From the Manufacturer:
The 719 S Titrino is an economical yet versatile instrument of the Titrino series. Like all Titrinos it is noted for its compactness and its ease of operation by three buttons on the front plate or by the separate keypad. The methods ready for use that are stored in the instrument make start-up easy.
