Scientific Calculator Brown Bezel k7

It is a good choice for people who want a calculator that is small enough to slip into a pocket or backpack but also has a bright LCD display for easy reading whenever and wherever it is used. This HP calculator is mid-sized at 3.1' x 5.8' x 0.6' and uses a small built-in solar panel to keep its three LR44 batteries fully charged from any light source. It comes with over 100 built-in math, science and trigonometry functions and supports RPN data entry. The basic unit has a 384 bit memory and the keyboard contains 26 variable keys for all complex calculations. This HP calculator can perform time conversions that include decimals, hours, minutes and seconds, angle and polar conversions, unit conversions and it can complete basic arithmetic processes in its 12-digit display. Using a solar-powered calculator means never having to remember to charge the device before use or not having to worry about an unusable HP 32sII at a critical moment.
