Field devices by type

Five device categories are listed on this site, matching the storefront main categories. Each category page names only the models that have a published specification record; categories without a surviving model record are presented as inquiry pages, so buyers can confirm availability before specifying a model.

Intrinsically Safe Smartphones

Intrinsically Safe Tablets

Four models with listed specifications: XPad_08, Ex Tablet08, Ex Tablet09 and Ex Tablet10. The tablet range carries the strongest manufacturer-page record on this site, with two models documented on the manufacturer's website.

Intrinsically Safe PDA Terminals

Where these devices are used

The manufacturer's website states the following field uses for these devices: oil, natural gas, chemical and pharmaceutical sites, oil depots and tank farms where flammable gases may be present, plus supporting work including outdoor construction, pipeline inspection, dispatch communication, office automation, inspection positioning and data collection. The industry guides on this site stay inside that list. No other industry is claimed, and no customer or project is named anywhere on this site, because no project record is published.

For buyers, the practical consequence is simple: start from the job, not from the device. A pipeline inspection team needs a large readable screen and long battery life; a depot patrol team needs one-handed operation and fast identification; a dispatch team needs reliable voice and messaging. The phone, tablet and PDA comparison walks through those job dimensions without inventing performance rankings, and each detail page lists only the parameters its own source actually published.

Listed specifications, stated as published

Every specification table on this site carries its source level. Manufacturer-website records are introduced with "the manufacturer's website states". Where a published entry is incomplete, the page says so instead of filling the gap. Where a parameter is not published for a model, the page does not borrow it from another model.

That discipline matters for hazardous-area buying. A screen size, battery capacity or ingress rating that belongs to one model must never be read as a property of the whole range. If a detail your site requires is missing from a model's table, the inquiry checklist tells you exactly what to ask: confirm the configuration before ordering.

Before you send site requirements

Three confirmations belong in every quote request for this category, and they are repeated on every page of this site because they decide whether a device can be deployed at your site at all:

  • Confirm MOQ and lead time in your quote request.
  • Confirm certification scope and marking for your target market before ordering.
  • Confirm the model availability for your site before ordering.

How buyers use this site

Buyers typically arrive with a job, not a model name. The fastest path is: pick the device class on the all devices page, read the two or three detail pages in that class, and note which parameters each listing actually publishes. Where a parameter is missing, the detail page says so, and the before-you-order checklist turns the gap into a question for the quote request. That loop — read what is published, ask about what is not — is the whole buying method this site supports, and it avoids the most common failure in this category: specifying a device on the basis of a parameter that belongs to a different model.

Site operators planning a multi-site rollout should read the industries page first, then the application guides for their sectors, then the comparison guide. Procurement teams comparing suppliers should keep the inquiry questions identical across suppliers, so answers can be compared line by line. A supplier answer that names the configuration, the quantity, the price basis, the lead time, the marking and scope for your market and the warranty scope is an answer that can be ordered against; category language without those specifics is not.

How to read this site

Specification source levels at a glance

Manufacturer-website record

Product pages on the manufacturer's website, introduced with "the manufacturer's website states". Two tablet models carry this level: XPad_08 and Ex Tablet08. Their parameters are quoted directly from those pages.

Third-party listing record

Manuals and listing pages for six detail models: each detail page lists that model's parameters.

Two rules govern every table on this site. First, a parameter is never borrowed from one model to another: a battery figure, a screen size or a camera set belongs to the model whose source published it. Second, an unpublished parameter is a question, not an assumption: the before-you-order checklist turns each gap into a named question for the quote request. Buyers who follow those two rules cannot be misled by a range-wide reading of a single model's table.
