Precision Analog Meter MR87

Quick Answer: The Precision Analog Meter MR87 is an analog moving-pointer meter that indicates one electrical parameter on a calibrated scale, built in the MR87 case format. LabEquip can confirm the exact measured quantity, range, accuracy class and dimensions for this model before you order — “Precision” here is a product-line name, and any specific accuracy figure should be confirmed rather than assumed.

Description

This meter gives a mechanical pointer response to the electrical quantity supported by its confirmed configuration: as the measured input changes, the pointer moves across the marked scale, letting learners observe gradual variation, direction of change and approximate stability in real time. It uses the MR87 case format, which is a different physical pattern from the MR66 format used on some of our other analog meters, so mounting dimensions should be confirmed separately for each.

Please confirm with our sales team exactly which electrical quantity, measurement range and accuracy class apply to this specific unit before specifying it for calibrated or precision-sensitive work — we will not guess at figures that are not confirmed.

Specifications

Care & Maintenance

• Avoid mechanical shocks and drops, which can bend the pointer or affect calibration.
• Do not exceed the rated input for the confirmed measured quantity and range.
• Keep the meter face and terminals clean and free of dust.
• Mount and store the instrument so the pointer is not obstructed and the scale stays readable.
• Have the meter periodically checked against a reference standard, particularly if used where accuracy matters.

Frequently Asked Questions

What does “Precision” mean for this meter?

“Precision” is part of this product’s name rather than a stated accuracy figure. Please ask our sales team to confirm the accuracy class for this specific model.

What does “MR87” refer to?

MR87 identifies the meter’s model or case format, which is a different physical pattern from the MR66 format used on some of our other analog meters. Please confirm exact dimensions with our sales team.

What electrical quantity does it measure?

This is model-dependent. Our sales team can confirm the exact measured quantity and range before you order.

How is this different from the MR66 meters?

The MR87 uses a different case format from the MR66-format meters in our range. Our sales team can compare the specific dimensions and configurations against your requirements.

Does it need calibration?

Like other analog pointer instruments, accuracy can drift over time and with mechanical shock, so periodic checking against a reference standard is recommended, especially for precision-sensitive work.

Can it be panel-mounted into a trainer or switchboard?

It is designed to be mounted into a compatible panel or trainer chassis where the cutout size matches the MR87 housing. Please confirm mounting dimensions before purchase.
