i.safe MOBILE IS930.1 vs i.safe MOBILE IS940.1
These two Android tablets from the same maker share their certification: intrinsically safe (Ex ib), IIC T4, Zone 1/21 under ATEX and IECEx, and a Class I Division 1 listing for Groups A to D. The choice is size and support life. The i.safe MOBILE IS930.1 is an 8-inch, 890 g tablet whose security updates end in Q1 2027. The i.safe MOBILE IS940.1 is a 10.1-inch, 1,059 g tablet with 5G, security updates until Q4 2032, and i.safe allows it to be charged inside the hazardous area. Here is how they compare, and which we would choose for which team.

Our verdict
Which should you choose?
For a new fleet we would choose the i.safe MOBILE IS940.1: its updates run to Q4 2032, against Q1 2027 for the i.safe MOBILE IS930.1, it has the larger screen and 5G, and it may be charged in the zone. We would choose the i.safe MOBILE IS930.1 for short projects that end before Q1 2027, for crews who want the lighter 8-inch tablet, for sites that run hotter than +55 °C, and where a UKEX certificate is required.
Choose the i.safe MOBILE IS930.1 if…
- Your project or contract ends before Q1 2027, when i.safe’s security updates for the i.safe MOBILE IS930.1 end.
- Crews carry the tablet through a whole shift: it weighs 890 g against 1,059 g for the i.safe MOBILE IS940.1, a gap of 169 g.
- Your sites run hot: it is certified up to +60 °C ambient, against +55 °C for the i.safe MOBILE IS940.1.

Screen size
- i.safe MOBILE IS930.1
- 8-inch Glove-usable touch display; Corning Gorilla Glass V3 stated on the IS930.M1 page (not on the IS930.1 page)
- i.safe MOBILE IS940.1
- 10.1-inch Corning Gorilla Glass V3 (3rd generation), usable with gloves
The i.safe MOBILE IS940.1 has a 10.1-inch screen and the i.safe MOBILE IS930.1 an 8-inch one. The larger screen suits drawings and forms. The i.safe MOBILE IS930.1 is the smaller, lighter tablet.

