OVERVIEW

Ideal for engineers, surveyors, college students, scientists and medical professionals.

Accuracy, functionality, dependability.

Scientific projects require these vital attributes for success.

The pocket-sized HP33S scientific programmable calculator delivers them - and more - with features that include 31KB user memory, your choice of RPN and algebraic data-entry modes, a powerful two-line display, and the timesaving HP Solve application.

 Permitted for use on SAT I, SAT II Math IC/IIC, ACT, PSAT/NMSQT, AP Chemistry/Physics, PLAN, EXPLORE.
