Fluke 725 Multifunction
Calibrator
Simply Powerful!
The new Fluke 725 Multifunction Process
Calibrator is a powerful yet easy-to-use field
calibrator. Use the measure and source functions
to test and calibrate almost any process
parameter.
•Small, streamlined shape makes it easy
to carry
•Rugged, reliable design stands up to field use
•Easy to read measure/source screen lets you
view input and output simultaneously
•Measure volts, mA, RTDs, thermocouples,
frequency, and ohms to test sensors and
transmitters
•Source/simulate volts, mA, thermocouples, RTDs,
frequency, and ohms to calibrate transmitters
•Measure/source pressure using any of 28
Fluke 700Pxx Pressure Modules
•Source mA with simultaneous pressure
measurement to conduct valve and I/P tests
•Support flow meter testing with frequency
and CPM functions
•Perform fast linearity tests with auto step and
auto ramp features
•Power transmitters during test using loop
supply with simultaneous mA measurement
•Store frequently-used test setups for later use
•Backlight lets you work in poor light
•Remote interface allows benchtop automated
operations
•Large battery capacity of four AA cells
•Battery door for easy changes
