Additel 129 - Differential Pressure Manifold

• Accurate differential pressure calibration at high line pressure
• Fine pressure adjustment for superior measurement precision (±0.002% FS)
• Quick-connect fittings for fast and tool-free operation
• Compatible with a wide range of pressure calibration tools including pumps, deadweight testers, and piston gauges
• Rugged, field-ready design for enhanced durability and reliability

The Additel 129 Differential Pressure Manifold is an advanced calibration accessory designed to simplify and improve the accuracy of differential pressure measurements, especially under high static pressure conditions. Engineered for use with Additel pressure calibrators such as the 226 and 227 series, this manifold allows professionals in industries like oil & gas, power generation, and process control to achieve stable and repeatable results in demanding environments.

This precision manifold enables you to first build up a high line pressure, isolate one side, and then finely adjust the pressure on the other side to perform accurate differential calibrations. This innovative design ensures precise control without the need for Teflon tape or wrenches—dramatically reducing setup time and minimizing the risk of leaks or inaccuracies.

The Additel 129 manifold isn't just a piece of equipment—it’s a critical tool for improving productivity and measurement confidence. Its user-friendly configuration reduces calibration time and enhances operational efficiency in both laboratory and field settings.
