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

The BW Clip H2S (BWC2-H) is a 2-year maintenance-free electrochemical single-gas personal monitor for hydrogen sulfide, worn in the breathing zone, with audible, visual and vibrating alarms at 10 ppm and 15 ppm — a monitoring device, not respiratory protection.

Why the BW Clip H2S is the industry-standard H2S clip

Hydrogen sulfide is toxic at low levels and quickly kills the sense of smell, so workers cannot rely on odor — they need a monitor that alarms at defined ppm points. The BW Clip H2S does exactly that: a 2-year maintenance-free electrochemical single-gas clip worn in the breathing zone, with a constant real-time H2S reading and audible, visual and vibrating alarms at 10 ppm and 15 ppm. Turn it on day one and it runs two years with no sensor or battery service. As H2S monitors go, this is the maintenance-free single-gas standard, and the gas detection guide and the best H2S monitor guide explain where it fits. It puts reliable H2S monitoring on each worker with no upkeep.

What the BW Clip H2S listing documents

From the published specs: a single-gas H2S electrochemical monitor; a 2-year maintenance-free run life with no battery or sensor replacement; alarms at 10 and 15 ppm that are audible (~95 dB), visual and vibrating; and a constant real-time reading. These are true hydrogen sulfide monitor and single-gas detector credentials in a maintenance-free H2S detector. Confirm the setpoints and activation on the listing.

How the BW Clip H2S compares to other gas detectors

For the single-gas CO clip, the BW Clip CO; for the single-gas O2 clip, the BW Clip O2; for a sealed 2-year 4-gas unit, the BW Clip4; for a datalogging 4-gas workhorse, the GasAlertMicroClip XL; and for a rugged H2S alternative, the GasAlertClip Extreme H2S. The Clip H2S vs GasAlertClip Extreme guide and the 4-gas vs single-gas guide help you choose.

Choosing the right gas monitor

Browse the gas detectors and personal gas detectors collections; for the coverage decision, the best personal gas detector guide; and for single-versus-multi coverage, the 4-gas vs single-gas guide, the area gas monitors collection, the gas leak detectors collection, and the combustible-detector vs leak-detector guide.

Where it fits by job and crew orders

The BW Clip H2S suits oil and gas, wastewater and sewer work, pulp and paper, and confined spaces where H2S is the primary hazard — see the best H2S monitor guide and the portable gas detectors collection for alternatives. Its fixed 2-year life and low per-worker cost make H2S monitoring easy to issue crew-wide. Confirm the alarm setpoints match your action levels on the listing, bump-test before use, and replace the unit at end of its 2-year life.
