Microtest 7120 Single-Phase Power Meter

The Microtest 7120 Single-Phase Power Meter covers a measurement range from 0.01 W to 16 kW with DC, 15 Hz to 100 kHz bandwidth, providing power measurement capability from standby power verification of consumer electronics to full-load efficiency testing of industrial equipment. The 0.01 W bottom of range is what makes the 7120 usable for standby power work, where the measured quantity is small enough that the instrument floor, not the load, sets what you can resolve.

Standby Power and Energy Efficiency

The instrument provides real-time readout of voltage, current, power, power factor, and frequency, while the optional harmonic analysis to the 50th order captures THD and individual harmonic content for power quality assessment. The DC, 15 Hz to 100 kHz bandwidth covers mains-frequency AC power through high-frequency switching converter analysis, making the 7120 versatile across power supply testing, lighting driver evaluation, motor efficiency measurement, and appliance energy rating verification.

Integration-Mode Measurement

Integration-mode power measurement averages over user-defined periods for accurate energy consumption testing of cyclical loads such as refrigerators, washing machines, and air conditioners where instantaneous power readings do not represent true energy consumption.

Applications

With India’s Bureau of Energy Efficiency (BEE) standards driving mandatory efficiency labeling across more product categories, the 7120 addresses a growing measurement need for Indian manufacturers. Appliance manufacturers, lighting companies, power supply producers, and energy efficiency testing laboratories all use the 7120 for compliance verification and product optimization.
