½ ACTUAL SIZE

PRE-SHRUNK FOR EASY PORTABILITY Now Hitachi has miniaturized the electronic recorder. The Model Q P D i 3 weighs only 10 kg. (22 lbs). It is actually only twice as large as the picture on this page. Even secretaries can pick it up and move it wherever it may be needed. Portability, however, is only part of the story. High Speed — Less than one second is re­ quired for the recording pen to travel over the full scale of 250 mm. Conventional recorders take 3 to 5 seconds. High Sensitivity — It can respond to rapid changes as well as changes of 0 . 1 % of the full scale. When the rated input voltage is DC 1 mV, the recorder can respond to 1 //V. Multi-speed — Three speeds can be selected even while the recorder is in operation. Circle ND. S on

Horizontal Feed — The chart is emitted hori­ zontally instead of vertically so that check marks can be easily inscribed. These arc only some of the features incor­ porated in Hitachi's new electronic self-balancing recorder. It has a wide range of applications in research and experimental requirements. It's an economic investment that pays immediate dividends. Model Q P D 3 3 is a product of Hitachi, manu­ facturer of more than 10,000 basic products for industry and the home. Look for the name and buy with confidence.
