Description
Moving iron panel meters, EQ 48/72/96/144 n sizes are suitable for measurement of AC current & voltage in usual frequency range of
15 - 100 Hz & above 100 Hz. EQ..n meters are protected from breakage under adverses condition because of it suspended between
spring loaded saphire jewl & critical damped using. Silicon oil which protect meters from breakage under adverse condition
Features
1. Housed in glass filed polycarbonate cases.
2. Indicates true RMS value practically independent of waveform even of high harmonics.
3. Large torque to weight ratio which assures a long life of instrument.
4. Standard terminal covers IP 10. Complete protection cover on request.
5. CT operated meters has onsite interchangeable scale facility. Provision for easy replacement of front window, glass & bezel.
