The vibrating reed frequency meter has steel reed elements placed in the field of an electromagnet. The reeds vibrate in resonance with the energizing Alternating Current of this electromagnet.Only the individual reed, whose natural frequency corresponds with the frequency of the A.C. supply, will vibrate at full amplitude indicating the correct frequency on the dial. When two reeds show deflection of the same amplitude the mean of the two gives the correct frequency.

We have three type of portable meters :-1. Wooden box type.2. ABS Educational desk stand type3. Metallic Educational desk stand type
Wooden box type PortablesThese meters are heavy and sturdy meters. These type of Portable Ammeters and voltmeters are designed for use in the field test rooms and laboratories, where precise measurement is required. These portable Instruments can be used equally well in educational institutions, where there is possible misuse; and in factories, where these instruments are important for making calibration check on switchboard panel instruments.These are manufactured under rigid quality control to ensure stable performance and durability.
These are available in moving iron & moving coil type.
