A18ST-EX Slim 10.1-Inch Explosion-Proof Android Tablet
At 20mm thin and 859g, the A18ST-EX is the lightest 10.1-inch tablet in our explosion-proof lineup.

Android 13 runs on a MediaTek MT8781, with 8GB+128GB standard.

Petrochemical Inspection Routes
Walk the whole unit with one device: open the inspection form, snap the nameplate, scan the valve tag, close the work order. The Ex ib IIC T4 Gb configuration covers IIC gases — hydrogen and acetylene included — so refinery and tank-farm routes are its home turf.
Combustible-Dust Facilities
For dust zones, order the Ex ib IIIC T95°C Db configuration — it is rated for Zone 21/22 work such as grain handling, powder processing and woodworking plants.
Mobile Maintenance and Work Orders
A 10.1-inch screen shows a full A4 manual page without pinching and zooming — 60% more display area than our 8-inch A80ST-EX. At 859g, technicians carry it barehanded; no hand strap needed for most routes.
Barcode and Asset Identification
NFC comes standard. Add the 2D scanner module if your tags are barcodes, or the UHF module to read RFID tags on valves and pumps from several metres away — no climbing, no touching.
Photo-Led Field Documentation
Attach annotated photos to any inspection record. Camera hardware varies by certified configuration — tell us your zone classification and we will quote the right BOM. (One reason photo quality differs between Ex tablets: the camera is inside the certified boundary, so "just use a better sensor" is a re-certification, not an upgrade.)
Mobile Fleet and Kiosk Applications
Mount it on a forklift or wall bracket (154×71.5mm VESA holes, M3 screws) and it becomes a fixed kiosk; our team pre-installs and locks down your APKs before shipping if you need managed devices.

Frequently Asked Questions about A18ST-EX ib IIC T4 Gb tablet
1. What is the A18ST-EX best suited for?
A18ST-EX is designed for mobile Android inspection, work orders, asset records, photos and data capture where a 10.1-inch screen is useful but a thinner, lighter device is preferred. It measures 20mm thin and 859g, with a built-in 10000mAh battery — no swap needed on a normal shift.
2. Which explosion-protection configurations are available for A18ST-EX??
Two routes: an Ex ib IIC T4 Gb petrochemical configuration (backed by certificate CCRI 23.7672X), and an ATEX II 2GD configuration marked Ex ib IIC T5 Gb for gas and Ex ib IIIC T95°C Db for dust.
3. Can A18ST-EX be used in ATEX Zone 1 gas areas?
Yes — the ATEX gas configuration is Category 2G with EPL Gb, which is exactly the Zone 1 (and Zone 2) rating. The certificate number and ambient range come with our quotation.
4. Can A18ST-EX be used in Zone 21 combustible-dust areas?
Yes — order the Ex ib IIIC T95°C Db configuration; EPL Db is the Zone 21 (and Zone 22) rating for conductive dust.
5. Is A18ST-EX suitable for Zone 0 or Zone 20?
No Zone 0 or Zone 20 claim should be made from Gb and Db markings. Those areas normally require a higher Equipment Protection Level.
6. Is IP68 the same as ATEX or explosion-proof certification?
No. IP68 addresses dust and water ingress under defined conditions. ATEX and Ex markings address ignition risk in explosive atmospheres. An ordinary IP68 tablet is not automatically suitable for a hazardous area.
7. Which interfaces and wireless functions are available?
You get Type-C, USB-A, a 3.5mm jack, a 12-pin POGO dock connector, Micro-SIM and a TF slot (up to 256GB), plus dual-band Wi-Fi 5 and full-band 4G LTE. Bluetooth is 5.2 on current production units.
