Travel-ready 3-in-1 CO detector with temperature and humidity at a glance

Meet the PRIMBARBER 3-in-1 Portable CO Detector, a compact, rechargeable sensor designed for travelers, campers, and RV enthusiasts. It tracks carbon monoxide (0–500 PPM), ambient temperature (-10°C to 50°C / 14°F to 122°F), and humidity (5–95% RH) in real time, with a large HD display that makes air safety status easy to read from a car cabin, tent, or small living space. The device blends practical sensing with a tidy, portable form factor so you can stay informed on the go.

Smart detection you can rely on

Powered by a precision 3nm CO sensor, the unit refreshes data every 0.5 seconds for timely updates. The color and sound alerts indicate when conditions are Safe, Warning, or Danger, helping you respond quickly while you monitor values on the clear display.
