BW SR-X2V Oxygen Sensor for GasAlert MicroClip & Max – SR-X2V (40XV) Direct-Replacement, Electrochemical O2

The SR-X2V (40XV) by BW is a factory-new CiTiceL oxygen sensor built to fit compatible GasAlertMicroClip and GasAlert Max instruments. It replaces depleted O2 sensing elements so your portable monitor can again read ambient oxygen levels accurately. Packaging, cap color, or body finish may vary by batch, but the sensing specifications and connector compatibility match BW’s replacement standards.

Which BW devices accept the SR-X2V (40XV) oxygen sensor?

This sensor is intended for a range of BW portable detectors. Confirm compatibility by matching the sensor part number (SR-X2V / 40XV) with your instrument’s sensor list or service manual before installation.

• Typical fits: GasAlertMicroClip XL and GasAlert MicroClip XT models.
• Also used in some GasAlertMax XT II units where specified by BW.
• International product versions may have different labeling—verify part number rather than color.

How do I install and calibrate the replacement sensor?

Installation is straightforward: remove the device cover, swap the old sensor for the new SR-X2V, secure the housing, and follow the detector’s startup prompts. Always perform a bump test and full calibration per your instrument’s guidelines after sensor replacement.

• Power down the monitor if recommended by the manual before changing the sensor.
• Seat the sensor connector fully and reassemble the housing to ensure a proper seal.
• Run a bump test with known gas or perform a span calibration as required by site procedures.

What performance and safety considerations should I know?

The SR-X2V is a consumable electrochemical oxygen sensor; lifetime depends on exposure, operating temperature, and contamination. Keep spare sensors on hand and follow manufacturer service intervals to maintain instrument reliability.

• Replace sensors at end-of-life or after failed bump/calibration checks.
• Avoid exposing the sensor to silicone, leaded compounds, or heavy hydrocarbons that can shorten life.
• Store spares in original packaging at recommended temperature and humidity levels.

Who is this for: Maintenance technicians, safety officers, and plant personnel who manage BW/GasAlert portable gas detectors and need an OEM-compatible oxygen sensor to restore or maintain accurate O2 readings. It’s also suitable for resellers and service centers stocking replacement parts for GasAlertMicroClip XL, MicroClip XT, and GasAlertMax XT II series that list SR-X2V or 40XV as the specified oxygen sensor.
