The Hioki 3169-20 and 3169-21 are Clamp On Power HiTesters that allow measurement of single-phase to three-phase 4-wire circuits with a single unit. In addition to measuring standard parameters such as voltage, current, power factor, and integrated values, these clamp-on power meters can simultaneously perform demand measurements required for carrying out power management and energy-saving measures, as well as harmonic measurements.
The 3169-20 and 3169-21 power meters also feature PC card data storage, and come equipped with an RS-232C interface for PC communications. Further, with grater data processing speeds, it is possible to measure the power of just a few cycles, enabling more detailed and effective energy-saving measures for equipment. The 3169-20 and 3169-21 are ideal for users who want to achieve close control over energy-saving management activities and measures.
