Fluke Dual Sensor Pressure Calibrator 36 to 3000 PSIG Model FLUKE 721

Description

Product Overview

The Fluke Dual Sensor Pressure Calibrator is engineered for professionals who demand uncompromising precision in pressure measurement. Featuring two isolated stainless‑steel sensors, the unit achieves a remarkable 0.025% accuracy across a wide range of 36 to 3000 PSIG, making it suitable for both low‑pressure gas flow checks and high‑pressure industrial verification tasks. Its robust housing protects internal components from harsh field conditions while maintaining a compact form factor that fits comfortably in a technician’s toolbox.

Designed with user‑friendly ergonomics, the calibrator includes an intuitive digital display that presents pressure readings, units, and diagnostic information at a glance. The device operates on four AA alkaline batteries, which are supplied in the package, ensuring immediate readiness out of the box. Battery life is optimized for extended field work, allowing multiple calibrations to be performed before a recharge is needed.

Beyond its core measurement capabilities, the calibrator offers expandable functionality through optional external 700 series pressure modules. These modules extend the pressure range and provide additional range selections, giving users the flexibility to adapt the instrument to a variety of specialized applications without purchasing a separate device.

Data management is streamlined with the ability to store up to five distinct instrument setups. Each setup captures sensor configuration, range, and calibration constants, enabling rapid recall and reducing the time spent re‑entering parameters for recurring tasks. This feature is especially valuable in environments where multiple pieces of equipment require frequent verification.

Fluke’s reputation for durability is reflected in the calibrator’s construction. The device meets rigorous industrial standards, and its components are selected for long‑term stability, minimizing drift over time. This reliability translates into lower total cost of ownership, as users can trust the instrument’s performance throughout its service life.

Overall, the Fluke Dual Sensor Pressure Calibrator combines high‑accuracy measurement, versatile range options, and practical field features into a single, portable solution that addresses the demanding needs of gas flow calibration, custody transfer verification, and general pressure testing.

Usage

In refinery environments, technicians rely on the calibrator to verify pressure transmitters that control critical process streams. The device’s rugged design withstands the temperature fluctuations and vibration typical of such settings, while its battery‑powered operation eliminates the need for external power sources, allowing quick spot checks on the shop floor.

Utility companies employ the calibrator for custody transfer applications, where accurate measurement of gas volumes is essential for billing and regulatory compliance. The dual‑sensor architecture provides redundancy, ensuring that any single sensor deviation is immediately identified, thereby safeguarding the integrity of the measurement process.

Laboratory engineers use the instrument for routine calibration of pressure gauges and pneumatic equipment. The ability to store multiple setups means that a single calibrator can service a range of devices, from low‑pressure laboratory instruments to high‑pressure field equipment, without reconfiguration delays.

Field service professionals benefit from the portable nature of the calibrator when performing on‑site maintenance for HVAC systems, compressors, and pneumatic control valves. The clear display and straightforward controls reduce training time, enabling technicians to perform accurate calibrations even in confined or remote locations.
