Product Overview

The Fluke 719-100G​ is a professional-grade, portable pressure calibrator designed for field and workshop calibration of pressure instruments. It is a key member of Fluke’s renowned 100G Series of pressure calibration tools, which are engineered for accuracy, durability, and ease of use. The 719-100G​ combines a high-accuracy pressure measurement capability with an integrated, precision hand pump, allowing technicians to both generate and measure pressure within a single, compact unit. Its primary function is to serve as a portable standard for calibrating, testing, and troubleshooting a wide array of pressure devices, including mechanical pressure gauges, pressure switches, transmitters, and other process instrumentation. The “G” in its model number signifies that it is a gas-operated (pneumatic) calibrator, with the integrated pump designed to use clean, dry air or an inert gas like nitrogen to generate pressure up to 30 psi (approximately 2 bar).This calibrator is built around a high-stability pressure sensor and a microprocessor-based digital readout, providing clear, reliable measurement of the applied pressure. The Fluke 719-100G​ excels in its role as a troubleshooting tool, allowing technicians to quickly simulate process pressure conditions, verify switch setpoints, and check the linearity and accuracy of gauges and transmitters on-site, minimizing equipment downtime. Its value proposition lies in combining laboratory-grade accuracy in a rugged, portable package suitable for harsh industrial environments. By eliminating the need to transport bulky test stands or multiple instruments to a job site, the 719-100G​ significantly improves the efficiency of calibration and maintenance workflows for instrumentation technicians across industries such as oil and gas, water treatment, manufacturing, and HVAC. It represents a practical, reliable solution for ensuring that pressure measurements throughout a facility are accurate and trustworthy, which is fundamental for process safety, quality control, and regulatory compliance.

Technical Specifications

Main Features and Advantages

All-in-One Portability and Simplicity: The most significant advantage of the Fluke 719-100G​ is its integrated, self-contained design. The combination of a precision measurement gauge and a fine-control generation pump in one handheld tool means a technician can perform a complete pressure calibration with a single instrument. The manual pump provides excellent control for slowly ramping pressure up and down, which is essential for accurately determining setpoints of pressure switches and checking for hysteresis in gauges. This integrated approach saves time, reduces the number of tools needed in the field, and minimizes potential leak points compared to using separate pumps and gauges.High Accuracy and Versatile Functionality: Despite its portable nature, the 719-100G​ delivers metrology-grade accuracy suitable for calibrating working instruments in industrial settings. Its high-resolution display allows for precise reading of pressure values. A key feature that extends its utility beyond simple gauge checking is the integrated 0/4-20 mA measure and source capability. This allows the technician to use the calibrator to simultaneously measure the pressure output of the pump andthe corresponding mA output signal from a pressure transmitter, or to source a mA signal to simulate a transmitter for testing a PLC input or indicator. This makes the Fluke 719-100G​ an indispensable tool for loop calibration and troubleshooting. The rugged construction, clear display, and intuitive operation make it reliable and easy to use even in challenging plant environments, ensuring that calibrations are performed correctly and efficiently every time.
