The SDI Animal Stimulator can be used for conditioning prior to testing. Use the Animal Stimulator wherever pairing of light and shock and/or sound and shock are required. There are three stimuli: light, sound and shock. In addition, there is an auxiliary connection that allows you to connect your own device. The LED light unit provides very bright light with no heat. The sound is controlled by the computer sound card allowing flexibility in sound selection and amplitude. The shocker is a solid state unit providing constant current shock to the grid in a random pattern via eight outputs.
