Application
A mounting-type electric meter is a direct-acting, indicating, analogue electrical-measuring instrument with a wide application range. It is applicable for the measurement of DC circuits and power frequency AC circuits: electric parameters such as voltage, current, frequency, power factor, synchronous indication, etc. Intrinsic advantages of mounting panel meter: display the change trend of measured electric quantity, in addition to single use, it is mainly matched with instrument board for various HV and LV switch gears, power cabinets, control cabinets, as well as various electrical control devices, its indexes are in accordance with the technical requirements of national standard GB/T7676-1998.
It is featured with plastic or bakelite housing, a large window, a wide visual angle, laconic and lucid construction, elegant appearance, etc.
