AC Ammeter and Voltmeter
>Measuring the alternative current or voltage,moving iron movement,indicating ture RMS values.
The symbol letter is T
The accuracy cl is 1.5.
stand for dire conneing accuracy 2.5
>Meeting the standard of GB/T7676-1998 and IEC60051.
In addition,AL series(48×48,72×72,96×96）
The Advantages of Our Produs
Interehangeable Dial
>Changing the dial without openning the meter.
Under the same seme secondary current,the dial of AC ammeter can be changed,no loss of accuracy.(48×48 model must have same scale division）.
