Honeywell SR-X2V Replacement Oxygen Sensor

Overview

Honeywell SR-X2V is a genuine BW Technologies by Honeywell replacement oxygen (O2) sensor engineered for the GasAlert family of portable multi-gas monitors. Covering a 0–30% volume oxygen measurement range, the Honeywell SR-X2V is factory calibrated and designed for rapid field replacement, restoring full oxygen deficiency and enrichment detection capability to GasAlert MaxXT II, MicroClip XL, Quattro and Micro 5 monitors used extensively across confined space entry and personnel safety programs.

As the official authorized partner and exclusive regional representative for Honeywell, Seven Star LLC proudly supplies genuine Honeywell SR-X2V replacement oxygen sensors to industrial plants throughout Oman and the GCC. Every sensor shipped from our Muscat-based facility is sourced directly through Honeywell’s authorized distribution channel, ensuring authentic electrochemical cell construction and full compatibility with existing GasAlert monitors already deployed across regional oil and gas, petrochemical and confined space entry safety programs.

Operating Principle

The Honeywell SR-X2V uses an electrochemical sensing cell that generates a current proportional to the partial pressure of oxygen diffusing through a gas-permeable membrane into the sensor housing. As ambient oxygen reacts at the working electrode within the cell, the resulting electrical current is processed by the host GasAlert monitor’s internal circuitry and displayed as a real-time percentage of oxygen by volume, triggering audible and visual alarms if the reading drops below or rises above pre-configured safety thresholds.

Because the electrochemical cell is a consumable component with a finite service life determined by internal electrolyte depletion, periodic sensor replacement is required to maintain measurement accuracy and alarm reliability. The SR-X2V is designed as a direct drop-in replacement for the SR-X10-C1 and SR-X10 legacy sensors, allowing safety teams to restore full monitor functionality quickly without recalibrating the entire instrument from scratch, minimizing the time personnel safety equipment spends out of service.

Engineering Design of the Honeywell SR-X2V

The sensor is housed in a compact cylindrical cartridge with gold-plated connection pins that mate directly into the corresponding slot inside the GasAlert monitor chassis, ensuring reliable electrical contact and correct polarity during installation. A printed caution label instructs technicians not to remove the protective covering prior to installation, preserving the electrochemical cell’s calibrated state until it is placed into active service inside the host instrument.

Physical dimensions and pin spacing are standardized across the GasAlert MaxXT II, MicroClip XT, MicroClip XL, Quattro and Micro 5 platforms, allowing a single sensor part number to service multiple monitor models across a facility’s safety equipment fleet. The sensor carries a two-year warranty from date of manufacture, giving safety managers a predictable replacement interval to budget for as part of routine gas detection equipment maintenance programs.

Key Features

The Honeywell SR-X2V replacement oxygen sensor delivers dependable performance around the following capabilities:

• Factory-calibrated electrochemical cell covers the full 0–30% volume oxygen measurement range.
• Direct drop-in replacement for legacy SR-X10-C1 and SR-X10 sensors simplifies fleet-wide upgrades.
• Compatible across GasAlert MaxXT II, MicroClip XT, MicroClip XL, Quattro and Micro 5 monitor platforms.
• Gold-plated connection pins ensure reliable electrical contact and correct polarity during installation.
• Quick cartridge-style replacement minimizes downtime for personnel gas detection equipment.
• Two-year manufacturer warranty supports predictable maintenance budgeting and replacement scheduling.
• Genuine BW Technologies by Honeywell construction ensures accurate, reliable oxygen deficiency alarming.
• Compact, standardized cartridge design supports single-part-number fleet servicing across monitor models.

Industrial Applications

The Honeywell SR-X2V is deployed across confined space entry programs, tank and vessel inspection, and general personnel gas detection duties in oil and gas, petrochemical and utility facilities where oxygen deficiency or enrichment presents a life-safety hazard. In Oman’s upstream and downstream oil and gas operations, as well as refineries, ports and industrial zones across Muscat, Sohar and Salalah, GasAlert monitors fitted with genuine SR-X2V sensors form a core part of confined space entry permit systems and personal protective equipment programs.

As the officially authorized partner for Honeywell in Oman and the GCC, Seven Star LLC distributes genuine SR-X2V oxygen sensors to HSE departments, safety equipment service providers and industrial contractors throughout the region, backed by regional warehouse stock and manufacturer-authenticated supply. Facilities across Sohar’s industrial port zone and Salalah’s free trade zone depend on Seven Star LLC for genuine BW Technologies by Honeywell sensors with confirmed calibration data and traceable sourcing.

Technical Specifications

Sensor Chemistry and Cell Identification

The cell supplied under the Honeywell SR-X2V part number is a 4OXV CiTiceL oxygen cell configured for a 0–30% volume span. CiTiceL is Honeywell’s own electrochemical cell line, originally developed by City Technology, so the replacement sensor and the host GasAlert instrument come from the same engineering family rather than from an aftermarket supplier reverse-engineering the pin-out. That matters in practice because a non-genuine oxygen cell can present the correct mechanical footprint while delivering a different output current per percentage of oxygen, which the monitor will accept during calibration and then track inaccurately as the cell ages.

Calibration, Bump Testing and Service Life

After fitting a new Honeywell SR-X2V, the monitor should be left to stabilise before a fresh-air calibration is performed at 20.9% oxygen by volume, and Honeywell BW recommends a functional bump test before each day’s use to confirm that both the sensor and the alarms respond. Fleets running a significant number of GasAlert instruments can automate that routine with Honeywell BW docking systems such as MicroDock II, which perform the bump test, record the result, and flag any instrument that fails. Galvanic oxygen cells of this class are consumed by their own reaction chemistry and are additionally shortened by sustained high ambient temperature and very low humidity, so facilities operating in Oman’s summer conditions should plan replacement intervals conservatively and store spare sensors in a cool, sealed condition with the protective covering left intact until installation.
