Direct Readout, No Barometric Adjustments
Because applied pressure is referenced against an evacuated element, WIKA gauges read out true absolute pressure directly. No corrections or adjustments required.

Wide Spaced Graduations Give Excellent Readability
Because the pointer covers full scale in two revolutions, Series 1500 scales are approximately 45" long. This is 2½ times as long as single-revolution gauges with the same dial diameter (8½") and even 20% longer than gauges with twice the dial diameter. The expanded scale allows a minimum of 0.045" of white space between graduations.

Calibration is Traceable to National Institute of Standards and Technology (NIST)
A computer-assisted plotter marks calibration points and the graduations between them on each dial. This produces a scale which precisely matches the characteristics of its own mechanism and pressure element. Instruments supplied are certified traceable to NIST.

Performs Better than the Rated Accuracy
Excellent readability, custom dial calibration, and individual assembly and adjustment of each mechanism add up to an accuracy of 0.066% full scale. This figure is the minimum performance, which can be expected. After rigorous testing, any WIKA gauge which fails to perform better than the rated accuracy is rejected.

Rugged Design
The case is heavy cast aluminum.

The case is heavy cast aluminum.

Ranges of 100 psia and above have extra strong tempered glass windows and a blowout plug in the back of the case. Overpressuring these gauges up to 10% above full scale will not damage the mechanism nor affect accuracy.
