Since 1910, the name "HICKOK" inscribed on elec- trical and electronic instruments has been the assur- ance of the finest and most dependable in electronic test equipment. For longer than there has been an "electronics" industry, HICKOK engineering has continually pioneered in the development of highest quality, versatile, reliable test and indicating instruments.

From the days of Marconi's wireless, into the age of semiconductors, HICKOK has led the way in such 1910-1964 important development as: HICKOK • The first Dynamic Mutual Conductance Tube Tester , universally accepted as providing the standard test Recognized For Excellence of a vacuum tube .. . HICKOK tube testers have been widely emulated -they have never been surpassed.

For 54 Years • The friction·free, Taut-Band Meter-eliminating friction from pivots, jewels and hairsprings.

• 250 0 Scale Meters .

• Sub-miniature, ruggedized meters built to military specifications.

• And now, in the Transistor Age-a full line of tran· sistor testing instruments featuring the same ease of operation, unmatched versatility, une xcelled reliability that have characterized HICKOK products for more than half a century. ,1~ ];~-'[ gu;4-eo ~,~zc.

It is id eal for quality control , incoming inspection and sorting and other assi gnme nts requiring precise measurement of transistor performance. To provide fast, accurate set-ups , vital to effi cient volume testing , the instrument has a speed -engineered control layout. All AC beta test controls are on the left side of the panel; DC beta test controls on the right. Common contro ls are placed under the meter, above the handy roll chart containing set-up information for more than 2500 transistors. The Model 870 can also be set up by using handbook information -making it indispensable for c ust om tests to individual performance requirements in specific applications .
