TI-36eco_RS_1.jpg (20556 Byte)This calculator is identical to the TI-36X Solar introduced in the year 1996.

The main difference is the marketing concept. 

The housing is made of recycled plastics and together with the solar cells instead of batteries this allowed Texas Instruments Germany to use the "
Umweltzeichen" sign.

Consumers in Germany call it the "Blue Angel". Its official name is "Umweltzeichen" (Environmental Label or the "Eco-Mark"). What they are referring to is a special logo, which has for two decades now been a symbol for products with positive environmental features on the German market. Well over 4,000 products now bear the mark. This success is proof of the increased environmental awareness both of producers and of consumers. Because the Environmental label is an entirely voluntary labelling of a productís environmentally friendly features.

Don't miss the TI-30 eco RS calculator introduced in the same year.

Texas Instruments introduced in May 2004 without any announcement the completely redesigned TI-36X SOLAR and gave a first outlook to the impressive design of the BA II PLUS Professional
