Servomex Micro i.s. 5100 Portable Oxygen Analyzer
Overview
The Servomex Micro i.s. 5100 Portable Oxygen Analyzer is a compact, intrinsically safe instrument engineered for spot-checking and continuous monitoring of oxygen concentration in potentially explosive atmospheres. Certified to ATEX Category 1 (Zone 0), IECEx, and cus standards, the Micro i.s. 5100 is one of the few portable analyzers rated for use in the most hazardous Zone 0 locations, giving plant personnel confidence when verifying inert gas purging, tank atmospheres, and confined space entry conditions where flammable vapors may be present alongside the oxygen being measured.
Seven Star LLC supplies the Servomex Micro i.s. 5100 as an authorized partner to end users across Oman and the wider GCC, supporting oil and gas, petrochemical, and marine operators who need dependable, factory-calibrated instruments backed by genuine spare parts and applications assistance. Every unit shipped from Seven Star LLC is sourced directly through Servomex’s authorized distribution channel, ensuring full warranty coverage and traceable certification documentation for safety audits in Muscat, Sohar, and Salalah industrial zones.
Measurement and Operating Principle
The Micro i.s. 5100 uses Servomex’s proven paramagnetic oxygen sensing technology, which exploits the unique paramagnetic susceptibility of oxygen molecules to generate a highly stable, drift-resistant signal without consuming the sample or relying on a limited-life electrochemical cell. This approach delivers long-term measurement stability and eliminates the periodic cell replacement costs associated with older galvanic oxygen sensors, reducing total cost of ownership for operators running frequent hazardous-area inspections.
An internal sample pump draws gas through the sensor for pumped operation, while the analyzer can also be configured for non-pumped, ambient diffusion sampling depending on the application. Readings are displayed on an intuitive, engineer-friendly interface capable of storing up to 200 measurements for later download and review, supporting compliance recordkeeping for confined space entry permits and hot work clearances.
Engineering Design of the Servomex Micro i.s. 5100
Housed in a rugged, ergonomic enclosure measuring 160mm wide by 185mm high by 140mm deep and weighing between 1.8kg and 2.3kg depending on configuration, the Micro i.s. 5100 is built to withstand the physical demands of field use in refineries, offshore platforms, and tank farms. The analyzer is powered by a high-grade, long-life Li-Ion rechargeable battery pack delivering up to 18 hours of continuous run time, allowing extended shift coverage without mid-shift charging interruptions.
The instrument is available in multiple certified variants (5100 SV01, SV02, and user-configured builds; 5111 SV01 and SV02) to match specific hazardous-area classification and sample-conditioning requirements. An IP65-rated housing protects internal electronics from dust and water ingress, while an included protective carry bag and optional sample probe accessories round out a complete field-ready package for oxygen verification work across Oman’s industrial and marine sectors.

Industrial Applications
The Micro i.s. 5100 is widely deployed for confined space entry verification, inert gas purging checks, and tank atmosphere testing across Oman’s oil and gas production facilities, refineries, and LNG terminals, where flammable hydrocarbon vapors and low-oxygen atmospheres frequently coexist. Its Zone 0 intrinsic safety certification makes it one of the few instruments trusted for direct measurement inside vessels and pipework sections classified as continuously hazardous, a requirement increasingly specified in permit-to-work systems across Sohar and Salalah free zone facilities.
As an authorized Servomex partner, Seven Star LLC supports marine, petrochemical, and offshore operators throughout the GCC with genuine Micro i.s. 5100 units, factory-trained calibration guidance, and rapid access to certified replacement parts. This authorized-partner relationship ensures that safety-critical oxygen verification equipment deployed on Omani platforms and vessels meets both manufacturer specification and local regulatory expectations for hazardous-area instrumentation.

Why Choose Seven Star LLC for Servomex Portable Gas Analyzers
A Zone 0 intrinsically safe rating is only meaningful if the exact certified variant (SV01, SV02, or a user-configured build) matches the specific hazardous-area classification your permit-to-work system requires, since the wrong variant can leave a site technically non-compliant even though the base instrument looks identical. Seven Star LLC confirms the correct Micro i.s. 5100 variant and sampling configuration (pumped versus non-pumped AFCD) against your actual confined-space and purge-verification procedures before order confirmation, backed by our authorized Servomex partnership across Oman and the wider GCC. We also support oil, gas, and marine operators in Muscat, Sohar, and Salalah with planning spare battery packs and calibration gas supply so field teams running frequent hazardous-area checks are never held up waiting on consumables.
