WIKA High Precision Pressure Gauge Series 300-6G

Convenience in the Low Pressure Ranges
Available in the low-pressure ranges (down to 0 to 10" water), the Series 300 is a reliable mechanical indicator which reads out gauge pressure directly.

Excellent Readability
With a 16" scale, the Series 300 offers excellent readability. (In the lowest range, 0 to 10" water, the minimum graduation represents 0.05" water.) Graduations have ample white space between them. This and a knife-edge pointer read-out is better than 0.1% of full scale. Numbers on the dial are horizontally placed and a mirror ring eliminates parallax errors.

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 matches precisely the characteristics of its own pressure capsule and mechanism. Instruments supplied are certified traceable to NIST.

Performs Better than the Rated Accuracy Of 0.3% of Full Scale
A readable scale, individually matched dials and mechanisms, excellent repeatability, and a precision mechanism add up to an accuracy of 0.3% full scale. These figures are the minimum performance which can be expected. After rigorous testing, any WIKA Series 300 gauge which fails to better the rated accuracy is rejected.

Sensitive, Rugged, and Overpressure Protected
A small, sensitive capsule responds to minute pressure changes. Low-inertia parts throughout and a linkage containing flexures and jewel bearings mean high sensitivity. The case is heavy cast aluminum with a high tempered glass window. A blow-out plug in the back of the case is designed to relieve at the slightest pressure build-up. Overpressuring the instrument up to 10% above its full scale range will not damage the mechanism nor affect accuracy.
