Overview

The Hervimo 3-in-1 carbon monoxide detector is a compact, portable companion designed to monitor critical air factors wherever you are. It combines CO sensing with temperature and humidity readings, giving you a clear snapshot of room conditions without complicated setup.

What it tracks

Real-time measurements cover carbon monoxide levels from 0 to 999 ppm, ambient temperature from -40 to 176 Fahrenheit, and relative humidity from 0 to 99 percent. The device updates data continuously, so you can react quickly to changes.

Clear alerts you can trust

  • LED indicators in green, yellow, and red display safe, hazardous, and danger levels at a glance
  • Audible alarm intensifies as CO rises, helping you notice risk even if you’re not looking at the display

Smart, flexible placement

  • Tabletop or flat-surface placement for living rooms, bedrooms, or kitchens
  • Magnetic base for easy attachment to metal surfaces like fridges or vehicles
  • Included lanyard for hands-free carry during travel, camping, or road trips

Long-lasting power, ready when you need it

A 1000 mAh rechargeable battery supports Type-C charging and up to 480 hours of standby time with a low brightness mode after inactivity. A quick double-press can toggle the alarm if you need to silence alerts temporarily.
