The Eaton MTL GECMA IS Tablet PC is the only current Zone 1 tablet that runs Windows on an x86 processor, so Windows desktop software runs natively, with no emulation. It is intrinsically safe to Ex ia, IIC T4 for gas and IIIC T135°C for dust, certified for Zone 1/21 under ATEX and IECEx, and Zone 0 rated only inside the case supplied by Eaton. Its UL certification covers Class I Division 1, but only for Groups C and D at T4, so hydrogen and acetylene are outside its North American certificate.
It runs Windows 11 IoT Enterprise, with a 10.1-inch 2560 × 1600 screen, 8 GB of memory and 256 GB of storage. The 49.68 Wh battery, a typical 12 hours, is the largest of any current Zone 1 tablet, NFC is built in, a stylus is supplied, a camera-free version is offered, and a docking station is available for the safe area. It is rated from −20 °C to +55 °C, and Eaton’s manual shows IP67, which the IECEx certificate does not state.
Its processor is a quad-core Intel Atom (Apollo Lake) at 1.6 GHz (1.8 GHz burst), where the Getac, BARTEC and ecom picks use 12th or 13th-generation Intel Core or Core Ultra chips, and the 540-nit screen is the dimmest of the picks that state a figure. At 1,430 g it is the second heaviest of our five, after the Getac F110-EX G7 at 1,680 g, it is T4, the battery is not user-replaceable, and charging and connecting are for safe areas only. Eaton does not state which release of Windows 11 IoT Enterprise it ships, so ask for the edition and its support date before you plan a replacement cycle.
