The manufacturing of these precision pressure gauges and calibrators has been relocated from Germany and are now being made in the U.S. by WIKA Instrument Corporation. They are certified to NIST Standards before shipment. The Certificate of Calibration is included at no additional cost

Series 1000 6" Dial High Precision Differential Pressure Gauges

Series 1000 Gauges have capsule-type pressure elements and pressure and static connections. High differential pressure is applied to the capsule; low pressure, to the case. Available in 22 standard ranges, they combine aneroid convenience with liquid-column accuracy. They are compact for efficient panels and consoles, yet readability is excellent.


Size: 6" dial

Scale Length: Approx. 30" through 2 pointer revolutions

Range: To 150 psi

Accuracy: 0.1% of full scale

Repeatability: 0.03% of full scale

Sensitivity: 0.01% of full scale

Hysteresis: 0.1% of full scale for all ranges except 150 psi or equivalent, which is 0.2% of full scale

Maximum temperature effect: 0.1% of full scale per 10C/50F change from 23C/ 73.4F

Pressure element volume: 6.9 cc with pointer at zero; 8.6 cc at full scale. For the range 0-125” water only: 6.3 cc with pointer at zero; 8.0 cc at full scale

Case volume: 1775 cc, with overpressure relief valve built into the back of the case

Maximum case pressure: 35 psig

Maximum case leak rate: Will not exceed 6.34 x 10-5 std cc/sec 0.0018 psi/hr.

Case connections: 1/8" female NPT pressure and static connections. Stainless steel filters are mounted in the orifice of both units and are located in the bottom of the case.

Case construction: Cast aluminum with tempered-glass dial cover. The bezel has no screw holes; the case has special clips for easy flush mounting.
