Overview
Condition-based oil changes, decided in the field
Fully automatic sampling to measure contamination level and particle count of in-use oil, with automatic storage and a 7" touch screen.
What it measures
What it measures
Particles
1–100 µm / 4–70 µm (c)
Semiconductor laser with 1 µm sensitivity (ISO 4402).
Built-in standards
ISO 4406 · NAS 1638 · GJB420A/B
Also GB/T 14039, with ±0.5 level accuracy.
Sampling
automatic, 50–300 mL/min
Constant flow and controlled volume, online up to 10 MPa.
How it works
Measurement principle
Automatic sampling with a laser optical particle-counting sensor for ISO cleanliness level.
1
Precision samplingThe system doses the sample with controlled flow and volume.
2
Laser in the flowThe semiconductor laser lights the oil as it passes.
3
Channel countingEach particle is counted and sized by range.
4
Contamination gradeThe result comes out by the chosen standard, ready to decide the change.
How to use
From the case to the result, no fuss
1
Position and power onSet it on a level surface and switch the instrument on.
2
Configure before measuringSet the sample number and the detection standard; adjust the flow rate.
3
Start the testSampling is automatic; the result is the average of the detections.
4
Read and compareContamination grade and counts in real time on the 7-inch screen.
5
Save and exportData saved with automatic trending and USB export.
6
Clean the sensorAfter use, clean with the indicated agent; never run the sensor dry.

Common questions
FAQ
Does it measure continuously?
Yes. In online mode detection does not stop and keeps acquiring data, besides the set-number-of-detections mode.
Which standards does it deliver?
ISO 4406, NAS 1638, GJB420A/B and GB/T 14039, built into the instrument.
How do I decide the oil change?
By tracking the contamination grade and its trend: the change becomes based on the oil's real quality, extending the lubricant's life.
