White Light Spot Galvanometer

We are an authorized firm for trading and supplying of Light Spot Galvanometers from Chennai, Tamil Nadu, India. 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 (0i? .14 & 7i? .0i? .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.
