 | Moving Iron & Moving Coil Meters | | |
| Moving Iron Instruments are generally used for measuring AC Voltage and Currents. A feature of the moving element is that it is fitted with synthetic sapphire jewels. The movement is light and quick acting, but extremely robust. An efficient system of fluid damping is employed. The movement is efficiently shielded against the effect of external magnetic fields.
Moving Coil Instruments are used for measuring DC values. They can be used too on AC systems, if the input is fed through bridge rectifiers. A Center magnet system is incorporated in our moving coil instruments which completely shields the movement from the effect of external magnetic fields. The movement is pivoted between synthetic sapphire jewel bearings for frictionless operation.
The above meters can be used for higher ranges by using necessary CTs/PTs and external shunts, which are also manufactured and offered by us.
Accuracy Class: 1 to 1.5% as per ISS 1248/83.
MOVING IRON AMMETERS
Range: 50mA to 100A Self contained and higher ranges via current transformers, with secondary 1A or 5A.Overload scales 2.3 or 4 & 6 times rated load can be provided.
MOVING IRON VOLTMETERS
Range: 50V to 600V Self contained and higher ranges by use of PTs.
MOVING COIL AMMETERS
Range: 50 µA to 30A Self contained and external shunt operated for higher ranges.
MOVING COIL VOLTMETERS
Range: 50mV to 600V Self contained and higher ranges by use of external resistance box.

| Bimetallic Maximum Demand Meter | | |
| NIPPEN Bimetallic maximum demand ammeters with integration time of 15min. find special use in panels. There are two models to choose from. Model MD-96 has a slave pointer attached to the bimetal movement. In Model MD-96S the instantaneous values can also be monitored in addition to the maximum demand values, by the additional moving iron movement. |

| Frequency Meters | | |
| | NIPPEN's Frequency Meters are of two types : | | 1) Vibrating Reed Type Frequency Meters
| | | 2) Transducer type, Pointer Frequency Meters | |
| | | Vibrating reed type frequency meter | | | The vibrating reed frequency meter has steel reed elements in the field of an electromagnet. The reeds vibrate in resonance with the energizing Alternating Current of this electromagnet. Meters are manufactured having 11, 13 or 21 reeds. 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. | | | | Available in sizes: 72mm, 96mm & 144mm square panel mounting type. | | | | Range: 45-50-55 Hz, 47-50-53 Hz | | | | Voltage: 110V or 230V or 440V | | | | Accuracy: ± 1% as per ISS 1248/83 | |
| Phase Sequency Meters | | |
| These meters measure sequences of 3 phase power lines. Suitable for operating on 50-500V AC and 40-65Hz, they are housed in 96mm square cases. The phase sequence is indicated by the direction of rotation of the disc. |
|
| Insulation Testers | | |
| Insulation Testers are used for direct reading of insulation resistance of electrical rotating machines, power distribution lines, communication cables, insulators, control and switching equipment etc. They are robust instruments, incorporating a built-in-hand driven generator and a solid-state circuit for a stabilized D.C. output. |
| Earth Tester | | |
NIPPEN Earth Resistance Testers are used for measuring of earth electrode resistance, soil resistance, earth continuity, neutral and earth loop resistance, resistance of various components etc.
Useful for Railways, Defence, Electricity Boards, Power Generating Plants, Geological Surveyors, Industries etc.
Four terminal measurement system avoids errors due to spike and testing wires resistance.
Direct reading type models SET/DET/TET provide direct readings of resistance on a moving coil type of meters having linear scale, 70mm long knife edge pointer and external zero adjustment. |
