Dead Weight Testers

Dead weight testers have been used for many years and are the accepted industry standard for providing high accuracy pressure calibration. At GNW, we supply DWT's from Wika / DH Budenberg, and Ametek so we can offer the very best instrument to suit your application and budget.

Dead Weight Testers are ideal in use of calibrating, setting, testing, and repairing pressure measurement and control devices. Pneumatic and hydraulic versions are available. Pneumatic testers are ideal for oxygen use and breathing air equipment. Our devices are traceable to National Standards assuring instrument accuracy.  We can also offer UKAS certificates if you require.

Field portable models can be provided. A single carrying case holds the pressure generation pump as well as the necessary tools and accessories. A second box contains the weights used for pressure generation.

We can refurbish and offer a traceable calibration service for hydraulic or pneumatic dead weight testers from all manufacturers.

GNW have a range of finance options available to let your spread the cost of your purchase over a number of years. Please contact us for a quotation.
