Fluke 721Ex

Fluke Precision Pressure Calibrator
- Precision Pressure Calibrator with dual isolated sensors for gas custody transfer applications.
Description

Features:

The 721Ex can be configured by selecting either a 16 PSI (1.1 bar) or 36 psi (2.48 bar) low pressure sensor then add any of 7 high pressure ranges including 100, 300, 500, 1000, 1500, 3000 or 5000 psi (6.9, 20, 24.5, 69, 103.4, 200, 345 bar).

  • Intrinsically Safe – IECEx and Atex Ex ia IIB T3 Gb (Zone 1) rated 
  • Ideal for gas flow calibration (custody transfer) applications
  • Two isolated, stainless steel, pressure sensors with 0.025 % accuracy
  • Pt100 RTD input for temperature measurement, (probe optional)
  • Switch test on both pressure inputs
  • Pressure displayed in the user’s choice of 19 engineering units
  • Large backlit graphic display can display up to three inputs simultaneously
  • Store five instrument setups for recall and use
