Ammeter

We are leaders in the market for providing best range of Light Spot Galvanometer

Light Spot Galvanometer

Description

The instrument consists of a taut suspension movement, light source, projection system, scale and sensitivity control switch. All components of the instrument are housed in a dust free aluminium cabinet nicely finished by stoving enamel paint.

The light source consisting of a 4V 4W lamp is mounted on a small rectangular detachable plate fixed in front of the galvanometer housing to allow the bulb to be replaced. A circular plate is fixed on this rectangular plate which enables the exact adjustment of light spot. The Galvanometer indicator consists of a bright circular spot of light with a vertical hair line shadow on a translucent scale with dual graduations in millimeters (0.14 & 7.0.7 cms).

Two models are available for different purposes:

  • Voltage sensitive model Cat. No. PL64- In this model the coil resistance is low and it is useful for measurement of low resistances.
  • Current sensitive model Cat No PL64.01- In this model the coil resistance is high and it is useful where high resistances are measured.
  • FEATURES
  • High sensitivity (70 mm/ A)
  • Five sensitivity positions
  • Built-in universal shunt
  • Constant terminal resistance
