Tính năng Máy hiệu chuẩn áp suất Fluke 721-1601:

The 721 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). 

• 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)
• Measures 4 to 20 mA signals
• Internal 24 V loop power supply can power a transmitter under test
• Measure up to 30 V dc, check 24 V loop power supplies
• Extend pressure measurement range with connection to external 700 series pressure modules (29 ranges)
• Large backlit graphic display can display up to three inputs simultaneously
• Store five instrument setups for recall and use
