Hervimo 3-in-1 Carbon Monoxide Detector | Portable CO Detector with Temperature & Humidity, Magnetic Mount, Rechargeable Battery

Compact 3-in-1 Monitoring for Safer Spaces

Meet the Hervimo 3-in-1 Carbon Monoxide Detector, a compact, portable device that tracks carbon monoxide levels, temperature, and humidity in real time. Built with an advanced electrochemical sensor, it delivers steady measurements across three critical parameters, giving you a clear snapshot of your immediate air conditions and helping you respond quickly to changes in your environment.

What It Measures

• CO detection range: 0–999 ppm
• Temperature: -40°F to 176°F / -40°C to 80°C
• Humidity: 0–99% RH

Real-time updates keep you informed as conditions evolve, whether you’re at home, in a hotel, or on the go.

Clear Alerts, Easy to Read

The device uses three color indicators plus an audio-visual alarm to communicate levels at a glance. Green indicates safe levels (0–49 ppm), Yellow signals a heightened level (50–99 ppm), and Red activates the alarm (100–500 ppm). The alarm is set to trigger at 50 ppm by default, and you can toggle it with a simple double-press for tailored monitoring in quiet spaces or busy environments.

Flexible, Portable Placement

• Flat-surface use on a table or shelf in living rooms, bedrooms, or kitchens
• Magnetic base for quick attachment to refrigerators, metal surfaces, or vehicles
• Included adjustable lanyard for hands-free carrying during outdoor activities like camping, hiking, or road trips

This versatility means you can position the detector where you spend most of your time, keeping essential readings within reach.

Power That Keeps Up With Your Day

• Large 1000 mAh rechargeable battery with USB-C charging
• Power-saving mode lowers brightness after 1 minute of inactivity to extend standby life
• Up to 480 hours of standby time on a single charge, depending on use

Designed for long-term reliability, the Hervimo detector minimizes replacements while staying ready when you need it.

Audible-Visual Clarity

In addition to the LED color cues, the detector emits a high-decibel alert that intensifies as CO levels rise. This combination of visuals and sound helps you notice changes quickly, supporting timely awareness in busy rooms or during sleep.

Real-Life Scenarios

Whether you’re stabilizing the air in a compact apartment, monitoring a hotel room during travels, or keeping a vehicle cabin safer on road trips, this 3-in-1 detector offers continuous, at-a-glance insight. The built-in temperature and humidity readings complement CO data, supporting general environmental awareness in everyday life.
