Power Analyzer/ Power Meter

MICROTEST 7140 Power Analyzer is designed for precise single-phase AC/DC power measurement, with a bandwidth of DC, 0.2Hz to 100kHz and a 500kSPS sampling rate. It offers ±0.05% power measurement accuracy and supports a direct input voltage of 800V and current of 30A. With 100-harmonic analysis capability, it allows simultaneous harmonic analysis and integration, improving testing efficiency. The 4.3" TFT LCD provides clear numerical and graphical displays, including waveform, bar charts, and trend graphs. It also supports low-current measurements down to 5mA and 10μW resolution, making it ideal for production lines, R&D, and quality control.

MICROTEST 7130 is a High-Precision Power Meter designed for single-phase AC/DC measurements with a 0.2Hz–100kHz bandwidth and 500kSPS sampling rate. It delivers ±0.05% accuracy in a compact design with a 4.3” TFT LCD. Supporting 800V/30A direct input and 50th-order harmonic analysis, the independent measurement module enables simultaneous harmonic analysis and integration measurement for real-time power quality monitoring. The built-in graphical display provides oscilloscope-like waveform observation, while the USB Host allows direct waveform capture and data logging—no external oscilloscope needed.
