High-Precision Sensor & Instant Response:

The AGT-2309 carbon monoxide detector accurately monitors CO levels from 0 to 1000 PPM. Equipped with a advanced high-sensitivity sensor, it responds in as fast as 0.3 seconds, providing real-time air quality tracking to keep your living space and family protected.

Ultra-Long 15-Day Battery Life & Fast Charging:

Engineered for low power consumption, this handheld CO monitor delivers up to 15 days (360 hours) of continuous operation on a single charge. Recharge easily via the included Type-C cable—no need to buy or replace disposable batteries during home use or long camping trips.

Versatile Portable Design with Stand & Lanyard:

Ultra-compact and lightweight, the AGT-2309 comes with both a foldable desktop stand and a durable lanyard. Position it upright on nightstands, countertops, and office desks, or hang it inside tents and RVs for versatile placement wherever you go.

Intuitive Breathing Light Alerts & Simple Operation:

Features clear, color-coded visual and audible alerts. In standby mode, a gentle green breathing light confirms safe operation. When CO reaches danger thresholds, the light turns red, a flame icon appears, and a loud alarm sounds. Simple 3-button controls ensure zero learning curve.

How to test AGT-2309 before use?

1.Lighted cigarette: Place the detector near cigarette smoke.

2.Smoldering paper: Light a piece of paper, extinguish the flame, and let it smolder. Place the detector and smoldering paper in a sealed, non-flammable container (such as a glass jar).

Why does the screen dim? Is my device still working?

This is for power saving, you can customize or disable the screen timeout in the menu. The device still works normally even when the screen dims. Press any button to wake up the screen.

Why does the device sometimes fail to detect CO?

Not all combustion generates enough carbon monoxide to trigger detection. In well-ventilated areas or during complete combustion (e.g., a gas stove’s blue flame or a car engine running smoothly), CO levels may be too low for the detector to activate.

What is the difference between Carbon Monoxide (CO) and Carbon Dioxide (CO₂)?

Carbon monoxide (CO) is from incomplete combustion, a colorless, odorless, tasteless toxic gas. Carbon dioxide (CO₂) is mainly from biological respiration, a non-toxic gas common in nature and part of the carbon cycle.
