4-in-1 Carbon Monoxide & Natural Gas Leak Detector
Merchant VideoThe Kalawen 4-in-1 Plug-In Detector integrates cutting-edge technology to monitor combustible gases, carbon monoxide (CO), temperature and humidity in one compact unit.

Its comprehensive gas detection capabilities cover hazardous gases such as carbon monoxide, natural gas, propane, methane, gas, alcohol, gasoline, hexane, butane, benzene, ethylene oxide, acetylene, LPG, LNG and more.

180° rotatable high-definition LCD display provides instant access to key data, including real-time carbon monoxide readings (0-999PPM ±10%), combustible gas progress bar (GAS Lv1-4: 0-15% LEL), humidity levels (0-95%) RH ±5%) and dual scale temperature measurement (-10°C to 50°C / 14°F to 122°F).

For optimal performance, remove the protective film before plugging in and allow 180 seconds for initial calibration. Please note that humidity and temperature readings will be more accurate after a 30-minute warm-up period, as the unit may heat up during startup.
Technical Specifications
Can it detect other gases besides co and natural gas?
Detected gases include: CO, natural gas, propane, methane, town gas, alcohol, gasoline, hexane, butane, benzene, ethylene oxide, acetylene, LPG, LNG, and more.
Why do I need to remove the protective film and warm up the detector for 180 seconds before using it?
Removing the protective film ensures a clearer digital display. Preheating ensures that the detector works properly and accurately.
How loud is the alarm? Can it be plugged into any outlet?
= 85 DB sound when alarming. Compatible with all U.S. standard 110V-220V AC outlets with standby power consumption as low as = 2W.
What should I do in case of a detector alarm?
Confirm the gas leak source, avoid electrical devices and flames, and ventilate the area. If it's a natural gas leak, shut off the gas. For a high carbon monoxide alarm, evacuate immediately and call emergency services.
Does it meet any safety certification standards?
The Kalawen 4-in-1 detector meets UL safety certification standards for simultaneous detection of natural gas and carbon monoxide and combustible gases. High sensitivity and dual sensors keep you and your family safe.
