Careful as the great price might be due to brokers buying up sensors from suppliers that are near expiration. Let's see how long it lasts. ==== Copy paste from Google: The oxygen (O2) sensor in a Honeywell BW Gasalert Microclip XL typically has a lifespan of two years from activation, according to BW Gas Monitors. The O2 sensor's shelf life is 6 months. === So mine is now active on 15 May 2025 and we will see if it stayed calibrated for 2 years. ## Frequently Bought Together - BW SR-X2V - 4OXV Oxygen (O2) Sensor - BW Technologies SR-W-MP75C Replacement MICROpeL Combustible (LEL) Sensor, 0 to 100 Percent LEL Measuring Range - BW Technologies SR-H-MC Replacement MICROceL Sensor, Hydrogen Sulfide H2S, 0 to 200 ppm Measuring Range --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/389098683-bw-sr-x2v-4oxv-oxygen-o2-sensor](https://www.desertcart.kr/products/389098683-bw-sr-x2v-4oxv-oxygen-o2-sensor) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-25*
