The GNW2000 4-Way Pressure Calibration Manifold is designed to simplify pressure calibration by providing multiple connection points from a single pressure source. The manifold allows up to four pressure instruments or sensors to be connected simultaneously, making it ideal for calibration laboratories, workshops and field service work.

Each port is fitted with an independent isolation valve, allowing instruments to be connected, isolated or removed without disturbing the remaining devices. This enables efficient multi-point calibration and comparison testing when working with pressure gauges, transmitters or digital reference instruments.

The manifold connects directly to a pressure generation source such as a comparator pump or pressure controller via a pressure hose. Its compact and lightweight design makes it well suited for both bench calibration and portable field use.

The GNW2000 is constructed from a combination of aluminium alloy and stainless steel, providing excellent corrosion resistance and strength while maintaining low weight.

Two versions are available:

• Pneumatic version: -1 to 250 bar
