CO Alarm 3-in-1

Carbon Monoxide Alarm 3-in-1 The NESTOUT CO Alarm is a portable carbon monoxide detector built specifically for outdoor environments. It detects CO generated by charcoal, camp stoves, generators, and fuel burning equipment and alerts you before levels become dangerous. Designed to help prevent CO poisoning inside tents, tarps, and vehicles, it pairs reliable detection with built in temperature and humidity readings. Three functions in a single compact unit. The alarm uses a high performance, made in Japan sensor from Figaro Engineering Inc., one of the world leaders in gas sensor production. The sensor is engineered to remain stable across humidity changes and to resist false readings from non-CO gases. A built in self diagnosis function monitors sensor health and alerts you if a fault is detected. IP54 dust and water resistant, backlit LCD, foldable rear stand, and USB-C rechargeable with approximately five days of continuous use per charge. Keep it topped off on longer trips with any NESTOUT power bank or power station. Made in Japan CO Sensor Built around a Figaro Engineering sensor with ±10% accuracy across 0 to 999 ppm. Two tier alerts warn at caution (50 to 99 ppm sustained for 15+ minutes or 100+ ppm) and danger (200+ ppm) levels. Built in compensation for temperature, long term drift, and battery voltage keeps readings accurate as conditions change. Self Diagnosis Function Most CO alarms fail silently. This one runs a self diagnostic at startup and every two hours of continuous operation, alerting you the moment something is wrong with the sensor. Three Sensors, One Device CO detection, temperature (14°F to 122°F), and humidity (20% to 90% RH) in a single unit. Peak CO tracking captures the highest level reached during each detection cycle so you know exactly what happened while you were away from camp. Built for the Outdoors IP54 dust and water resistance. Backlit LCD stays readable in low light. Foldable rear stand for flexible placement on a table, gear shelf, or tent wall. Charge Once, Cover the Trip Approximately five days of continuous operation per charge. USB C charging works with any NESTOUT power station, power bank, or standard charger. Full charge in about 2.5 hours. Placement Matters Always position above head height, near where you sleep or spend the most time. CO rises with warm combustion gases, and a detector placed too low may not alert you quickly enough. Use the foldable stand on an elevated surface or clip the built in hook to a tent ridge or gear loop. Never block the air inlet on the back of the unit. CO ALARM-1 Manual Hereprop 65 warning
