Construction equipment hydraulic oil monitoring
We measure contamination and water in excavator and loader hydraulics on site. You do not ship a sample and wait for the result to see the oil's condition.

What we measure
In the oil, viscosity, water and moisture, oil ageing, particle contamination (ISO 4406 code) and the wear-metal trend are measured. On the machine, vibration level and temperature are monitored. When a reading moves away from the machine's normal range, the screen changes from green to amber or red. Warning signs and what they mean
What we do not measure: metal identification (which metal a particle is), acid and base number (TAN/TBN) and vibration spectrum analysis (FFT). These tests need a laboratory and a specialist. DataMonitor does not replace them. It works alongside them. The system watches for warning signs and gives early warning. It does not diagnose faults.
Construction & mobile equipment FAQ
When should excavator hydraulic oil be changed?
No single hour count fits every machine. The decision should combine the manufacturer's recommendation with the measured condition of the oil. Outdoors, dust and moisture will always get in. That makes the ISO 4406 code, the water and the viscosity trend important to track. Oil change intervals should follow test results, not the calendar (US USBR FIST 2-4).
Can oil be tested on site without sending samples away?
Yes. A sensor fitted to the machine measures the oil on site and shows the result immediately. There is no sample to ship and no wait. You can also measure a sample with the portable analyzer in the field. The lab remains available for in-depth tests such as metal type.
How can I tell if dust has got into hydraulic oil?
Dust in the oil raises the particle count and the ISO 4406 code. A particle counter shows this straight away. Dust usually gets in through worn seals, a failing filter or open entry points. Checking the filter and entry points when the code rises reduces the risk of dirty-oil breakdowns.
