Forberg Scientific Inc. named as Wika Authorized Pressure Gauge Calibration / Diaphragm Seal Filling Center.

Forberg Scientific has been certified by Wika Instruments as a factory-authorized provider of NIST traceable calibration services for pressure gauges and pressure transmitters. Forberg has also been certified as a factory-trained center to provide diaphragm seal filling services for all types of Wika diaphragm seal and pressure instrument combinations.

Forberg has invested in a state-of-the-art Wika designed fill-bench that allows us to fill both standard and mini diaphragm seals with a variety of fill fluids including glycerin, silicone, and halocarbon. Seals incorporating capillaries of various lengths can also be filled and tested by Forberg. All Forberg assembled diaphragm seals are 100% functionally tested prior to shipping to insure the highest possible quality standards.
