Fluke 721 Pressure Calibration Instruments
Product overview
Fluke 721 Precision Pressure Calibrator provides pressure calibration and temperature measurement for custody transfer applications
The Fluke 721 Precision Pressure Calibrator is the ideal tool for gas custody transfer applications. It features dual isolated pressure sensors to allow you to take simultaneous static and differential pressure measurements with a single tool. And it can be configured by selecting either a 16 psi (1.1 bar) or 36 psi (2.48 bar) low pressure sensor then adding any of seven high pressure ranges: 100, 300, 500, 1000, 1500, 3000 or 5000 psi (6.9, 20, 24.5, 69, 103.4, 200, 345 bar).
Other useful features:
- Measures up to 30 V DC, checks 24 V loop power supplies
- Extends pressure measurement range with connection to external 750P
- 750 series pressure modules (50 ranges)
- Provides a large backlit graphic display that can show up to three inputs simultaneously
- Stores five instrument setups for recall
