Intrinsically Safe Mobile Phone Distributor in Surabaya
Surabaya is the capital of East Java and home to Tanjung Perak, Indonesia's second-largest port. The Port of Tanjung Perak in north Surabaya is Indonesia's second-busiest seaport, on a site where a modern port facility was first built in 1910, giving contractors a major sea gateway to eastern Indonesia. An intrinsically safe mobile phone distributor in Surabaya and the Gresik industrial area would carry the IS-04Z1 to these buyers once certification completes.

The term · intrinsically safe
What “intrinsically safe” means for a smartphone
Intrinsic safety limits the electrical and thermal energy in a circuit so that neither a spark nor a hot surface can ignite a gas or dust atmosphere, even when a fault occurs. The ib level, used for Zone 1, tolerates one fault. It is the usual way to make a handheld device that a worker carries continuously through a hazardous area.
The IS-04Z1 is designed on this principle for Zone 1 and Zone 21 (marking target II 2 G Ex ib IIC T4). Intrinsic safety is a design basis, not a certificate: certification is in progress and none has been issued yet.
In Surabaya and the Gresik industrial area. Operators at chemical plants and port fuel handling walk between tanks, process areas and quays on rounds. A handheld designed for intrinsic safety could hold checklists and photos in one device where its gas marking fits. Dust areas at cement works need separate assessment.

Questions · Surabaya
Frequently asked questions
Can we buy an intrinsically safe mobile phone in Surabaya today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does an intrinsically safe mobile phone in Surabaya cost?
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
What does ‘intrinsically safe’ mean for the IS-04Z1?
The circuits are designed to limit energy so a spark or hot surface cannot ignite a gas or dust atmosphere, even with one fault (level ib, Zone 1). Certification of that design is in progress.
Which areas at Surabaya and the Gresik industrial area would use it?
Likely candidates are port fuel and chemical handling, fertiliser and chemical plants, cement plant dust areas, industrial estate chemical plants. Which areas are classified, and to what zone, is set by the site operator's own area classification drawings.
How do I become a SAMS distributor for Surabaya and the Gresik industrial area?
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for Surabaya and the Gresik industrial area.
Is the climate in Surabaya hard on handheld equipment?
Temperatures are steady, around 23 to 31 degrees, but the wet season from October to May brings heavy rain and humidity, and coastal air adds salt. Devices typically need good ingress protection and cleaning routines for exposed use.
Which industrial areas around Surabaya matter for hazardous-area equipment?
The wider metropolitan area includes Gresik, Sidoarjo and other satellite cities with port-side and industrial plants. Typical hazards include fuel, chemical and bulk handling, so ask each operator for its zone classification and device approval requirements.
Does Gresik count as part of the Surabaya market?
Yes in practice. Gresik lies about 25 kilometres north-west of Surabaya, and its fertiliser and cement works are major buyers of safety equipment. Requirements are set plant by plant. Confirm with each site operator's safety function.
