Laboratory Galvanometer

A laboratory galvanometer for small-current detection in physics practicals. The existing listing describes an analog, centre-zero moving-coil instrument for indicating current direction and supporting null-point observations in bridge and potentiometer experiments.

Before setting up your practical, check the supplied instrument's scale and ratings against your circuit requirements.

Listed product details

• Instrument: galvanometer.
• Display: centre-zero analog scale, as described in the listing.
• Mechanism: moving-coil, described as D'Arsonval.
• Current type: DC, according to the existing specifications.
• Intended setting: school, college and university physics practicals.

Measurement specifications

The earlier description mentions microampere to milliampere sensitivity without supplying an exact range or sensitivity value. Confirm full-scale current, sensitivity, internal resistance, scale divisions and accuracy specifications before ordering.

No selectable model or range options are currently listed. Terminal type, dimensions, manufacturer and calibration documentation are not confirmed for the supplied model.

Use and care

Follow the manufacturer's circuit-connection instructions and use suitable current-limiting protection. Do not connect the galvanometer directly across a power source or exceed its rated input.

Maximum voltage and electrical safety category are not supplied. Do not assume suitability for mains or high-energy circuits. Leads and other accessories are not documented as included.
