Desktop calculator SENCOR SEC 150 BU — solar-powered compact, two-line LCD, 12+10+2 digits, 240 functions

SENCOR SEC 150 BU is a compact, solar-powered scientific calculator designed for school and general-purpose use. It features a large two-line LCD display with a dot-matrix line and a 7-segment line, supports up to 12 and 10+2 digits respectively, and includes 240 scientific functions for a wide range of calculations. The unit is lightweight, measures 80×150×15 mm and comes with a protective slide cover and a two-color case option.

Advantages

The calculator offers comprehensive functionality including fraction calculations, trigonometric and hyperbolic functions, logarithmic and exponential operations, coordinate and degree conversions, as well as square and square root computations. It also supports statistical calculations such as regression and variation, combination calculations, and number-system conversions (binary, octal, hexadecimal). Dual power (solar) operation and automatic power-off extend battery life while parenthesis handling and independent memories simplify multi-step problems.

Suitable for

• School mathematics and science classes
• Homework and study sessions
• Basic statistical and regression analysis
• Engineering and programming tasks requiring hexadecimal or binary conversions
• Everyday budgeting and quick desktop calculations

How to use

Place the calculator in a well-lit area so the solar panel can supply power. Use the two-line display to enter complex expressions: the dot-matrix line shows formulas while the 7-segment line displays numeric results. Apply parentheses and independent memories to break down multi-step problems, select the desired math mode for trigonometric or statistical operations, and switch between number-system modes for conversions. The protective slide cover should be used when transporting the device to prevent key or display damage.

Usage recommendations

For classroom and study work, verify calculator mode settings (angle units, number-system mode) before starting calculations. Keep the solar panel clean and avoid prolonged storage in dark places to maintain reliable operation.
