- 【4-in-1 Gas and Carbon Monoxide Detector 2 pack】This multi-functional CO detector can monitor natural gas (0–10000 PPM, methane), carbon monoxide (CO, 0-999PPM), temperature (11–125°F), and humidity (5%–95% RH) data in real time—ideal for kitchens, bedrooms, RVs, outdoors, and offices, providing comprehensive protection for you and your family.
- 【Dual-Sensor Design – Fast and Accurate Alerts】Equipped with both an electrochemical CO sensor and a catalytic gas sensor, the carbon monoxide detector for cars updates readings every 2 seconds. When carbon monoxide (≥51 PPM) or natural gas (≥600 PPM) reaches dangerous levels, a loud 85 dB alarm sounds along with a bright flashing red light. The audible and visual alerts help you detect hazards quickly, take timely action, and prevent potential safety risks.
