Choosing a Digital Pressure Gauge

Digital pressure gauges provide a direct numerical reading for monitoring, recording and comparison work. Select the instrument around the measurement requirement rather than assuming every digital display offers the same performance.

The 63 mm GNW260 range and 100 mm GNW200 range have ±0.4% FS accuracy. Because this specification relates to the full measuring span, compare the resulting allowance at the pressures you intend to read.

The GNW210 digital reference range offers ±0.05% FS accuracy for more demanding comparison work. Measurement range, calibration and the uncertainty of the complete test arrangement must still suit the procedure.

Available pressure references vary by model. Choose gauge pressure, vacuum, compound or absolute measurement as required, then check the range, connection, power supply and operating limits. Browse all pressure gauges to compare mechanical alternatives.

Accuracy, Resolution and Range

Resolution is the smallest change the display can show; accuracy describes the permitted measurement error. A display with more digits is not automatically more accurate.

Where accuracy is expressed as a percentage of full scale, the allowance is based on the complete measuring span. Calculate what that means in pressure units for the chosen model and the readings you need to take.

For reference work, consider calibration, temperature effects and the uncertainty of the complete test arrangement as well as the gauge specification.

GNW260

A compact 63 mm, five-digit digital gauge with ±0.4% FS accuracy for local pressure readings.

GNW200

A 100 mm digital range with ±0.4% FS accuracy and gauge, vacuum, compound and absolute options.

GNW210

A ±0.05% FS digital reference gauge for more demanding pressure comparison and verification work.

Frequently asked questions

Practical answers to help with selection and replacement.

Are digital gauges always more accurate?

No. Compare each model's stated accuracy. The numerical display mainly changes how the reading is presented.

Which models offer ±0.4% FS accuracy?

The GNW260 and GNW200 ranges are specified at ±0.4% FS.

Which range is intended for reference work?

The GNW210 offers ±0.05% FS accuracy. Select its range and calibration to suit the required test uncertainty.

Is calibration included?

Provision varies by product. Check the individual page and agree any required test points before ordering.
