Contact SupplierGalvanometer edspot : a highly sensitive apparatus for measuring very small charges (of the order of µc) and currents (of the order of µa) and as null point detector. It has an integral taut suspension movement, lamp unit and scale, the indication being presented as a hairline in a brilliant light spot on a translucent screen. . Provision for effectively damping any transverse suspension vibrations, without affecting the electrical characteristics of the instrument. Signal input through 4mm colour coded socket terminals, with input circuit protected against accidental inputs of high magnitude. The front scale graduated in millimeters from 0-18cm (left zero) and 9-0-9cm (center zero), for reading as required. With lockunlock, zero adjustment and sensitivity adjustment at the front. Range attenuation - sensitivities of x 1x0.1, x0.01 and x 0.001, related to both current and voltage sensitivities with constant input resistance. Operates on 220-240c ac mains, 5060hz.
Time period : 2 second approx.
Resistance : 100 ohms
sensitivity : 15mmua
input main : 220v ac
dimensions : 295mmx210x130mm approx.
