Application£º
Adopting the up-to-date MPU technology produces it, and it is designed by making use of the high precision, wide measure range digital electricity energy cmos chip. It has the characteristic, such as the high precision, wide measure range, high reliability and low expense. The shape of the series is elegant and sober, which is adopted the special LCD or high light special LED to show. At the same time, it adopts the army using part to produce which helps it also develop the characteristic of long use life, free service and convenient copying. It can measure by the clockwise and anti-clockwise, guarding against theft. It provides the impulse output to benefit user measure or form the centralized copying ammeters system. It has been the excellent product of national extending sharing-time price policy.
