the Fluke 725 Multifunction Process Calibrator, and you're equipped to test and calibrate almost any process parameter. Measure and source mA, volts, temperature (RTDs and thermocouples), frequency, ohms, and pressure, using optional pressure modules. Do you need to calibrate transmitters? The 725's split display lets you view input and output values simultaneously. For valve and IP tests, you can source mA while measuring pressure. The 725 has auto-stepping and auto-ramping for remote testing, plus 25% stepping for fast linearity tests.
