BWCLIP 2 year SO2 5-10 | BW

The BW Clip 2-Year SO? Single Gas Detector (Model BWC2-S) from Honeywell / BW Technologies is a compact, rugged, and maintenance-free personal gas monitor designed to detect sulfur dioxide (SO?). It offers reliable protection for up to 2 years without needing sensor changes or battery replacements.

Key Features

Maintenance-Free Operation

• The detector runs continuously for up to two years.
• No need to change the battery or sensor during its life.

Alarm System

• Triple-mode alarm system: audible (95 dB) + vibration + wide-angle visual flash.
• Default low/high setpoints: 5 ppm (low) / 10 ppm (high) for SO?.
• Alarm set-points can be reconfigured (for example, 2–20 ppm) using a docking / management system.

Self-Test & Diagnostics

• Automatically performs a self-check every 24 hours to verify sensor, electronics, and battery. 
• If a fault is detected, it can shut down to prevent unsafe operation.

Event Logging

• Stores the 35 most recent gas events (alarms) and bump test results.
• Useful for compliance tracking and auditing.

Hibernation Mode

• Supports a hibernation case or IntelliDoX system, which lets you “sleep” the detector when not in use — preserving its 2-year life.
• Helps extend useful life during downtime.

Rugged & Durable Design

• Ingress Protection: IP66 / IP67 — dust-tight and water-resistant.
• Operating temperature for SO?: –30 °C to +50 °C.
• Size: ~1.6″ × 2.0″ × 3.4″ (4.1 × 5.0 × 8.7 cm), Weight: ~ 92 g.

Sensor Technology

• Uses a SureCell™ dual-reservoir sensor, which provides better response time, longevity, and reliability compared to standard electrochemical sensors.
• Measuring range: 0 – 100 ppm SO?. 

Certifications & Safety Compliance

• Certified for hazardous locations (ATEX, IECEx).
• Compatible with Honeywell’s management systems: MicroDock II, IntelliDoX, SafetySuite for bump testing, configuration, and fleet management.

Applications & Use Cases

• Industrial safety: Monitoring SO? in chemical plants, refineries, or manufacturing facilities.
• Confined space entry: Useful where sulfur dioxide might accumulate (e.g., tanks, vessels).
• Environmental monitoring: For workplaces where SO? is a potential hazard (e.g., in flue gas, emissions, or scrubbers).
• Emergency response / Hazmat: Lightweight and reliable for responders working in SO? risk zones.

Benefits & Why Choose This Model

• Long-term protection: 2-year life without maintenance means fewer interruptions and lower operating costs.
• High reliability: Self-testing ensures the detector is always functioning correctly.
• Compact & portable: Easy to clip onto clothing / gear, making it ideal for personal gas monitoring.
• Strong alert mechanisms: Multiple alarm modes make sure dangerous conditions are visibly and audibly flagged.
• Management-ready: Use with docking or fleet systems to manage many detectors easily.
• Durable build: Robust housing and IP rating make it suited for tough industrial environments.
