AEMC Instruments 2139.40 - 205 Clamp-on Power Meter - Single & 3-Phase Power, 600 ACA, 900 DCA, 1000 AC/DCV, True-RMS


The AEMC Instruments Model 205 True-RMS clamp-on meter is safety rated at 600V CAT IV. It measures AC+DC volts and amps, frequency, continuity, resistance, power and Power Factor, phase rotation, and THD. It can also perform diode checks. The Delta relative function compares new measurements to a reference value, and the MIN/MAX function tracks high and low values. The Model 205 also tracks peak+ and peak– values. This compact and rugged meter can operate in the most demanding work environments, and its IP40 rating allows it to withstand both dust and water spray.
