Scientific model with a fluorescent display; similar in styling to the TI-30. At first glance the European TI-45 is identical to the SR-40. Surprisingly the TI-45 features a green fluorescent display, a major exception in the Majestic-line.

Two variations of the TI-45 were reported, they differ in the mask over the display. The later model with a moulded TI-logo and TEXAS INSTRUMENTS nameplate. Our model is the earlier one.
