The Tab-Ex 05 DZ2 takes first place because it carries the widest set of Zone 2 certificates of any tablet we rank. Its Ex ic IIC T5 Gc rating for gas and Ex ic IIIC T85 °C Dc for dust puts it at T5, a 100 °C limit, where every other current Zone 2 tablet with a North American Division listing in our data is T4, and it covers conductive dust. ATEX (a Bureau Veritas certificate of conformity, which category 3 equipment does not strictly need) and IECEx are both held, and the SGS North American certificate lists Class I and II Division 2, Class III Division 1 and 2 and Zone 2 IIC T5. National approvals add Brazil, Korea and South Africa.
It is a capable 8-inch Android tablet too: IP68 and MIL-STD-810H, glove and wet-hand touch, an included S Pen, a 600-nit screen, an Exynos 1380 with 6 GB, NFC, 5G and a programmable function key for push-to-talk, emergency calls or alarms. A camera-free version suits sites that restrict cameras. ecom quotes up to 14 hours of battery life and states security updates to 2032 (Q1 2032 in our data, a maker’s statement).
Read the North American conditions: under the NEC and CEC listing the ambient limit is +50 °C and the dust group is IIIB, not the +55 °C and IIIC of the ATEX and IECEx certificates. The weight of 595 g is from a single source and ecom’s own figures vary, the protective case must be fitted before entering a hazardous area, and wired connections (USB-C and POGO pins) and charging are for ordinary areas only.
