EC505 Desk Calculator

The Aurora EC505 desk EcoCalc, is made from
recycled plastic, powered entirely by light and is
totally battery free. It has a large 12 digit LCD
display for easy viewing, hard plastic keys and
large numerals for ease of use and Aurora’s
patented long equals bar to enable speedy
calculations. The handy Cost-Sell-Margin
function is great for sales and gross profit
calculations and the patented DirecKey feature
means that this calculator turns on when any key
is pressed, this key stroke will also register. So
overall a great calculator that combines
functionality with eco-friendly features.
