Portable and handheld test instruments like the current clamp probe and portable power meter from Yokogawa Test&Measurement are important parts of the field technician or engineer’s toolkit. This is due to their flexibility, ruggedness in harsh environments, and varied functionality to handle anything from simple measurements to power quality analysis and pressure calibration. They can log data quickly to internal memory, as well as perform quick measurements for easy troubleshooting of industrial field equipment. Often, it is both impractical and cost-ineffective to bring lab-grade instruments into the field where such precision is neither warranted nor needed. Portable test equipment is ideal for closing that needed gap.
