Test Gauges
Used to check calibration of other gauges or where extremely accurate measurement is required. GNW's test gauges offer an accuracy better than 0.25% or 0.5% of full scale at any point.
All test gauges are manufactured to a very high standard and are all issued with a traceable calibration certificate. Test gauges are available in a selection of cases (100,150,200 & 250mm) manufactured to a pressure range of your choice from -1 to +1000 bar. Test gauges are also manufactured with a fitting size of your choice and also have the option of being fitted with mirrored dials. All test gauges are fitted with knife edge pointers as standard. |
Please note - When used for checking calibration accuracy of other gauges, a "Master Test Gauge" must be at least 4x greater accuracy than the instrument being checked. For example, with a 0-400 bar range the instrument would have an accuracy of better than ± 1 bar and could be used to check and certify any other gauge where the accuracy should be ± 4 bar or higher.
We can also supply digital master test gauges with a very high accuracy of 0.025% full scale with ranges from -1 to 700 bar. Please see our digital gauge section for more details.
