Instruments that set their OWN standards —
• The Simpson record is one more proof that a higher standard does not have to wait long for recognition. Unknown before August 1936, Simpson equipment enters 1939 at the head of the instrument procession in the opinion of hundreds of servicemen who recognize the finer things in radio testing equipment.
See these modern instruments. Examine them critically. Measure them by any standard — design, workmanship, range, performance, beauty, and above all sheer quality in solid terms of dollar value. One careful inspection of any Simpson Instrument will be your final reason for standardizing on this versatile line for all of your testing needs.
A few of the many Simpson Instruments are briefly described here — instruments that can make 1939 a happy servicing year for you. Ask for latest bulletins.
