C601 Portable CO Meter – Clear carbon monoxide monitoring, anywhere Carbon monoxide (CO) is dangerous precisely because it’s hard to notice: it’s invisible, odorless, and symptoms can be vague. The C601 portable CO meter helps you monitor CO levels (ppm) in real time, so you can respond based on data rather than guesswork. It also shows temperature and humidity, with a bright display that remains easy to read in low light. Reliable monitoring comes from timely data A single reading is useful, but what matters most is how levels behave over time. The C601 refreshes measurements frequently and combines visual, sound, and vibration alerts to get your attention when it matters—without requiring an app, account, or registration. That simplicity supports clearer decisions, especially in changing environments. Key features and benefits Measures carbon monoxide (CO) from 0–2000 ppm with 1 ppm resolution. Updates readings every 2 seconds for timely awareness. Adjustable alarm values (three levels), with factory options including 41 ppm / 75 ppm / 100 ppm. Multi-alert system: sound vibration warning lights for clear signaling. Displays CO, temperature, and humidity on one screen. Long standby time after a full charge for practical everyday use. USB-C charging for convenience and compatibility. Compact and portable (59 × 59 × 18.9 mm, approx. 74 g) with a lanyard option. How to use it in a way that’s actually trustworthy Use the device where airflow is representative of what you’re breathing—and don’t block the air inlet. After moving between rooms or environments, allow a short moment for readings to stabilize. If you set custom alarm values, choose thresholds that match your intended use and environment. For calibration, follow the instructions and calibrate only in fresh air when appropriate. Important note on safety A portable CO meter is a smart layer of awareness, but it doesn’t replace certified, permanently installed carbon monoxide alarms where those are recommended or required. If the device alarms or you suspect CO exposure, ventilate the area and follow local safety guidance. What’s included C601 portable CO meter USB-C cable Lanyard User manual
