Simple CO ppm display with LED and sound alarms. 🏇 FAST ALARM: alarm at > 9 ppm after 60 secs, compared to home CO detectors that alarm > 70 ppm in 60 - 240 minutes. Red LED and buzzer alarms at 9 ppm / 25 ppm. 🕵️ TRUSTWORTHY: ** 1-year limited warranty ** Product tested and verified in the USA ** 100% quality guaranteed ** Details: A small and elegant travel CO detector with high-quality Japanese sensor technology for MAX personal protection. Designed with strong aluminum and a stylish metal finish. Early alarming at 9 ppm to prevent CO exposure that commonly triggers headaches, nausea, and fatigue. CO alarms are set at 9 ppm with red LED & 25 ppm with an audible buzzer sound (70 dB). The 9 ppm alarm level was chosen as recommended by the World Health Organization (WHO), Environmental Protection Agency (EPA), American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), and American Conference of Governmental Industrial Hygienists (ACGIH). The detector includes smart detection algorithms designed in California and a high-quality CO electrochemical sensor made in Japan. Regular CO alarms are too slow, alarming in 60 to 240 minutes when over 70 ppm - exceeds recommended exposure limits. One-button operation makes it easy for anybody to operate.
