The ITECH IT9121E is a high-performance digital power meter designed for measuring voltage, current, power, frequency, harmonics (up to the 50th order), and overall power quality. It supports inputs up to 600 V RMS and 20 A RMS, with a measurement bandwidth reaching 100 kHz — ideal for high-frequency and precision testing of motors, appliances, and UPS systems..
The IT9121E is designed for comprehensive power quality and performance analysis. With its high bandwidth, it captures transient and high-frequency components that typical meters might miss. It excels in demanding environments such as motor testing, appliance characterization, and grid systems. Its built-in harmonics analysis (up to 50th order) and energy accumulation functions aid in in-depth electrical performance evaluation and compliance testing. The customizable display matrix enables simultaneous visualization of multiple parameters, and recorded data can be stored via USB or accessed through LAN/RS‑232/GPIB interfaces.
