GNW210 digital reference pressure gauges

The GNW210 is the reference option within the GNW digital gauge range. Use it with suitable pressure-generation equipment and a controlled procedure when comparing instruments.

Plan the range, calibration and measurement uncertainty together. The gauge accuracy is one part of the test arrangement; it does not by itself establish the uncertainty of a calibration.

Compare the digital gauge range, or contact GNW to discuss the measurement.

Planning reference measurements

Choose a range that covers the test points without making the instrument unnecessarily large in span. Review the calibration results and the uncertainty required by your procedure.

Use a stable pressure source and suitable connections, and follow the test method for settling time and readings.

Reference performance

±0.05% FS accuracy for demanding comparison work.

Range selection

Choose a span suited to the pressures you need to measure.

Calibration planning

Check certificate provision and any required test points before ordering.

Applications

Digital Reference Gauges can support the following tasks when selected for the duty.

Gauge comparison

Compare another pressure indicator against a suitable reference.

Transmitter checks

Use a reference pressure reading as part of a transmitter test arrangement.

Test benches

Build the instrument into a controlled pressure-verification procedure.

How to choose

choose the pressure type; check range and performance; confirm the connection; plan the installation.

Choose the pressure type

Match the measurement reference to the job and select an available model.

Check range and performance

Assess the required uncertainty across all test points.

Confirm the connection

Check the thread, wetted materials and pressure-medium compatibility.

Plan the installation

Review power, environmental limits and calibration requirements.

Frequently asked questions

Practical answers to help with selection and replacement.

What accuracy does the GNW210 offer?

The GNW210 is specified at ±0.05% FS. This is a percentage of full scale, not a percentage of the displayed reading.

Can I use this gauge to calibrate another instrument?

It can serve as a reference where its range, calibration and uncertainty suit the procedure. Assess the complete test arrangement.

Which range should I choose?

Cover the required test pressures and assess performance at the lowest as well as the highest test point.

What calibration documentation is available?

Check the product page and contact GNW to agree any specific test points or documentation before ordering.
