JPL-7 Ferrous debris monitor measures the content of wear shavings by using the principle of electromagnetic induction and the changes in the magnetic field of the sensor coil caused by ferromagnetic wear shavings in the oil sample. It has a good linear relationship with the iron shavings content and particle size of the oil sample.

It features high sensitivity, accuracy and repeatability. No sample pretreatment or organic solvents are required. It can measure the PQ index of ferromagnetic metal abrasive particles in various oil samples within a few seconds. The PQ index is a dimensionless quantitative figure. It is widely applied in fields such as national defense, aerospace, shipping, power, petrochemical, metallurgy, mining, and road transportation.

1. The total amount of large-sized ferromagnetic particles in the equipment oil is quantitatively determined. One data is measured every 5 seconds, which is fast and has good repeatability

2. It has high sensitivity and a resolution of up to 1PQ

3. No sample pretreatment is required and no organic solvents are needed

4. Fast detection speed

5. The iron filings content in lubricating oil and grease samples can be analyzed

6. It simultaneously meets the usage requirements of both industrial sites and oil monitoring laboratories

7. The operation of the instrument is extremely simple and can be mastered within a few minutes without the need for professional training

8. The WINDOWS system is equipped with functions such as data logging, querying, correction and trend analysis

9. Monitor the misoperation function. If there is an operation error, a prompt will be displayed on the screen
