Fluke 718 300G High-Range Pressure Calibrator 12 PSI to 300 Essential Testing Equipment

Description

The Fluke 718 300G is a compact, self-contained pneumatic pressure calibrator designed for precision calibration and maintenance of transmitters, switches, and gauges in demanding process environments. Featuring Original Engineering by Fluke, this instrument integrates an internal pressure/vacuum hand pump, precision pressure sensor, and milliamp loop measurement circuit into a single handheld unit, eliminating the requirement to carry external gas bottles or auxiliary calibration pumps into the field.

Technical Compatibility and System Integration:
The Fluke 718 300G provides full Technical Compatibility with the Fluke 750P and legacy 700P Series pressure modules, allowing scaling across differential, gage, absolute, and high-pressure ranges up to 10,000 PSI. Integrated switch-test functionality automates setpoint, reset point, and deadband detection on mechanical pressure switches. The unit also includes cleanout ports that allow field technicians to flush moisture or fluid contaminants out of the pump chamber without disassembling the device or invalidating factory calibration.

Industrial Application Scenario:
In oil and gas processing plants, chemical refining facilities, and utility boiler installations, instrumentation engineers face critical challenges when verifying 4-20 mA pressure transmitters located on remote pipe racks or elevated valve skids. Carrying heavy nitrogen cylinders or multiple separate instruments to perform routine calibration creates safety hazards and logistical bottlenecks. The Fluke 718 300G resolves this operational issue by allowing a single technician to isolate the process transmitter, generate accurate test pressures up to 300 PSI using the vernier micro-adjust hand pump, supply 24 V loop power, and simultaneously measure the loop output current with 0.05% precision directly at the installation point.
