Product Overview
The Fluke 729 Automatic Pressure Calibrator is a portable, high-precision calibration tool designed to simplify pressure transmitter calibration for process technicians. Equipped with an internal electric pump, the device automatically generates and regulates pressure, eliminating manual pumping and reducing calibration time.
Users can simply enter a target pressure value, and the calibrator automatically pumps to and stabilizes at the desired setpoint using internal fine adjustment control. The instrument also supports automated multi-point pressure calibration tests and automatically documents results, allowing technicians to perform faster and more consistent calibrations.
The Fluke 729 combines pressure sourcing, measurement, and electrical signal testing. It can measure, source, and simulate 0 to 24 mA signals, supply 24V loop power, and features built-in HART communication for transmitter adjustment and configuration. With its rugged portable design (1-meter drop tested), graphical color display, and compatibility with DPCTrack2™ software, it is an ideal solution for field instrumentation maintenance.
Wireless "FC" models offer integration with the Fluke Connect® mobile app, enabling technicians to monitor measurements remotely and log data directly from the field.
