Overview

High Performance Portable Oxygen Analysis for Hazard-Rated Locations

The SERVOFLEX Micro i.s. 5100 provides high-sensitivity percentage oxygen analysis within an Intrinsically Safe (i.s.) framework. Engineered for hazardous zones, it is capable of processing both flammable and toxic gas samples without requiring a pre-measurement purge.

This unit features an intuitive interface, internal data logging for up to 200 records, and an extended 18-hour battery life, ensuring operational reliability for long-duration field tasks.

Enhanced Safety for the Most Dangerous Locations

In explosive atmospheres, the deployment of reliable analytical solutions is paramount to maintaining safety and measurement efficiency. Intrinsically safe (i.s.) certified instruments are essential for critical processes, including catalytic regeneration, decoke cycles, and combustion optimization.

By prioritizing devices that offer extended battery life, low maintenance requirements, and an intuitive user interface, operators can drive down costs without compromising on technical rigor or compliance.

A No-Compromise Solution

The SERVOFLEX Micro i.s. combines a safety-optimized, intrinsically safe architecture with industry-leading oxygen monitoring sensitivity. Designed specifically for hazardous environments, this portable solution is available in both pumped and non-pumped configurations to suit diverse sampling requirements.

Its feature-rich design simplifies complex field testing, offering a seamless balance of high-performance analytics and operational usability.

Works Hard

Contrived for maximum uptime and operational durability, the Micro i.s. features high-performance Li-Ion rechargeable batteries as a standard component. The device includes an integrated digital LCD notepad capable of storing up to 200 individual measurements to further streamline field workflows, allowing for rapid testing and data management without the need for external logging tools.
