Aurora EC404

EC404 Semi-Desk Calculator

The Aurora EC404 semi-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
