A powerful tool calibration intrinsically safe
The new Multifunction Process Calibrator Fluke intrinsically safe 725Ex is powerful and easy to use. Combined with the new Fluke pressure modules 700PEx the 725Ex calibrates most process instrumentation may require an intervention in an area where the presence of explosive gases is not excluded.
Measure and milliamps, volts, temperature (RTDs and thermocouples), frequency, ohms, and pressure, using optional pressure modules.
You need to calibrate transmitters? The display of the subdivided model 725 allows you to simultaneously view the input values and output. To test the valve and I / P, you can generate currents (mA) while measuring pressure. The 725 has functions of automatic step and ramp automatic remote testing, plus a step of 25% for fast linearity tests.
Once you take hold of the Fluke 725, it is ready for operation. Its simple controls, without menus, make operation very easy. Its memory functions make setup fast.
Use of generation and measurement functions to test and calibrate most process parameters. The intrinsically safe calibrator Fluke 725Ex a calibration solution is powerful, intrinsically safe multifunction has the following characteristics:
- ATEX II 1G EEx ia IIB 171 ° C
- Compliance IS Class I, Division 1 Groups BD, 171 ° C.
- Action: DC volts, mA, RTDs, thermocouples, frequency and ohms.
