ecom Tab-Ex 05 DZ1 vs i.safe MOBILE IS930.1
These two 8-inch Android tablets are certified for Zone 1/21 under ATEX and IECEx, both with a Class I Division 1 listing for North America, so on where they may be used they start level. The ecom Tab-Ex 05 DZ1, which replaced the discontinued ecom Tab-Ex 03 DZ1, is flameproof (Ex db) with an intrinsically safe circuit and rated T6. The i.safe MOBILE IS930.1 is intrinsically safe (Ex ib), rated T4, and 232 g lighter, but i.safe’s security updates for it end in Q1 2027. Here is how they compare, and which we would choose for which team.

Our verdict
Which should you choose?
Both tablets cover Zone 1/21, so pick by your gases, your sites and how long the tablets must stay in service. For sites with gases that ignite at lower temperatures, a fleet bought to last several years, and scanning with a certified accessory, we would choose the ecom Tab-Ex 05 DZ1. For crews who carry the tablet all shift, hot sites up to +60 °C, underground work and short projects or existing fleets, we would choose the i.safe MOBILE IS930.1.
Choose the ecom Tab-Ex 05 DZ1 if…
- Your hazardous-area study includes gases that ignite below 135 °C: it is rated T6 (85 °C) and T80 °C for dust, against T4 and 135 °C for the i.safe MOBILE IS930.1.
- You are buying a fleet for years of service: i.safe’s security updates for the i.safe MOBILE IS930.1 end in Q1 2027, while ecom states updates until 2032 for this tablet (a date our data flags as unconfirmed).
- Your team scans labels and tags in Zone 1/21: ecom’s Ident-Ex 02 wireless 1D/2D scanner has its own Ex approval, while our data lists only camera-based scanning by app, with no dedicated scan engine, for the i.safe MOBILE IS930.1.
- You need a wired data connection in the hazardous area: its USB-C port may be used for data there within its entity parameters, where the i.safe MOBILE IS930.1 allows no cover to be opened.
- You want faster connectivity and more memory: it has 5G, Wi-Fi 6 and 6 GB of RAM, against 4G LTE, Wi-Fi 5 and 4 GB.
Choose the i.safe MOBILE IS930.1 if…
- Crews carry the tablet through a whole shift: it weighs 890 g, against 1,122 g for the ecom Tab-Ex 05 DZ1.
- Your sites run hot: it is certified up to +60 °C ambient, against +55 °C for the ecom Tab-Ex 05 DZ1.
- You want a dedicated alarm control: it has a red SOS key, plus two freely programmable keys.
- Some of your crews work underground: the i.safe MOBILE IS930.M1 mining version adds Group I certification.
- A client or site asks for UKCA-marked equipment: it has a UKEX certificate as well as ATEX and IECEx, and our data lists none for the ecom Tab-Ex 05 DZ1.
Key differences
Where they differ
Temperature class
- ecom Tab-Ex 05 DZ1
- T6 (≤ 85 °C)
- i.safe MOBILE IS930.1
- T4 (≤ 135 °C)
The temperature class decides which gases a tablet may be used around. T6 (85 °C) is the stricter rating; T4 (135 °C) is fine for most gases, but not those that ignite below 135 °C. Check your site’s gases against it before anything else.
Security updates
- ecom Tab-Ex 05 DZ1
- Until Q1 2032Unconfirmed, see note 1
- i.safe MOBILE IS930.1
- Until Q1 2027
i.safe’s updates for the i.safe MOBILE IS930.1 end in Q1 2027, which matters for anyone buying now. ecom states updates until 2032 for the ecom Tab-Ex 05 DZ1, a date our data flags as unconfirmed.
Weight
- ecom Tab-Ex 05 DZ1
- 1122 g
- i.safe MOBILE IS930.1
- 890 g
The i.safe MOBILE IS930.1 is 232 g lighter, which you notice when a tablet is carried on a strap or held in one hand through a shift. The ecom Tab-Ex 05 DZ1 is the heavier tablet at 1,122 g.
Barcode scanning
- ecom Tab-Ex 05 DZ1
- Via accessory (ecom Ident-Ex 02 wireless 1D/2D scanner; Ex-rated? yes) or camera-based via app
- i.safe MOBILE IS930.1
- Via app (camera-based; no dedicated scan engine listed)
The ecom Tab-Ex 05 DZ1 works with ecom’s Ident-Ex 02 wireless 1D/2D scanner, which carries its own Ex approval for Zone 1/21 and Division 1. For the i.safe MOBILE IS930.1, our data lists camera-based scanning by app and no dedicated scan engine. For teams that scan through the shift, this can decide the choice.
In the field
Head to head, by kind of work
Gas coverage and temperature class
Edge: ecom Tab-Ex 05 DZ1
On many sites this point decides the purchase. Both tablets are certified for gas group IIC and dust group IIIC, but the ecom Tab-Ex 05 DZ1 is rated T6, with a maximum surface temperature of 85 °C for gas and 80 °C for dust. The i.safe MOBILE IS930.1 is rated T4, with 135 °C for both. T4 is fine for most gases, but not those that ignite below 135 °C. If your hazardous-area study lists none, the gap will not matter to you.
