<br />This is two of the best recorders ever built�
<br />•
<br />That's right — two completely inde-
<br />p�ndent measuring and recording sys-
<br />tems in one compact Speedomax W
<br />case, sharing the same wide chart.
<br />Lets you compare or contrast two re-
<br />(ated variables, using the same or dif-
<br />: ferent types of prim�ry elements — for
<br />Stress and strain, width and thickness,
<br />kw and kvar, temperature and tempec.:-
<br />ture difference, etc.—with an instrument
<br />performance never before available.
<br />For this new Speedomax W Two-Pen
<br />Recorder embodies advanced design
<br />concepts, both r;e-ctrical and mechan-
<br />ical.
<br />0 Shielded circuitry and input filtering
<br />to provide noise �ejection.
<br />❑ Twin solid-state ampiifiers, for opti-
<br />mum dependability.
<br />❑ Unitized modular servo systems pro-
<br />vide maximum flexibility v✓ith com-
<br />plete accessibility to all components
<br />and subassemblies.
<br />❑ Independent pens traveling the full
<br />10-inch chart span, capillary-su�plied
<br />from massive ir�k reservoirs ... re-
<br />plac�able in seconds.
<br />❑ A new chart-drive assembly that
<br />makes chart replacement a snap.
<br />❑ Optional switch-seleciion from up to
<br />5 chart spe�ds, ranging from one inch
<br />per hour to 30 inches per minute.
<br />Need more than just a record? No
<br />problem. You can have signaling or con-
<br />trol—ranging from simple or�-off to full
<br />proportioning—for eit�er or both var-
<br />iables.
<br />These ire only a few of the exciting
<br />features of this ne�v recorder—a part of
<br />our redoubled effort to give you the
<br />finest in recording and control.
<br />But there's one thing that hasn't
<br />doubled.
<br />The price.

<br />L&N office, or write �us at 4901 Stenton
<br />.'�venue, Philadelphia, Pa. 19144.
