BWCLIP 2 year O2 19.5-23.5 | BW

The BW Clip 2-Year O? detector, model BWC2-X, is a robust, single-gas portable monitor designed by Honeywell / BW Technologies. It is optimized for measuring oxygen (O?) levels in the atmosphere (0 - 25 vol %) and provides an alarm range of 19.5% (low) to 23.5% (high) by default. 

What makes this device powerful is its maintenance-free operation — once activated, it runs continuously for up to 2 years, without requiring sensor replacement or recharging.

Key Features

Maintenance-Free Operation

• Built to last 2 years of continuous operation.
• No need for routine sensor changes, or battery swaps.

Alarm Mechanism

• Low Alarm: 19.5% O? (by default) 
• High Alarm: 23.5% O? (by default)
• Alarm signals: audible (95 dB), vibration, and wide-angle LED flash.

Self-Test & Diagnostics

• Uses Reflex™ automated self-test: every 24 hours it checks battery, sensor, and electronics automatically.
• If a fault is detected, it alerts you or may shut down to prevent unsafe use.

Event Logging

• Logs up to 35 most recent gas events (alarms) and bump test results.
• These logs are useful for compliance, audits, or safety reviews.

Device Management (“Concept Controls”)

• Compatible with MicroDock II docking station.
• Compatible with IntelliDoX system: allows configuration of alarm set-points, bump-testing, and fleet-level tracking.
• You can pre-configure low/high alarm levels before activation (using the management system) to match your safety requirements.

Durable, Rugged Design

• Compact dimensions: 1.6″ × 2.0″ × 3.4″ (4.1 × 5.0 × 8.7 cm) 
• Light weight: 92 g (3.2 oz) 
• Operating temperature: –20°C to +50°C for the O? version. 
• Humidity: 5%–95% RH (non-condensing) 
• Ingress protection: IP66 / IP67, making it dust-tight and water-resistant / submersible to some extent.

Sensor Technology

• Electrochemical O? sensor designed for 0–25 vol% measurement.
• Default alarm levels: 19.5% and 23.5%, but these can be reconfigured before use. 

Certifications & Safety

• Intrinsically safe: Class I, Division 1, Groups A/B/C/D. 
• Explosion protection: ATEX and IECEx certified (Ex ia IIC T4 Ga).
• 1-year shelf life (for O? model) before activation. 

Use Cases / Applications

• Confined Space Entry: Monitoring oxygen in tanks, vessels, or underground spaces to avoid asphyxiation or dangerous oxygen-rich atmospheres.
• Industrial Sites: Ensuring safe oxygen levels in chemical plants, refineries, manufacturing operations.
• Rescue / Emergency Teams: For first responders entering unknown or potentially oxygen-deficient environments.
• Maintenance Crews: During maintenance in areas where oxygen depletion or enrichment might occur.
• Routine Safety Monitoring: For any workforce needing continuous, simple O? monitoring without the burden of frequent maintenance.

Benefits

• Low Total Cost of Ownership: No periodic sensor or battery replacements for 2 years.
• Reliability: Self-diagnostics ensure the detector is operational and healthy.
• Ease of Use: One-button activation → simple to deploy.
• Strong Alerts: Audible + visual + vibration ensures you will notice alarm conditions.
• Data & Compliance: Logged events help you with audits, safety records, and compliance.
• Flexible Integration: With IntelliDoX/MicroDock II, you can manage multiple units, bump test them, and configure alarms as needed.

Possible Limitations / Considerations

• Since it is maintenance-free, once activated, you can’t “turn it off” and reuse later beyond its 2-year life.
• Its default alarm set-points (19.5% and 23.5%) may not suit all use-cases — make sure these match your safety protocols or configure them before activation.
• Though robust, event logging is limited (35 events) — if you need more detailed historical data, plan your bump test / maintenance schedule accordingly.
• It’s a single-gas detector, so you’ll need separate devices if you also want to monitor other gases (H?S, CO, etc.)
