part consumption, and extends equipment lifespan.

Suitable for diverse sectors including power generation, aviation, petrochemicals, iron & steel, cement, marine, transportation, automotive, and heavy machinery. Compatible with hydraulic oil, lubricating oil, engine oil, turbine oil, gear oil, aviation oil, and more.

1. Collect the oil sample in the provided bottle and insert it into the sampling chamber.
2. Set parameters on the touchscreen (sample volume, flow rate, particle size channels).
3. Activate the bubble removal function if needed for viscous oils.
4. Start the measurement; results will be displayed in real time.
5. Print results instantly or export to PC for further analysis and record keeping.
6. The Qumensus Laser Particle Counter is not only a precision measuring instrument but also a comprehensive oil health monitoring solution. By integrating particle counting, moisture detection, and turbidity analysis into one platform, it offers unparalleled value for operators seeking to maintain optimal lubricant quality and maximize equipment performance.
