MR66 Moving Coil Meter Manufacturer,Supplier and Exporter in India
Product Code : SCL-LM-11291
The MR66 Moving Coil Meter uses a moving-coil indicating mechanism to produce pointer deflection in response to an electrical input. Its linear scale allows students to read measured values and observe gradual changes during current, voltage, resistance and electromagnetic induction experiments.
The meter is housed in an ABS plastic cabinet and fitted with brass connection terminals. A 65 mm scale, clear dial markings and a knife-edge pointer support convenient classroom observation. The instrument is available in ammeter, voltmeter and centre-zero galvanometer configurations with the required range selected at the time of ordering.
Key Features
65 mm scale: Provides a clear reading area for individual practical work and classroom demonstrations.
Moving-coil mechanism: Produces responsive analog indication for compatible DC measurements.
Multiple configurations: Available as an ammeter, voltmeter or centre-zero galvanometer.
ABS plastic cabinet: Protects the internal meter movement during normal laboratory handling.
Brass terminals: Permit straightforward connection to educational circuits and test leads.
Knife-edge pointer: Supports more precise alignment with the graduated scale.
Mechanical zero adjustment: Allows the pointer to be checked and adjusted before use.
Educational design: Suitable for repeated supervised use in physics and electrical laboratories.

How to Use the MR66 Moving Coil Meter
Identify whether the meter is configured as an ammeter, voltmeter or galvanometer.
Confirm the marked measuring range before connecting it to the circuit.
Disconnect the circuit supply and check that the pointer rests at zero.
Use the mechanical adjuster if a small zero correction is required.
Connect an ammeter in series or a voltmeter in parallel with the component.
Observe the correct terminal polarity for DC measurement.
Apply power and read the pointer directly in front of the scale.
Switch off the supply before altering or disconnecting the circuit.
Safety note: Do not exceed the marked measuring range. Never connect an ammeter directly across a power source, as excessive current may damage the meter movement.
Care & Maintenance
Store the meter in a dry, dust-free cabinet when it is not in use.
Clean the cover with a soft cloth without applying pressure to the scale window.
Protect the instrument from impact, vibration, moisture and strong magnetic fields.
Inspect terminals and connecting leads before every laboratory session.
