Electro Convulsometer: 

The instrument provides 50Hz stimulus current which can be adjusted 0.15mA to 330mA in discrete steps for producing minimal and supra maximal seizures required in the assaying of anti-epileptic and anticonvulsant drugs. The application of stimulus current can be controlled by an electronic timer from 0.1 second to 1 second in steps of 0.1 to 3 seconds in 11 steps. An L.E.D. indicates the duration of stimulus.
