Protmex 4-in-1 CO and Gas Detector with Large LCD – Plug-in, Temperature and Humidity Monitoring

Overview

The Protmex 4-in-1 CO and gas detector combines essential sensing with climate data in a single plug-in device. Designed for homes and travel alike, it sits neatly in a standard outlet and shows key readings on its large display, making it easy to keep an eye on environmental conditions without clutter.

What it monitors

This detector provides CO detection, gas leak sensing, plus real-time temperature and humidity readings. It uses dual sensors to respond quickly and sends both audible and visual alerts when readings reach the defined thresholds (CO at 50 ppm or gas at 5% LEL).

Clear, at-a-glance readings

The 2.0-inch display presents current values in a legible format, enabling you to understand the room conditions from across the room rather than peering at tiny indicators.

Plug-and-play convenience

Installation is straightforward: plug into any 110V-220V outlet. No wiring, no batteries, and no tools are required. This makes it suitable for kitchens, bedrooms, RVs, and hotel rooms, providing quick reassurance wherever you are.

Practical benefits at a glance

• 4-in-1 protection: CO, gas, temperature, and humidity in one compact device
• Immediate alerts with a loud 85 dB alarm and a flashing visual indicator at threshold
• Large display for easy monitoring from a distance
• Versatile placement for home, travel, or temporary stays

Real-world use cases

Place it in areas with gas appliances, near sleeping zones for overnight awareness, or in RVs and hotel rooms during trips. The device continuously displays readings so you can respond promptly if needed.

Important notes

While it provides early warning signals, this is not a medical device. Regular checks and proper placement help maintain awareness in living spaces.

With Protmex, you gain a practical 4-in-1 system that combines protection with actionable data, offering possibilities for safer, more informed environments.
