Tektronix Model 221 Oscilloscope
The 200 series mini-scopes are ideal for industrial maintenance applications where portability is a must. The 221 is lightweight, compact and built of impact resistant, double insulated plastic. Since they are double insulated they allow you to make floating measurements and can be elevated to 600 V (dc + peak ac) above ground when operated from batteries.
