Handheld Meter for Moisture in Oil Measurement
Oilport 30 Set
The Oilport 30 handheld meter is dedicated to portable monitoring of moisture and temperature in oil.
The simple and intuitive operation via TFT touch screen and the built-in data logging function make the Oilport 30 hand-held the ideal tool for fast and reliable oil analysis.
Measurands
- Relative water content / water activity [aw]
- Absolute water content [ppm] Temperature [°C / °F]
Oilport 30 accurately measures water activity aw and temperature T. By entering oil-specific parameters, the hand-held meter calculates water content in oil (ppm).
Probes
- Pressure-tight oil probe up to 20bar Together with the ball valve assembly set, the oil probe can be fitted and removed without interrupting the oil circuit.
- Short oil probe Ideal for quickly determining the moisture in oil samples.

FAQ
Calibration for a specific oil is a laboratory procedure for determining the saturation curve of the oil. The saturation curve is described by two parameters (A and B). These parameters are used for setting up the moisture in oil sensor for correct calculation of the water content (ppm) out of the measured temperature and water activity (aw).
Sensor replacement is possible for the EE360 models with the ordering code including PC4 (pluggable probe). Please see the operation manual or detail and spare part code ordering guide.
Please see the cleaning instructions.
No, coating is not available for the E+E MIO sensors.
The standard scope of supply of E+E MIO sensors includes an inspection certificate according DIN EN 10204 - 3.1. For details on calibration certificates please see our white paper "Calibration and Traceability in Measuring Technology".
No, mineral transformer oils from different manufacturers are quite similar. A and B parameters are the same.
