Product Overview

AL-E501A SPOT GALVANOMETER


Discription:

SCOPE OF LEARNING:

  • Spot Galvanometer finds extensive use as a D.C. null detector in wheat stone bridges and potentiometers
  • TECHNICAL SPECIFICATIONS:
    • MAINS: It is a' mains' operated instrument but can operate on a 6 volt battery also. There is provision to operate this instrument can be operated on both as well as main supply 220 volts, 50Hz or 6 Volt Capacity.
    • Light Source: The light Source is 6 Volt and 0.3Amp bulb giving a bright spot on the scale. 
    • Construction: The galvanometer has built in lamp and scale arrangement and housed in a Bakelite case. The highly sensitive moving coil system is suspended in a taut band manner in a uniform field of permanent magnet.
    • Scale: The scales are 150mm long and end zero use. 
    • Zero Adjustment: The spot of light can be set at any point on the scale with the help of zero adjusting knobs.
    • Sensitivity Control: The sensitivity is controlled by a 2-pole, 6 way switch. The switch Positions are D,1/10,1/100,1/1000 and s/c 
    • Working Voltage  :  220VAC 
    • Time Period        :  2 seconds
