The precision analog meter MR87 is a laboratory measuring instrument used for indicating one compatible electrical parameter through a calibrated scale and moving pointer. It is intended for students, teachers, technicians and equipment builders who need a continuously visible reading on physics trainers, circuit panels and supervised electrical experiment setups.
Product Description
The STEMAids Precision Analog Meter MR87 provides a mechanical pointer response to the electrical quantity supported by its confirmed configuration. When connected correctly, the pointer moves across the marked scale as the measured input changes. This continuous indication helps learners observe gradual variation, direction of change and approximate stability.
MR87 is a model or pattern designation rather than a complete measurement specification. The meter may be configured as an ammeter, voltmeter, galvanometer or another electrical indicator. Its measured quantity, range, scale unit, movement type, accuracy, internal resistance and mounting arrangement must be confirmed before publication or installation.

How to Use the Precision Analog Meter MR87
- Confirm the measured quantity, range and current type.
- Check the approved panel opening and mounting orientation.
- Switch off and isolate the circuit before installation.
- Secure the meter without applying pressure to its scale window.
- Connect the terminals according to the supplied wiring diagram.
- Install any specified shunt, multiplier or rectifying accessory.
- Energise the circuit and read the pointer against the correct scale.
- Switch off the circuit before altering any connection.
Safety note: Never determine the wiring method from the dial markings alone. Do not exceed the confirmed current, voltage, insulation or overload rating, and do not use the meter on mains circuits without documented suitability.
Care & Maintenance
- Clean the scale window with a soft, dry cloth.
- Protect the pointer movement from shock, vibration and overload.
- Inspect terminals and mounting hardware periodically.
- Store unused meters in a dry, dust-free environment.

Frequently Asked Questions
What is a precision analog meter MR87 used for?
It is used to indicate one compatible electrical parameter through a moving pointer and calibrated scale.
What does MR87 mean?
MR87 is a model or pattern designation associated with an analog meter format. It does not independently identify the electrical range or function.
Is the MR87 an ammeter, voltmeter or galvanometer?
Any of these configurations may be possible. The supplied scale, movement and internal circuitry determine the actual function.
Can it measure both AC and DC?
AC/DC compatibility is not established by the product name. Confirm the approved current type and wiring arrangement before use.
Does it require an external shunt or multiplier?
Some current and voltage ranges require external components. The verified range and connection diagram determine whether these accessories are necessary.
Is it suitable for school laboratories?
Yes, when installed on a protected instructional panel and operated within its confirmed electrical range under supervision.
