## Description

Brand New CiTiceL BW Oxygen Sensor SR-X2V 40XV Note: The graphic of this sensor is an example only and sensor cap/body colour may vary depending upon gas sensor type ordered or manufacturing modification.

Review: 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.
Review: Great for my BW meter - Great replacement sensors for our BW meters. Affordable Oxygen sensors for sure.

A: No, it replaces a sensor in a 4 gas monitor that monitors the H2S, CO, LELs and 02 level in air, however if you want to buy it as a portable $650.00 smoke alarm it would work but not as well as the standard smoke alarms

**Q: will this replace a 40xv citicel aay80-390?**
A: Yes, it is.

**Q: I need three sensors.  the ones that need replaced are city technology 5nf, 5fo, and a5f (co, no, and o2). can you supply these?**
A: Yes, we do have them in stock, 5NO, 5FO and A5f sensors.
