Clinical Electrotherapy - Dynatron Solaris Plus Shrouded Lead Wire, 72" : The Dynatron Solaris Plus Shrouded Lead Wire is a 72-inch lead wire that is compatible with the Dynatron Solaris Plus. This wire is a direct replacement for the ones included with the original purchase of a Dynatronics Solaris Plus unit. It is advised that lead wires be replaced every six months because of the high voltage transmitted across them. Replace lead wires if your unit is "shocking" patients (spikes in output), the unit is terminating mid-treatment, or if there is no output. This shrouded lead wire is sold individually.
