Fast, Accurate Contamination Analysis for Oils and Fluids, On-Site or On-Line.

The YJS-150 is a portable particle counter based on the light-extinction (light-blockage) principle, used to measure the size and quantity of solid particles in liquid. It's widely used across aviation, aerospace, electric power, oil, chemical, transportation, port, metallurgy, machinery and automobile manufacturing to detect solid-particle contamination in hydraulic oil, lubricating oil, transformer oil (insulating oil), turbine oil, gear oil, engine oil, jet fuel and water-based hydraulic oil, as well as insoluble particles in organic liquids and polymer solutions.

Key Features

1.  Light-Blockage Detection — As particles pass through a narrow detection zone, they block light traveling perpendicular to the flow, changing the sensor's output signal in direct proportion to each particle's cross-sectional area.

2.  Lab, Field, or On-Line Use — Works as a standalone instrument in the lab or in the field, or can be installed directly on hydraulic drives, lubrication systems, oil filter systems, washing systems, and test benches for continuous on-line cleanliness monitoring, with optional interface components to match your setup.

3.  Built for Unattended, Continuous Monitoring — RS232 and analog signal outputs satisfy DCS and site-instrument requirements, so unattended systems and running machinery can be tracked continuously with real-time alerts and wear-trend diagnostics.

4.  Flexible Off-Line Sampling — Pairs with an off-line sampling chamber to test oils of different viscosities, closing the gap that fixed lab desktop instruments can't cover, while supporting both standard and custom detection evaluations.

5.  High Precision and Repeatability — The light-blockage sensor delivers quick detection, strong anti-interference performance, and high resolution power for consistent, repeatable results.

6.  Accurate Sampling System — A precision sampling mechanism maintains constant sampling velocity and tightly controlled sampling volume for reliable readings.

7.  Simple, Direct Operation — A color LCD run by an integrated industrial control computer with touchscreen operation shows results directly, and a built-in printer can output detection reports on the spot.

8.  Multiple Built-In Pollution Standards — Supports GB/T14039, ISO4406, NAS1638, GJB420A, GJB420B, SAE749D, GOST 17216, AS4059D and other international particle pollution degree standards, with custom standards also supported.

9.  Stored Calibration Curves — ACFTD, ISOMTD and ROST calibration curves are available to minimize conversion error and guarantee measurement precision; self-calibration is supported using standard samples and a guided operation video.

10.  Flexible Data Transmission — RS232 or RS485 connectivity lets you transfer, store and manage detection data directly from a connected computer.

11.  Compact and Rugged — Small, lightweight, and built for both laboratory and field work, with a solid, durable shell rated for anti-interference and high-temperature performance.
