Honeywell BW Clip H2S Monitor — BWC2-H Single-Gas (2-Year Maintenance-Free)

Honeywell BW Clip H2S Monitor — Maintenance-Free Single-Gas Detector

The Honeywell BW Clip H2S monitor (BWC2-H) is a 2-year maintenance-free single-gas clip worn in the breathing zone — the industry-standard personal gas detector for hydrogen sulfide exposure. Turn it on once and it runs for two years with no sensor or battery service.

The Honeywell BW Clip BWC2-H is a 2-year maintenance-free, electrochemical single-gas personal monitor for hydrogen sulfide (H2S), with audible, visual and vibrating alarms at 10 and 15 ppm.

Key features

• Worn in the breathing zone to alarm on hydrogen sulfide (H2S) exposure
• Runs continuously for 2 years with no battery or sensor replacement — turn it on day one and use it
• Audible (~95 dB), visual red-LED and vibrating alarms at 10 ppm and 15 ppm
• Highest-reviewed personal monitor we stock (990+ ratings, 4.7 stars)
• Constant real-time H2S reading on the display
• Compatible with IntelliDoX and MicroDock docking for automated bump tests

Specifications

Where the Honeywell BW Clip BWC2-H fits

• Oil-and-gas and wellsite work
• Wastewater and sewer entry
• Pulp, paper and refinery areas
• Tank and vessel work with H2S risk
• Issuing one clip per worker across a crew

What the Honeywell BW Clip BWC2-H detects (and what it doesn’t)

This monitor detects hydrogen sulfide (H2S) only — it does not read CO, O2, combustibles or any other gas. If a worker faces several hazards, choose a wearable 4-gas unit such as the BW GasAlertMicroClip XL or the sealed BW Clip4, or pre-test a space with a Portable Gas Detectors instrument. For carbon monoxide instead, see the BW Clip CO; for oxygen, the BW Clip O2. Bump-test with H2S calibration gas; docking via IntelliDoX/MicroDock automates it.

Honeywell BW Clip single-gas family compared

• Choose the BW Clip H2S when hydrogen sulfide is the dominant hazard.
• Pick the BW Clip CO for carbon-monoxide exposure, or the BW Clip O2 for oxygen.
• Need several gases on one worker? Step up to the GasAlertMicroClip XL or BW Clip4.

Frequently asked questions

What gas does the Honeywell BW Clip H2S monitor detect?

Hydrogen sulfide (H2S) only, with alarms at 10 and 15 ppm. For multiple gases on one worker, use a wearable 4-gas unit like the GasAlertMicroClip XL.

How long does the BW Clip H2S last?

It runs continuously for two years with no battery or sensor replacement. At end of life you replace the whole unit — that is the maintenance-free design.

Do I still need to bump-test a maintenance-free monitor?

Yes — bump-test to confirm the sensor and alarms respond. The unit needs no sensor or battery service, but bump testing verifies it is working; IntelliDoX/MicroDock docks automate it.

Where should I wear the BW Clip?

In the breathing zone — clipped to the collar or upper chest within about 12 inches of the nose and mouth — so it reads the air the worker actually breathes.

Is the BW Clip H2S rechargeable?

No — it is a sealed 2-year unit, not rechargeable or serviceable. The trade-off is zero maintenance and the lowest cost per worker over its life.

What alarms does it have?

Audible (~95 dB), visual red-LED and vibrating alarms trigger at the 10 ppm and 15 ppm set points, so alerts register in loud or low-visibility work.

Can one BW Clip cover a whole crew?

No — each worker needs their own clip for personal exposure. For area or pre-entry coverage use a Area & Transportable Gas Monitors monitor or a Portable Gas Detectors instrument.

What is the difference between the BW Clip and the BW Clip4?

The BW Clip is single-gas (H2S here); the BW Clip4 reads four gases (O2, LEL, CO, H2S) in the same 2-year maintenance-free format.

Does it log data?

Yes — it logs alarm events, which can be downloaded via the docking system for compliance records.

Is it in stock and how does it ship?

Use the Amazon buy button for current availability and delivery timing through our fulfillment partner.

Does it come with calibration gas?

Calibration gas and docking are sold separately. Plan to add H2S calibration gas (and a dock if you want automated bump tests) for your program.

Is the BW Clip suitable for confined-space entry?

It provides personal H2S coverage during work, but confined-space entry also requires pre-entry atmospheric testing — use a Portable Gas Detectors 4-gas instrument for that.
