Multifunction Process Calibrator

Информация

The 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.
• Compact, 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 25% and
100% steps
• Execute remote tests with auto step and auto
ramp
• 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
