Description
Fluke 721-3601 Offers
Features
Two isolated, stainless steel, pressure sensors with 0.025% f.s. accuracy
Can be configured by selecting either a 16 psig (1.1 bar) or 36 psig (2.48 bar) low pressure sensor and then adding your choice of 7 high pressure ranges
External pressure module connection supports all pressure modules (29 ranges) for even more measurement capability
Temperature-compensation ensures accuracy in field applications
Pt100 RTD input for temperature measurement, accurate to 0.1°C (0.2°F) (Requires optional RTD probe sold separately)
Measure 4-20 mA signals
Internal 24 V Loop Power Supply can power a transmitter under test
Measure up to 30 V DC
Large graphic style LCD with backlight can be configured to display up to 3 inputs simultaneously (i.e. pressure 1, pressure 2, and RTD or any combination of inputs)
Pressure displayed in the user’s choice of 19 engineering units
Switch test on both pressure inputs, or external pressure module
Operating mode layers support simple measurements to complex applications
Up to five frequently used setups can be stored; last setup automatically recalled on power-up
