Diving Pressure Gauges
and Flowmeters

The 3D Instruments 2564 Series Precision Caisson Gauge is used inside the chamber and reads ambient chamber pressure.

The 3D Instruments 2554 Series Precision Test and Depth, Pressure Gauges feature the "Direct Drive Difference" and are the ideal choice for your demanding pressure monitoring or test and calibration applications.

The advantage of Perma-Cal direct drive over conventional C-tube gauges is simple; there is only one moving part. No gears, linkages or springs to wear or break.

WIKA Pressure Gauges are commonly used on compressors, pumps, pneumatic and hydraulic systems and a variety of other heavy duty applications in industrial environments.

WIKA Liquid Filled Pressure Gauges are commonly used on heavy-duty service in industrial environments.

The Dwyer Differential Pressure Gauges boasts Magnehelic gauge movement that quickly indicates low air or non-corrosive gas pressures — either positive, negative (vacuum) or differential.

The WIKA Pressure Gauges are commonly used on compressors, pumps, pneumatic and hydraulic systems and a variety of other heavy duty applications in industrial environments.

Duplex Hand Operated Pressure Calibration Pump with Vernier provides a stable pressure calibration source.

The 3D Instruments Model 8112-3000 Duplex Handpump is a portable, hand-operated device that utilizes a hydraulic fluid to generate up to 3000 psi (200 bar) of positive pressure via hand pump action.
