Honeywell BW Clip O2 Monitor — Maintenance-Free Oxygen Detector
The Honeywell BW Clip O2 monitor (BWC2-X) is a 2-year maintenance-free oxygen clip that alarms on both deficiency and enrichment — the personal gas detector for confined spaces and inert-gas areas where O2 levels can drop or spike. Turn it on and it runs two years with no service.

Where the Honeywell BW Clip BWC2-X fits

- Inert-gas and purged environments
- Cryogenic and welding-gas areas (displacement risk)
- Vessel and tank entry
- One clip per worker in O2-risk areas
What the Honeywell BW Clip BWC2-X detects (and what it doesn’t)
This monitor detects oxygen (O2) only, alarming on both deficiency and enrichment — it does not read CO, H2S or combustibles. Oxygen displacement often accompanies other hazards, so for full confined-space coverage use a wearable 4-gas unit such as the BW GasAlertMicroClip XL or pre-test with a Portable Gas Detectors instrument. For CO see the BW Clip CO; for H2S the BW Clip H2S. Bump-test with O2-deficient calibration gas.

Honeywell BW Clip single-gas family compared
| Model | Gas | Alarm set points | Service life | Street price |
|---|---|---|---|---|
| BW Clip H2S (BWC2-H) | H2S | 10 / 15 ppm | 2 yr sealed | ~$125 |
| BW Clip CO (BWC2-M) | CO | 35 / 200 ppm | 2 yr sealed | ~$131 |
| BW Clip O2 (BWC2-X) | O2 | 19.5 / 23.5 % | 2 yr sealed | ~$120 |
- Choose the BW Clip O2 for oxygen-deficiency and enrichment monitoring in confined and inert-gas spaces.
- For CO use the BW Clip CO; for H2S the BW Clip H2S.
- Need oxygen plus combustibles and toxics on one worker? Use the GasAlertMicroClip XL or BW Clip4.
Frequently asked questions
What does the Honeywell BW Clip O2 monitor detect?
Oxygen (O2) only, alarming on both deficiency (19.5%) and enrichment (23.5%). It does not read other gases.
Why monitor oxygen enrichment as well as deficiency?
High oxygen dramatically increases fire risk; the BW Clip O2 alarms at 23.5% as well as the 19.5% low point, covering both hazards.
How long does the BW Clip O2 last?
Two years of continuous use with no battery or sensor replacement; replace the whole unit at end of life.
Is one oxygen monitor enough for confined-space entry?
Oxygen is only one hazard — confined spaces also need combustible and toxic testing. Use a 4-gas unit such as the GasAlertMicroClip XL and pre-test with a Portable Gas Detectors instrument.
Do I still need to bump-test it?
Yes — bump-test with O2-deficient calibration gas to confirm the sensor and alarms respond, even though no sensor or battery service is required.
Where should it be worn?
In the breathing zone, clipped to the collar or upper chest within about 12 inches of the nose and mouth.
Is the BW Clip O2 rechargeable?
No — it is a sealed 2-year maintenance-free unit, which keeps cost per worker low and removes service downtime.
What alarms does it use?
Audible (~95 dB), visual red-LED and vibrating alarms at the 19.5% and 23.5% set points.
Can one unit cover several workers?
No — issue one clip per worker. For area coverage use a Area & Transportable Gas Monitors monitor; for pre-entry use a Portable Gas Detectors instrument.
What does it not detect?
Anything other than oxygen. For CO use the BW Clip CO; for H2S the BW Clip H2S; for multiple gases a 4-gas wearable.
Is it in stock and how does it ship?
Use the Amazon buy button for live availability and delivery timing through our fulfillment partner.
Does it include calibration gas?
No — O2-deficient calibration gas and docking are sold separately for bump testing and verification.
