YOJOCK 4-in-1 Gas & CO Detector – Plug-In Portable with Temperature and Humidity Display

Compact 4-in-1 Gas and CO Detector for Home, Hotels, and Travel

The YOJOCK Gas and CO Detector is a compact plug-in device that combines carbon monoxide monitoring, combustible gas sensing, and real time environmental readings. Its unobtrusive profile fits on a shelf, bedside table, hotel dresser, or RV dash, delivering ongoing awareness of air conditions without clutter.

What it detects

• Carbon monoxide and common combustible gases such as propane, natural gas, methane, LPG, and butane
• Ambient temperature and humidity for quick room condition checks

With this combination, you have a single tool that helps you observe both gas levels and the environment where you spend time. It does not replace professional assessment, but it can support safer routines and informed decisions.

Performance and alerts

• Advanced electrochemical sensors for CO and catalytic sensors for gas detection provide fast, reliable readings
• CO range 0 to 2000 PPM and gas detection up to 10 percent LEL
• Response times are designed to help you assess conditions quickly

When readings rise, a loud alarm and a flashing red light activate to signal you to check the space. The 85 dB audio alert remains audible even in busy rooms, kitchens, or hotel corridors.

Portability and efficiency

• Travel-friendly size at 1.93 by 2.05 by 4.69 inches and about 0.18 lb, easy to stash in a bag
• Low power consumption at ≤2 W, costing roughly 0.17 per month to operate
• Plug-in convenience that does not rely on batteries for continuous protection

Its compact form makes it suitable for home, office, hotel, or travel setups, giving you flexibility without sacrificing safety features. The included instruction manual and a 3-year warranty add to peace of mind.

Real-world usage and support

Use it on a kitchen counter, bedside table, hotel room dresser, or RV dashboard to monitor CO, gas, and ambient conditions during daily routines or trips. If you need help, our responsive team is ready to assist within 24 hours.
