The Hioki 3169-21 Power HiTester is a handheld clamp-on device to test and analyse electrical circuits.

The compact power meter can simultaneously perform demand measurements required for carrying out power management and energy-saving measures, as well as harmonic measurements.

The device is capable of testing voltage, current, active power, reactive power, apparent power, power factor, integrated value, frequency and harmonics. It measures voltages between 150 and 600 V in three ranges and measures up to two three-phase, 3-wire systems and up to four single-phase, 2-wire systems.

The device features a 5-5000 A measurement range, PC card data storage and simultaneous recording of demand values and harmonics. It is supplied with power measurement support software that provides quick and easy transfer of data from the unit to a PC for simple graphical processing and analysis.
