Overview

Meet the Hembisen 3-pack carbon monoxide detectors, a compact, battery-operated safety solution designed for homes, kitchens, hotels, offices, and restaurants. Each unit features a clear digital display for quick readings and a loud, reliable alarm that helps you stay informed about potential CO presence. The three-pack provides versatile coverage for living spaces, work areas, and high-traffic zones, offering peace of mind through consistent monitoring.

Why the sensors make a difference

The ME2 high-precision electrochemical sensor delivers repeatable readings and stable performance, with a fast response to changes in carbon monoxide levels. This combination supports dependable awareness without constant recalibration.

• High-reliability electrochemical sensor
• Excellent repeatability and stability
• Sensitive response and rapid audible alert

Smart detection and clear alerts

Micro-processing intelligent recognition quickly identifies CO presence and triggers an 85 dB alarm to ensure occupants are promptly notified, even in noisier environments.

• 85 dB alarm for strong, audible notification
• Intelligent recognition for fast, accurate detection

Escalation times by CO concentration

The detectors follow established guidance for warning times across common CO scenarios, helping you respond with awareness rather than guesswork.

• 50 ppm: alarm within 60–90 minutes
• 100 ppm: alarm within 10–40 minutes
• ≥200 ppm: alarm within 1 minute

Energy-saving design

When ambient CO is not detected, the display automatically powers down and the unit enters a power-saving mode, preserving battery life while staying ready to alert.
