Product Description
galvanometer, instrument for measuring a small electrical current or a function of the current by deflection of a moving coil. The deflection is a mechanical rotation derived from forces resulting from the current.Advanced Sensitivity for Accurate MeasurementsThe single scale on the Light Spot Galvanometer can resolve currents as low as 1 A, with an impressive resolution of 0.1 A. Designed for precision, this instrument is essential for meticulous current measurements in physics labs and educational research applications where high sensitivity is critical.
Durable and User-Friendly ConstructionBuilt with anodized aluminum housing and equipped with gold-plated binding terminals, this galvanometer ensures reliability and longevity. The external screw calibration provides convenient zero adjustment, while laser-etched scale printing facilitates clear and immediate readings during experiments.
Reliable Operation and Safety FeaturesIntended for indoor laboratory use, the Light Spot Galvanometer features an overload protection fuse and operates efficiently within temperatures from 0C to 40C. The suspended coil mechanism and low friction design offer rapid response times (1 second) and dependable measurements for scientific analysis.
FAQ's of light Spot Galvanometer:
Q: How does the Light Spot Galvanometer detect small electric currents?
A: The galvanometer operates on the principle of light beam deflection, using a suspended coil with torsion wire. When current passes through the coil, it rotates, moving a light spot across the 4 cm optical mirror scale for precise measurement of currents between 30 A and 3 mA.
Q: What benefits does the laser-etched mirror scale provide?
A: The laser-etched scale enhances visibility and accuracy, minimizing parallax errors and ensuring precise readings of minute current changes during laboratory measurements.
Q: When should external zero adjustment be used?
A: External zero adjustment, via the calibration screw, should be performed before measurements commence or whenever the instrument's baseline spot appears offset. This ensures the highest degree of accuracy during experiments.
Q: Where is the Light Spot Galvanometer ideally used?
A: This instrument is designed for use in controlled indoor laboratory environments, particularly physics labs in academic, research, or industrial settings where precision in detecting small currents is required.
Q: What is the recommended process for connecting the galvanometer?
A: Connections should be made using the gold-plated binding posts, ensuring secure and low-resistance contact with laboratory equipment. The device should be mounted securely on a bench or stand for stable readings.
Q: How does overload protection benefit the user?
A: An integrated fuse protects the galvanometer against excessive current, safeguarding the sensitive coil mechanism from damage and prolonging the life of the instrument.
