Fluke 719Pro combines an electric pneumatic pump, pressure measurement and a full loop calibrator. The large backlit screen displays three parameters at once: internal or external pressure, an mA signal and temperature from an optional RTD probe. The 30G, 150G and 300G versions serve different ranges. The instrument measures, sources and simulates current, checks DC voltage up to 30 V and supplies 24 V loop power. The internal system requires dry air and non-corrosive gas. Select the 720RTD probe and compatible external pressure modules separately.
