We stock most types of Texas Instruments calculators, including Graphing, Scientific, Financial and general purpose models.

Before any of our Texas Instruments calculators leave our facility, we perform our 3 step  ICU  process:

Inspect:  This process involves verifying there are no  visable signs of damage or wear and tear on the calculator.  Any product found with names engraved, screen burn or any other imperfections will be discarded before any further testing is completed. 
Clean:  All calculators are then tested for basic functionality.  Calculators that pass the functionality test are then cleaned.  Calculator,  front covers, and battery covers, are all cleaned with rubbing alcohol to remove any dust and or debris.  Rubbing alcohol is used because of its fast drying properties and to avoid the adverse effects caused by prolonged moisture to electronic sensative devices and decorative plastic coverings.

Upgrade:  Any calculator which has been inspected and cleaned will then be verified to see if it needs to have a software upgrade.  Upgrades are only performed on calculators after they have been inspected, found to be in working order with no visible signs of wear, and after they have been cleaned.  If software upgrades are needed, they are done through the TI website via the Texas Instruments TI connect software which is downloaded on our upgrade computers which are used for the upgrade process.
