GASDOC DS-399

The GasDoc DS-399 is a portable carbon monoxide detector that can detect carbon monoxide concentrations from 0 to 1000PPM, while also monitoring the temperature and humidity of the environment.This carbon monoxide detector features convenient Type-C charging, eliminating the need for batteries. A single charge powers it for up to 7 days of continuous use, making it perfect for everyday monitoring and on-the-go reliability.

How to Test if the Carbon Monoxide Detector is Working:

Carbon monoxide is typically produced during incomplete combustion and in smoky environments. Here are two simple testing methods:
Using a Lit Cigarette: Light a cigarette and hold the DS-399 detector's sensor near the smoke. When the device displays a reading or triggers an audible and visual alarm, it indicates that the carbon monoxide detector is functioning.
Controlled Smoke Environment: Light a small stick or piece of paper, and use a transparent cover to enclose both the burning item and the detector in a sealed space. When the device shows a reading or triggers an audible and visual alarm, it confirms that the detector is working.

Long Battery Life:

The DS-399 carbon monoxide detector is equipped with a powerful 1000mAh lithium battery, offering up to 168 hours of continuous use on a full charge. It also features Type-C charging for minimal downtime.

With both visual and audible alarms, the DS-399 ensures quick response and timely alerts to protect your safety.
Green: 0–50 ppm (Low concentration)
Yellow: 51–150 ppm (Dangerous concentration)
Red: Above 150 ppm (Alert concentration)

Customizable Alarm Threshold:
