Ecom 725Ex Calibrator

The 725Ex is an intrinsically safe multifunction process calibrator that is both powerful and simple to operate. The calibrator can calibrate practically any process instrument that will need service in an ex-hazardous environment when used in conjunction with the 700PEx pressure modules.

The intrinsically safe calibrator is a versatile measuring tool for process technicians that may be used in a variety of situations.

Features:

• Class I, Division 1
• ATEX Zone 0 (II 1G EEx ia IIB 171°C)
• Two-channel simultaneous source and measure capability for calibration of transmitters
• Store frequently-used test setups for later use
• Power transmitters with internal loop supply
• Pressure switch test function to capture set, reset, and deadband values
• Pressure measurement to 3,000 psi/200 bar using any of the 8 intrinsically safe 700PEx Pressure Modules
• Measure volts dc, mA, RTDs, thermocouples, frequency, and ohms
