SPMK710 Digital Pressure Calibrator, With advanced microprocessor technology and high-tech silicon pressure sensors, the SPMK 710 digital pressure calibrator provides a pressure calibration solution for gauges, transmitters and pressure switches in a wide pressure range. In a highly protable package, it can measure pressure precisely with a built-in pressure sensor and read the current or mV produced by the transducer, and can even supply a drive voltage to power sensors or transmitters during calibration.
