PRIMBARBER Portable 3-in-1 CO Detector — 43-Hole Monitor with Temp & Humidity for Travel, RV, Home

Meet PRIMBARBAR’s Portable Carbon Monoxide Detectors for Travel, a 3-in-1 square monitor designed for home safety, RV life, camping, and on-the-go adventures. The new 43-hole design delivers reliable CO detection (0-500 PPM) while also monitoring ambient humidity (0-90% RH) and temperature (32°F to 122°F). A three-segment display keeps readings visually accessible, so you can quickly interpret the current air conditions in any environment.

All-in-one sensing at a glance

This detector emphasizes real-time awareness with a 1-second refresh and a 1.5-inch high-definition display. The color-coded alarm system translates CO levels into intuitive signals: green for safe (0-49 ppm), yellow for a warning (50-99 ppm), and red for danger (100-500 ppm). The device also offers customizable alarm thresholds via simple button actions, so you can tailor alerts to your setting without complicating safety routines.

• 3-in-1 multifunction: CO detection (0-500 PPM) plus humidity (0-90% RH) and temperature (32°F–122°F) in one compact unit
• 43-hole design enhances air sampling and speeds up detection for dependable readings
• 1-second refresh time with a 1.5-inch high-definition display for clear, real-time data
• Color-coded alarms with distinct sounds help distinguish safe, caution, and danger scenarios

Designed for portable use, ready for travel

Powering through trips, the detector offers impressive standby life: up to 120–150 hours on a full charge, with typical use spanning 5–7 days per charge. A full charge takes about 60 minutes, and a low-brightness power-saving mode helps conserve energy when you’re away from power sources. Its compact size (3.15 x 2.76 x 1.18 inches) and light weight (0.22 lb) make it effortless to carry, while a magnetic back lets you attach it to metal surfaces and an outdoor lanyard keeps it accessible on backpacks, tents, or car interiors.

• Ultra-portable and rugged: small footprint with magnetic back for steady mounting
• Includes an outdoor lanyard for easy carrying on backpack, tent, or campsite
• Rich sensing in real-world environments: ideal for camping, travel, vacations, or daily use
• Long standby and quick-charge capabilities reduce the need for frequent recharging during trips

In practical terms, this detector helps you monitor air safety across a range of environments—from a family car to a hotel room to a campsite—without making guarantees, but by offering clear, real-time data and actionable alerts. It’s a versatile companion for travelers who value awareness and convenience in everyday adventures.
