Classroom 24-pack scientific calculators

This 24-pack of Mr. Pen scientific calculators supplies a full classroom, study group or office with identical units so every user works from the same feature set. Each calculator handles trigonometric, statistical and algebraic operations required by secondary and introductory college curricula. The bulk quantity eliminates the need to mix models or share devices during exams.

Dual solar and battery power

Solar cells provide primary power in normal indoor or outdoor light while a battery backup takes over automatically in dim conditions. The two-source design removes the downtime that occurs when a single-power calculator loses charge mid-lesson. No external charger or cable is required to keep the fleet running.

10+2 digit display with protective case

A 10+2 digit screen shows mantissa and exponent together, letting students verify long entries without scrolling. Every unit includes a removable hard cover that shields the keyboard and display from desk scratches and bag compression. The case adds no bulk that would prevent stacking in a storage tray.

Questions about this item

What size protective case fits each calculator in the 24-pack?

Each unit ships with its own removable hard-shell case that snaps over the 10+2 digit body; no extra sizing is needed.

How do I install the battery backup on a new unit?

Peel the protective film from the solar strip, then pull the plastic tab from the pre-installed button cell; the calculator powers on automatically.

What part will need replacement first on these solar-and-battery calculators?

The internal button cell will eventually run down; when the display fades in dim light, swap in a fresh cell of the same type.
