Frequently asked questions (FAQ)

Which range should I choose? Choose a range that exceeds your highest expected pressure peak. For general hydraulics, 400 or 600 bar is often suitable.

Is 0.1% accuracy necessary? Only if you have requirements for high precision, calibration or documentation with narrow tolerances. Otherwise 0.25–0.5% is more than enough.

Can I log without software? Yes. With the data logger, data is saved as CSV and transferred via USB – no special software required.

Can it withstand harsh environments? Yes. The metal housing provides high ruggedness and a long service life in both service and production.
