Current Loop Calibrators

A loop calibrator is a special-purpose electronic test instrument, it has been designed and manufactured to perform loop testing, circuit troubleshooting and calibration on current loops. These versatile tools are capable of not only measuring current, but also sourcing current to unpowered devices in a loop, as well as simulating the operation of loop-powered transmitters.


Over the years, loop calibrators have become more and more advanced, now offering users time-saving features, large menu graphics through a digital interface and microprocessor-based electronics. You can tailor your choice of calibrator, choosing from different brands, resolutions, power supply, operating temperatures and measurements - ensuring that you have exactly what you need.


RS Components offers some of the most prestige current loop calibrators, brought to you from market-leading brands such as Fluke, Druck, Time Electronic and of course our trusted own brand RS Pro.
