Fluke 721-3650 Dual Sensor Pressure Calibrator 36PSIG/5000PSIG

The Fluke 721-3650 is a high-accuracy dual sensor pressure calibrator engineered for demanding industrial environments. Ideal for gas flow calibration and custody transfer applications, this handheld calibrator combines two isolated stainless steel pressure sensors with 0.025% accuracy, a Pt100 RTD input for temperature measurement, and the ability to measure 4-20 mA signals. Its internal 24 V loop power supply allows you to power transmitters under test, while the large backlit graphic display shows up to three inputs simultaneously.
