The Fluke 700PA4 Absolute Pressure Module displays pressure readings in any of 10 different pressure units you specify in the calibrator setup. The pressure module allows you to measure absolute pressure with the Fluke 740 Series Documenting Process Calibrators. The modules have one fitting and measure pressure with respect to an absolute vacuum. The pressure module measures pressure using an internal microprocessor. It receives operating power from and sends digital information to the calibrator. It features internal temperature compensation from 0 to 50 Degree Celsius for full-accuracy performance. The 700PA4 is compatible only with the 740 Series Calibrators. The module can be calibrated locally using the Fluke 700PCK Pressure Calibration Kit at ambient temperature with a precision pressure calibrator or dead weight tester. A vacuum source is required. The unit's rugged urethane molded case protects the module from rough handling and harsh conditions. The 700PA4 includes: pressure module, strap, one 1/4 NPT to 1/4 ISO metric adapters, NIST-traceable calibration certificate and instruction sheet.