The North American listings follow the same split. Both cover Class I Division 1 Groups A, B, C and D and Class II Division 1 Groups E, F and G. ecom’s SGS certificate for the ecom Tab-Ex 05 DZ1 is at T6 and T80 °C, and the i.safe MOBILE IS930.1’s NEC 500 listing is at T4 and T135 °C. For a team that works on sites with a low-ignition-temperature gas, the lower codes give ecom the wider margin.
Weight, screen and keys
Even
The i.safe MOBILE IS930.1 weighs 890 g against 1,122 g for the ecom Tab-Ex 05 DZ1, a gap of 232 g that shows over a shift on the move. Both have an 8-inch display, glove touch, a 13 MP rear camera and NFC. Our data describes the ecom Tab-Ex 05 DZ1’s screen in more detail: 1920 × 1200, up to 600 nits, wet-hands operation and an S Pen included. It has no resolution, brightness or pen entry for the i.safe MOBILE IS930.1, which means unverified, not absent.
On keys, the i.safe MOBILE IS930.1 has a dedicated red SOS key and two programmable keys, with push-to-talk through an app. The ecom Tab-Ex 05 DZ1 has a programmable function key that can be set to push-to-talk, an emergency call or an alarm. For scanning, ecom’s Ident-Ex 02 wireless 1D/2D scanner carries its own Ex approval, while the i.safe MOBILE IS930.1 scans through a camera app and lists no dedicated scan engine.
Updates, connectivity and battery
Edge: ecom Tab-Ex 05 DZ1
Support life comes first. i.safe’s security updates for the i.safe MOBILE IS930.1, a tablet that runs Android 14, end in Q1 2027. ecom states security updates until 2032 for the ecom Tab-Ex 05 DZ1, which is Android Enterprise Recommended; our data flags that date as unconfirmed, so the edge here rests on the confirmed points: the Q1 2027 end and the hardware below. A short project or an existing i.safe MOBILE fleet can live with Q1 2027, but a new multi-year rollout cannot.
The hardware follows the same pattern. The ecom Tab-Ex 05 DZ1 has an Exynos 1380 with 6 GB of RAM, 128 GB of storage, 5G and Wi-Fi 6. The i.safe MOBILE IS930.1 has a Snapdragon SDM660 with 4 GB, 64 GB, 4G LTE (no 5G) and Wi-Fi 5. Neither battery is user-replaceable and both charge outside the hazardous area only. ecom quotes up to 14 hours of battery life; our data has no figure for i.safe, so we do not compare runtime.
Certification, heat and mining work
Edge: i.safe MOBILE IS930.1
The i.safe MOBILE IS930.1 has the broader certification spread. It holds ATEX, IECEx and UKEX certificates, where our data lists no UKEX certificate for the ecom Tab-Ex 05 DZ1, and it is certified to +60 °C ambient against +55 °C. Its ports are stricter in the zone: no interface cover may be opened there, though a commercial microSD card may be used in its slot. The ecom Tab-Ex 05 DZ1’s SIM and microSD slots are likewise reachable only in non-hazardous areas, but its USB-C port may carry wired data in the zone.
For underground work, i.safe offers the i.safe MOBILE IS930.M1, certified for Group I with the marking I M1 Ex ia I Ma. Our data lists no mining version of the ecom Tab-Ex 05 DZ1, so treat it as a surface tablet unless ecom confirms otherwise. The i.safe MOBILE IS930.M1 marking includes IP64, while i.safe lists the standard model as IP68, so check the mining version’s ingress rating with i.safe before ordering.

FAQ
Common questions
Is the ecom Tab-Ex 05 DZ1 better than the i.safe MOBILE IS930.1?
Neither is better across the board. The ecom Tab-Ex 05 DZ1 suits sites with gases that need T6, fleets meant to last for years, and teams that scan with a certified accessory. The i.safe MOBILE IS930.1 suits crews who want the lighter tablet, hot sites up to +60 °C, and operators who also work underground. Both are certified for Zone 1/21 and Class I Division 1.
Can either tablet be used in Zone 0?
No. Both are certified to protection level Gb, which covers Zone 1 and Zone 2, and neither is certified for Zone 0. The ecom Tab-Ex 05 DZ1 is flameproof (Ex db) with an intrinsically safe circuit (Ex ia), and the i.safe MOBILE IS930.1 is intrinsically safe (Ex ib).
Are both tablets approved for North America?
Yes. Both are listed for Class I Division 1 Groups A, B, C and D and Class II Division 1 Groups E, F and G. The ecom Tab-Ex 05 DZ1 is listed at T6 on an SGS certificate, and the i.safe MOBILE IS930.1 at T4 under NEC 500.
Which gets security updates for longer?
The ecom Tab-Ex 05 DZ1, on the makers’ own dates. ecom states security updates until 2032, a date our data flags as unconfirmed, and i.safe lists Q1 2027 for the i.safe MOBILE IS930.1. If you are buying now, that shorter window is the main thing to plan around.
Can you charge either tablet in the hazardous area?
No. Both must be charged outside the hazardous area, and neither battery is user-replaceable. ecom specifies charging at −5 °C to +55 °C for the ecom Tab-Ex 05 DZ1, and i.safe specifies +5 °C to +35 °C for the i.safe MOBILE IS930.1.
