The 220 is a highly integrated loop calibrator featuring several patented technologies, the calibrator is an ultra-compact, rugged, and best of all, easy to use hand-held device that will source, simulate and measure loop current, mV/V, loop integrity, and also perform switch testing. Its smart phone-like menu and interface makes it simple and easy to use. The 220 is ideal for calibrating, maintaining, and troubleshooting various loop devices in the field.

  • Measuring and Sourcing loop current, mV, and V
  • Measuring and sourcing simultaneously
  • Loop integrity check capability
  • 24V loop supply with simultaneous current measurement

The 220 loop calibrator is a process tool for measuring, sourcing and simulating mA, mV and V, captures switch values and provides 24 V loop power. It is a high performance solution for calibration, repair and maintenance of various loops devices, loop integrity check, and switch capture.
