ITECH IT9121


ITECH IT9121 Power Meter

The ITECH IT9121 power meter can provide the maximum input of 600Vrms and 20Arms and measurement bandwidth of 100KHZ, and can be easily used for measuring the voltage, current, power, frequency, harmonics and other parameters. The standard configuration includes USB, GPIB, RS232 and LAN communication interfaces and also interfaces for USB-based peripheral devices. The user can save the measured parameters into the external storage medium. The basic voltage and current accuracy is 0.1%. Moreover, the power meter has rich integrating functions, such as the active power. It is widely applied in test of motors, household appliances, UPS, etc.

Oscilloscope function

It can display the waveform basing on sampling data. You can chose to display or hide the waveform of the input voltage and current.

Harmonic measurement

The IT9121 has a bandwidth of 100KHz, which can realize high-speed harmonic measurement within a wider dynamic range. In the harmonic mode, the voltage, the current, the active power, reactive power and phase of each harmonic and the factor of total harmonic distortion (THD) can be tested. In addition, IT9121 can be used for measurement of multiple harmonics, 50 harmonics of the fundamental frequency can be measured at most. The parameters of each harmonic measured by the IT9121 can be displayed in the bar chart and the list, so as to facilitate analysis of measurement results.