In the field
Head to head, by kind of work
Support life, performance and connectivity
Edge: i.safe MOBILE IS940.1
Support life comes first. i.safe’s security updates for the i.safe MOBILE IS930.1 end in Q1 2027. That tablet shipped with Android 9 and now runs Android 14. For the i.safe MOBILE IS940.1, which runs Android 14 too, i.safe states security updates until Q4 2032. A short project or an existing i.safe MOBILE IS930.1 fleet can live with Q1 2027, but a new multi-year rollout cannot.
The hardware follows the same pattern. The i.safe MOBILE IS940.1 has a Qualcomm QCM6490, a long-term support chipset, with 8 GB of RAM, 128 GB of storage, 5G NR, Wi-Fi 6, Bluetooth 5.2 and dual SIM (nano-SIM and eSIM). The i.safe MOBILE IS930.1 has a Snapdragon SDM660 with 4 GB, 64 GB (microSD up to 512 GB), 4G LTE with no 5G, Wi-Fi 5, Bluetooth 5 and a micro-SIM. Both have NFC.
Screen, camera and weight
Even
The i.safe MOBILE IS930.1 weighs 890 g and has an 8-inch glove-usable touch display. The i.safe MOBILE IS940.1 weighs 1,059 g and has a 10.1-inch Gorilla Glass V3 display at 1200 × 1920, also usable with gloves. Our data has no resolution for the i.safe MOBILE IS930.1, which means unverified, not absent. Both tablets are IP68 and list MIL-STD-810H. The choice is carrying comfort against reading space, and only your crews can settle it.
On cameras, the i.safe MOBILE IS940.1 has a 50 MP autofocus rear camera and the i.safe MOBILE IS930.1 a 13 MP autofocus one, and both have a 5 MP fixed-focus front camera. Neither lists a dedicated scan engine, so both scan by camera through an app. On keys, the i.safe MOBILE IS930.1 has a dedicated red SOS key and two programmable keys, and the i.safe MOBILE IS940.1 a freely programmable red key, for example for SOS or a lone-worker app, plus programmable side buttons.
Charging, battery and accessories in the zone
Edge: i.safe MOBILE IS940.1
The i.safe MOBILE IS940.1 may be charged inside the hazardous area, within the certificate’s limits, and i.safe lists the IS-DS940.1 docking station for charging in the Ex area. Its battery is user-replaceable, changed outside the hazardous area only. The i.safe MOBILE IS930.1’s battery is not user-replaceable, and it must be charged outside the hazardous area, with its IS-DS930.1 docking station and charging cables for safe areas only. Our data has no battery-life figure for either, so we do not compare runtime.
Ports differ in the zone too. On the i.safe MOBILE IS930.1, no interface or connector cover may be opened in an Ex area, though a commercial microSD card may be used in its slot. On the i.safe MOBILE IS940.1 the USB-C cover stays closed, but its 16-pin interface takes the Ex-rated IS-HS2A.1 headset, the IS-RSM3A.1 remote speaker microphone and the IS-PTTB1A.1 push-to-talk button. Our data does not state which accessories are Ex-rated for the i.safe MOBILE IS930.1.
Certificates, heat and mining work
Edge: i.safe MOBILE IS930.1
The i.safe MOBILE IS930.1 has the broader certificate list. It holds ATEX, IECEx and UKEX certificates (CML 21UKEX2490X), where our data lists no UKEX certificate for the i.safe MOBILE IS940.1, and it is certified to +60 °C ambient against +55 °C. Its other approvals include EAC and TELEC, and the i.safe MOBILE IS940.1’s include PCEC (China). Both list IA (South Africa), INMETRO, Japan-Ex, PESO and KCs. Both are listed for Class I Division 1 Groups A to D at T4, Class II Division 1 Groups E, F and G, and Class III.
For underground work, i.safe offers a mining version of each: the i.safe MOBILE IS930.M1 and the i.safe MOBILE IS940.M1, both certified for Group I. The i.safe MOBILE IS930.M1 marking includes IP64, while i.safe lists the standard i.safe MOBILE IS930.1 as IP68, so check the mining version’s ingress rating with i.safe before ordering. For fixed positions, i.safe also offers the i.safe MOBILE IS940.1 as the IS-MOP1A.1 operator panel, which needs a separate Ex enclosure for its connectivity module.

FAQ
Common questions
Is the i.safe MOBILE IS930.1 better than the i.safe MOBILE IS940.1?
Neither is better across the board, but for a new fleet we would choose the i.safe MOBILE IS940.1, because the i.safe MOBILE IS930.1’s security updates end in Q1 2027. The i.safe MOBILE IS930.1 suits short projects, crews who want a lighter 8-inch tablet and hot sites up to +60 °C. Both are certified for Zone 1/21 and Class I Division 1.
Can either tablet be used in Zone 0?
No. Both are intrinsically safe (Ex ib) and certified to protection level Gb, which covers Zone 1 and Zone 2, and neither is certified for Zone 0.
Which gets security updates for longer?
The i.safe MOBILE IS940.1, by a wide margin. i.safe states security updates until Q4 2032 for it, and 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?
Only the i.safe MOBILE IS940.1, within its certificate’s limits and a charging range of 0 °C to +45 °C, for example on its IS-DS940.1 docking station. The i.safe MOBILE IS930.1 must be charged outside the hazardous area, at +5 °C to +35 °C, and its battery is not user-replaceable.
Is there a mining version of either tablet?
Yes, of both. The i.safe MOBILE IS930.M1 and the i.safe MOBILE IS940.M1 are also certified for Group I (underground mining). Check each mining version’s ingress rating with i.safe before ordering.
Do both have 5G?
No. The i.safe MOBILE IS940.1 has 5G NR and 4G LTE, and the i.safe MOBILE IS930.1 has 4G LTE and no 5G. Both have NFC and a 5 MP front camera.
How much do the i.safe MOBILE IS930.1 and i.safe MOBILE IS940.1 cost?
Prices depend on volume, configuration and region, so both are on request. Contact us for a price.
