Smart Gas Leak Detector: GasNet-S | 4 in 1 WiFi Natural Gas Detector with Real-Time Alerts & Multi-Gas Detection

Smart Gas Leak Detector GasNet-S operates with less than 150mA current, providing real-time WiFi alerts for Coal Gas, Butane, Natural Gas and Biogas leaks. This natural gas detector responds to gas concentrations at 8% LEL, sending alerts within 30 seconds. The WiFi gas detector restores to regular monitoring when gas concentrations return to 0% LEL.

Product Model: Grus

Frequently Asked Questions

Is there an alarm to detect gas?

Yes, GasNet-S gas leak detector is equipped with specialized sensors that can detect various gases such as natural gas and propane, triggering alarms when gas levels reach potentially dangerous concentrations.

Do natural gas detectors really work?

Natural gas detectors are equipped with advanced sensor technologies such as electrochemical sensors, capable of accurately detecting a variety of gases, including but not limited to natural gas and propane, in the early stages of a leak. These highly sensitive sensors can immediately detect elevated gas levels. Upon detecting abnormal gas concentrations, the natural gas detector will promptly alert you through audible alarms and smartphone notifications. This rapid response provides you with a valuable window of time to take necessary precautions to ensure your home's safety.

How does a gas detector alert you?

When the gas detector detects dangerous gas levels, it alerts you with loud alarms and visual signals. GasNet-S can also send notifications to your phone remotely. This means that wherever you are, as long as you have your phone with you, you'll receive immediate alerts.

What type of gases can the Gas Leak Detector identify?

The gas leak detector is triggered by the presence of certain gases in the air that exceed safe levels. Inside the detector, there are specialized sensors, such as electrochemical sensors, that can detect changes in gas concentrations. When sensors detect gas levels above a pre-set threshold, it trigger the alarm system of the detector. This prompt response ensures that you are quickly alerted to any potential gas leaks or hazardous gas levels in your surroundings.

Will the Gas Leak Detector still function during power outages?

Yes, the gas detector comes with a built-in, rechargeable battery that ensures continuous functionality, even during a power outage.

What's the range of the Gas Leak Detector? How many do I need for my house?

The range depends on the size and layout of your home. We recommend at least one detector per floor for optimal coverage.

How quickly does the Gas Leak Detector reset after an alarm?

The detector is designed to reset automatically once the gas concentration drops below the predefined safety levels. The time it takes can vary depending on how quickly the gas dissipates.

How do I reset the device?

Press and hold the reset button for 5 seconds until the device restarts.

What should I do if the device doesn't alarm?

Refer to the user manual for detailed steps on battery replacement.
