BW Oxygen (O2) Sensor SR-X2V (40XV) Replacement Cell — GasAlert MicroClip XL/XT Compatible, Electrochemical

This SR-X2V (also referenced as 40XV) oxygen sensor from BW (CiTiceL technology) is a brand-new, factory-style replacement cell compatible with select GasAlert series instruments. It swaps into approved BW detectors to maintain reliable oxygen readings in work environments where oxygen monitoring is required. Note that the sensor appearance — cap or body color — may differ by manufacturing batch or sensor variant; the pictured graphic is illustrative only.

Which detectors work with the SR-X2V (40XV) oxygen sensor?

The SR-X2V is designed for specific BW GasAlert models and other compatible instruments that accept the 40XV sensor format. Confirm compatibility by checking your detector’s manual or the model list before purchase.

• Fits: GasAlert MicroClip XL and GasAlert MicroClip XT
• Also used in some GasAlert Max XT II units
• Cross-check part numbers and instrument compatibility prior to installation

How easy is it to replace and activate the oxygen sensor?

Sensor replacement is straightforward: remove the old sensor, insert the SR-X2V, and follow your detector’s onboard prompts or calibration routine. Most instruments will recognize the new cell and request a calibration or bump test to verify performance.

• Tool-free swap in many detector models
• Run a bump test or full calibration after installation
• Observe warm-up period per instrument instructions

What performance and handling details should I expect?

The SR-X2V delivers standard electrochemical oxygen sensing performance consistent with BW/CiTiceL specifications. It is sold new and should be handled and stored according to manufacturer recommendations for optimal shelf life and service life.

• Electrochemical O2 sensing for ambient oxygen measurement
• New, factory-manufactured cell (not refurbished)
• Store away from extreme temperatures and contaminants

Are there regional differences or special ordering notes?

International versions of gas-detection products may have different packaging, language, or labeling details and are sometimes supplied under separate terms. Always verify the sensor’s fit and specifications for your local instrument and regulations.

• International products may vary in labeling or instructions
• Check local compatibility, age ratings, and warranty conditions
• Pictorial representations may not exactly match the shipped item

Who is this for: The BW SR-X2V (40XV) oxygen sensor is intended for safety technicians, maintenance personnel, and organizations that own compatible BW GasAlert portable detectors and need a reliable replacement O2 cell to maintain compliance, ensure worker safety, and keep detectors functioning accurately. Purchase this sensor when your device indicates sensor end-of-life, after an instrument failure diagnosis, or during routine maintenance to restore dependable oxygen monitoring.
