Wide Spaced Graduations Give Excellent Readability
Because the pointer covers full scale in two revolutions, Series 1500 scales are approximately 45" long. This is more than twice as long as single-revolution gauges with the same dial diameter (8½") and longer than gauges with twice the dial diameter. The expanded scale allows a minimum of 0.045" of white space between graduations. This and a knife-edge pointer allow readings to 0.02% of full scale.

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 are supplied traceable to NIST.

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

Rugged Design
The case is heavy cast aluminum with a tempered-glass window. A heavy aluminum dial plate, with only a 1/16" opening for the pointer, isolates the capsule. Overpressuring the instrument up to 10% above its full-scale range will not damage the mechanism nor affect accuracy. A built-in relief valve has a dumping capacity, which protects the case from applied pressures over the maximum case pressure rating.
