Fluke 725 Multifunction Process Calibrator

I use one of these at work everyday. I would hate to be without it. I use almost every feature on it from 4-20 ma sourcing to simulating RTD's to sourcing in a freq signal. The only thing I have ever had a problem with is sometime I run across some digital inputs that require a frequency at a higher amplitude than the 5 volts peak to peak that this puts out. I have a small amplifier that I use to bring it up to 8 volts. It is rare that I need it though.

Have used in the past and never had a problem. They are pricey but work as advertised. When a process calibrator is needed this is the one.
