The tt7000 is a modularly designed industry PDA. The tt7000 has an extremely broad range of application despite its protection class and impact resistance. Ergonomics and suitability for daily use: All of the tt7000’s interfaces are water resistant and dust-proof in accordance with IP 64. The radical reduction to one central and several optical interfaces makes the device extremely robust and stable. The laterally ribbed structure guarantees a high level of impact resistance and scratch resistance and simultaneously allows the use of a compact housing concept as well. The design and technical components are optimally matched with one another to fulfil the many demands placed on the tt7000 by the user. The PDA is thus suitable for various fields of application and can also be extended by adding diverse modular components.
