HP Scientific Calculator 33S

HP 33s Scientific Calculator
HP's ultimate scientific calculator—Pocket sized RPN
programmability for professional performance
Ideal for engineers, surveyors, college students,
scientists and medical professionals. Executing
scientific projects require speed accuracy, functionality
and dependability for success. The HP 33S scientific
programmable calculator is designed to deliver them
all, with features that include your choice of RPN* and
algebraic data-entry modes, 31KB user memory, a
powerful two-line display, and the timesaving HP Solve
application. In addition the HP 33S was built for the
mobile professional with a compact, lightweight design
and rubber side grips for increased comfort.
