Fluke 744 Process Calibrator with HART

The 744 is a power multifunction documenting calibrator that lets you download procedures, lists, and instructions created with software-or upload data for printing, archiving, and analysis. The 744 also features a powerful built in HART® interface capable of performing nearly all the day-to-day tasks you now perform with a separate communicator.

Features

• Measure volts, mA, RTDs, thermocouples, frequency, and ohms to test sensors, transmitters and other instruments
• Source/simulate volts, mA, thermocouples, RTDs, frequency, ohms, and pressure to calibrate transmitters
• Power transmitters during test using loop supply with simultaneous mA measurement
• Measure/source pressure using any of 29 Fluke 700Pxx Pressure Modules
• Create and run automated as-found/as-left procedures to satisfy quality programs or regulations. Record and document results
• Holds up to a full week of downloaded procedures and calibration results
• Use many features like autostep, custom units, user entered values during test, one-point and two-point switch testing, square root DP flow testing, programmable measurement delay etc.
• Easy to use
• Three year warranty
• Bright white dual display. Read both sourced and measured parameters simultaneously.
