If the battery is what ends your shift, the tablet that can be charged where it is used wins the argument. The i.safe MOBILE IS940.1 may be charged inside the hazardous area, and its IECEx certificate also covers the IS-DS940.1 docking station (VESA 100) that i.safe lists for charging there, so a crew can dock it at the work area between tasks instead of walking out to a charging point. That makes it one of only two current Zone 1 tablets that may be charged in the zone, and it has the Android model’s confirmed update date, a user-replaceable 8,160 mAh battery and IP68. A docked operator-panel version, the IS-MOP1A.1 (which needs a separate Ex enclosure for its connectivity module), is also offered for fixed positions.
It is intrinsically safe to Ex ib IIC T4 for Zone 1/21 with dust group IIIC under ATEX and IECEx, with a Class I Division 1 listing for North America. It is a 10.1-inch Android 14 tablet with 5G and Wi-Fi 6, and security updates until Q4 2032.
The limits are the certificate’s conditions, and they matter for long shifts. Charging is limited to a temperature of 0 °C to +45 °C, the USB-C interface under its IP cover may only be opened outside hazardous areas (so in-zone charging is on the dock, not by USB-C cable), the 16-pin ISM interface must stay covered, and the battery may be replaced outside the hazardous area only. Our data has no battery-life figure for it, and its 30.2 Wh capacity is calculated from the maker’s capacity and voltage, so ask i.safe for a runtime trial. It is T4, not certified for Zone 0, and weighs 1,059 g.
