Fluke RPM4-AD Reference Pressure Monitor

The Fluke RPM4-AD Reference Pressure Monitor, stands as a beacon of excellence in the realm of pressure calibration. Manufactured by Fluke Calibration, this instrument is designed to measure and display pressure in various units, covering altitude, airspeed, and conventional pressure units. Let’s explore the key features and capabilities that make the RPM4-AD an indispensable tool for precision measurement.

Compact and Rugged Design

One of the defining characteristics of the RPM4-AD is its compact and rugged design. This reference pressure monitor is built to withstand extreme pressure conditions and ensures durability and reliability in diverse operational environments. This robust construction makes it suitable for various applications, from laboratory settings to field deployments.

Absolute and Differential Pressure Ranges

The Fluke RPM4-AD covers both absolute and differential pressure ranges typical for air data instruments. This versatility makes it a valuable asset for aeronautical applications, catering to both fixed-wing and rotary-wing range versions. Whether calibrating altitude instruments or airspeed indicators, the RPM4-AD offers precise and reliable measurements.

Utilized Transfer Standard

In the calibration world, the reliability of measurements often hinges on the quality of the transfer standards used. The Fluke RPM4-AD employs a pressure monitor manufactured by DH Instruments Inc., known for its precision and resolution of 0.1 Pa. This ensures that the reference values obtained with the Fluke RPM4-AD are of the highest accuracy, meeting the stringent requirements of calibration procedures.

Operational Documentation

Fluke Calibration provides comprehensive operational and maintenance documentation to support users in harnessing the full potential of the RPM4-AD. This documentation aids technicians in understanding the instrument’s functionality, optimizing its use, and ensuring proper maintenance for prolonged reliability.
