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.
Real-time updates keep you informed as conditions evolve, whether you’re at home, in a hotel, or on the go.
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.
This versatility means you can position the detector where you spend most of your time, keeping essential readings within reach.
Designed for long-term reliability, the Hervimo detector minimizes replacements while staying ready when you need it.
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.
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.
