    FLUKE 721-1650 Dual Sensor Pressure Calibrator; 1.1 bar; 345 bar

    # 721-1650

    • 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
