The Fluke 721 boasts two isolated stainless steel, pressure sensors with an accuracy of 0.025%, with the capability off performing pitch tests on both pressure inputs.

The Fluke 721 displays pressure in user choice of 19 engineering units, alongside an optional Pt100 RTD probe temperature measurements can be performed. Perform mA signal measurements from 4 to 20mA. The internal 24V loop power supply can power a transmitter under test. It is possible to extend the pressure measurement range of the Fluke 721 by connecting the device to one of the 50 external 750 series pressure modules from 0 to 1 in H20 to 10,000 psi (2.5 mBar to 690 bar).

With a large backlit graphical display, the Fluke 721 can display three inputs simultaneously and store up to five instrument set ups for recall and use. Powered by four standard AA batteries, the Fluke 721 has a battery life of up to 35 hours.

Fluke Premium Care Plan

With Fluke Premium Care Plans, the aim is to reduce the cost of ownership of the Fluke 721 Dual Sensor Precision Pressure Calibrator by eliminating the service and support charges.
