These are Moving Coil DC, Moving Coil rectifier type AC, Moving Iron AC ammeters & voltmeters which are suitable for use in school, laboratories, workshops & for field operation. Specially designed to be operated in horizontal position (also in inclined position upto 45°) & can be carried along safely.

Moving Iron Instruments are protected from damage or breakage under adverse condition due to its spring loaded jewel & pivot system. These Instruments are free from external magnetic field influences because of magnetic shielding & are ‘CE’ certified. These instruments have a very efficient oil damping system, which gives almost a deadbeat movement to the pointer, without irksome oscillation. The movement is light yet sturdy and has a large torque to weight ratio which assures long life to instruments.

These indicate true RMS values practically independent of waveform even of high harmonics. The scale is compressed initially. Readability starts from 10 to 15 degree approximately.

Features :

• Scale : Non-linear.
• Suppression : Initial suppression for Voltmeter & End suppression upto 6 times for Ammeter. (on request)
• Scale Colour : Special colour scales and marks for different ranges, (on request).
• Housing : Engineering plastic.
• Terminal Protection : Shrouded terminals to protect from accident, (on request).
• Glass : Anti – glare. (on request)

Moving coil instruments with circular scale of 240° employ a platinum taut band for suspension of moving coil assembly instead of pivot & jewel system. It is less prone to sluggishness & zero shift due to frictionless movement.

These meters are basically used for the measurement of DC current & voltage, and can be used with built in rectifier for the measurement of AC current & voltage in the frequency range 45~65Hz. / 400Hz. The meters measure average value. It can be scaled to indicate RMS values (on request).

These instruments are not recommended for non-sinusoidal waveforms of current & voltage. The other indications like Frequency, Power & Power factor can be offered with suitable external transducers. Speed indication is possible if used with AC tacho-generator (not in the scope of AE).

These are Moving Coil or Moving Iron type instruments or dynamometric type instruments, specially designed to be operated in horizontal position (also in inclined position upto 45°) & can be carried along safely.

Features :

• Instruments with 0.5% accuracy class.
• Instruments with multiple scale available (refer table).
• Robust housing suitable for schools, workshops, field operations for continuous use.
• Precision instruments suitable for standard laboratories (Size: 1).
