FAQ
Common questions
Is the ecom Tab-Ex 03 DZ1 certified for Zone 1?
Yes. The ecom Tab-Ex 03 DZ1 is certified for Zone 1/21 with the marking II 2G Ex db ia IIC T6 Gb IP64. Equipment certified for Zone 1 can also be used in Zone 2.
Can the ecom Tab-Ex 03 DZ1 be used in Zone 0?
No. It is not certified for Zone 0. Zone 0 needs equipment with protection level Ga, such as Ex ia intrinsic safety.
What type of explosion protection does the ecom Tab-Ex 03 DZ1 use?
It uses a flameproof enclosure (Ex db), a form of explosion-proof protection. The housing is built to contain an ignition inside it and stop the flame reaching the surrounding atmosphere.
What does T6 mean for the ecom Tab-Ex 03 DZ1?
Its surface stays below 85 °C, so it is suitable for gases that only ignite above that temperature. Check the ignition temperature of the substances on your site.
Can you charge the ecom Tab-Ex 03 DZ1 in a hazardous area?
No. The certificate only allows charging outside the hazardous area.
Which ports and accessories can be used with the ecom Tab-Ex 03 DZ1 in the hazardous area?
SIM and microSD are reachable only in non-hazardous areas (flameproof cover). The USB-C port is intrinsically safe and may be used for wired data connections in the hazardous area within its entity parameters (Uo 5.6 V, Io 500 mA, Po 600 mW, Co 1 µF, Lo 1 µH); charging via USB-C only in non-hazardous areas. The S Pen is intrinsically safe and may be used in the hazardous area.
What operating system does the ecom Tab-Ex 03 DZ1 run?
Android 13. Security updates ended in Q3 2025.
Is the ecom Tab-Ex 03 DZ1 still available?
No. ecom lists it as discontinued. Security patches ended in Q3 2025; hardware service runs to Q4 2027.
How much does the ecom Tab-Ex 03 DZ1 cost?
