UNI-T UT243 Power and Harmonics Clamp Meter
The UNI-T UT243 Power and Harmonics Clamp Meter is a professional handheld electrical measurement instrument designed for analyzing power consumption and electrical system performance. Its clamp-style current measurement allows technicians to measure current without disconnecting the conductor, while the meter provides multiple electrical parameters useful for troubleshooting, maintenance, and energy analysis.
The UT243 is particularly useful for industrial electrical systems, distribution panels, motors, generators, and other power equipment where power quality and harmonic conditions need to be evaluated. Its combination of clamp current measurement and power-analysis functions makes it suitable for electricians, maintenance technicians, electrical engineers, and service professionals.
