Fits and works fine
It fits and works. 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.
