The Weksler WDG4251L offers 0.5% of span accuracy, while the stainless steel sensor and socket make this product suitable not only for dry air applications but for other media as well.


This product offers selectable units of measure so rather than purchasing one gauge for each unit of measure required, the solution is one gauge for multiple units of measure.


The WDG4251L is standard with many features not offered, or offered only as options, on competitor’s digital gauge products, such as peak hold and 5 digit display. When compared to mechanical gauges the WDG4251L offers overall enhanced value
