Dual-sensor pressure calibrator with 16 PSIG and 1000 PSIG ranges, 0.025% accuracy, RTD input, and support for external pressure modules—ideal for custody transfer and gas flow calibration.
Fluke 721-1610 Dual Sensor Pressure Calibrator 16 PSIG, 1000 PSIG
The Fluke 721-1610 Dual Sensor Pressure Calibrator is built for high-accuracy pressure measurement and calibration, particularly in custody transfer and gas flow applications. Featuring two isolated stainless steel sensors rated at 16 PSIG and 1000 PSIG with 0.025% of full-scale accuracy, this calibrator is designed to handle both low- and high-pressure tasks with confidence.
It supports a Pt100 RTD input for temperature measurement, and includes functionality to measure 4–20 mA signals, check 24 V loop power supplies, and display up to three inputs simultaneously on its large backlit screen. Expandable via Fluke 700 Series external pressure modules, the 721-1610 offers unmatched flexibility in field calibration tasks.
