7 Year Gas Leak Alarm 100V - 240V Natural Gas Detector For Home

Natural gas and liquefied petroleum gas are widely used in residential properties for cooking, heating and other household applications. While these fuels provide convenience, an unnoticed combustible gas leak can create a serious safety hazard.

The JKD-838 Residential Natural Gas & LPG Leak Alarm is designed to continuously monitor combustible gas in indoor household environments and provide a clear warning when the specified alarm concentration is reached.

Unlike battery-operated gas detectors, the JKD-838 uses a direct AC 100–240V power supply, making it particularly suitable for locations where continuous plug-in operation is preferred. European, American and Australian plug versions are available for different markets.

The detector incorporates a catalytic gas sensor, natural diffusion sampling and combined sound and light warning. With SGS certification and compliance with EN50194-1:2009, the JKD-838 provides distributors, importers and home safety brands with a professionally documented residential gas detection solution.

The home gas alarm market contains many products with similar appearances, so professional buyers need clear reasons to select one model over another.

The JKD-838 focuses on four practical advantages:

Third-party SGS certification provides professional buyers with stronger documentation for product evaluation.

The detector is designed according to the European standard for electrical apparatus used for detecting combustible gases in domestic premises.

One product platform can support customers targeting household natural gas and LPG safety applications.

Different plug configurations make the product easier to adapt for multiple international markets.

Together, these features differentiate the JKD-838 from basic generic home gas leak alarms.

Natural gas consists primarily of methane, making methane detection particularly important in homes using pipeline natural gas.

The JKD-838 can be positioned for buyers searching for a:

• Natural Gas Detector
• Natural Gas Leak Alarm
• Methane Detector
• CH4 Gas Detector
• Methane Gas Alarm
• Home Natural Gas Detector
• Residential Gas Detector
• Combustible Gas Alarm

The specified detection gas is CH4, with an alarm concentration of:

This provides a defined warning point for residential combustible gas monitoring.

The JKD-838 platform is also suitable for LPG detection applications.

LPG is widely used in locations where pipeline natural gas is unavailable, making a reliable LPG gas detector an important product category for home safety distributors.

For LPG-oriented markets, JKD-838 can support product positioning around terms such as:

• LPG Gas Detector
• LPG Leak Alarm
• LPG Gas Sensor
• Home LPG Detector
• Combustible Gas Detector
• Household Gas Alarm
• Flammable Gas Detector
• Residential Gas Leak Detector

This gives distributors greater flexibility when building a home gas safety portfolio for different fuel types.

One of the main characteristics of JKD-838 is its plug-in power design.

The unit operates from:

with maximum power consumption of:

This wide voltage input allows the same basic detector to be adapted for multiple international markets.

Because the product is connected directly to mains power, users do not need to routinely replace batteries as part of the detector's normal power supply.

For permanent residential installations, this makes the JKD-838 a practical AC powered gas detector.

Different countries require different electrical plug configurations. Instead of limiting the detector to one regional market, JKD-838 is available with several plug versions.

Suitable for relevant European markets and particularly useful for European distributors sourcing EN50194 residential safety products.

Available for markets using the corresponding American plug configuration.

Available for Australia and other compatible markets.

For international importers, this provides a significant sourcing advantage: the same plug-in gas alarm platform can be adapted to different sales regions without developing a completely separate product.

The JKD-838 uses a catalytic gas sensor for combustible gas detection.

The detector works through natural diffusion. Surrounding air enters the sensing area naturally, allowing the catalytic sensor to continuously monitor for the target combustible gas.

This design eliminates the need for an external sampling pump and is well suited to residential gas detection.

The maximum specified sensor lifetime is:

For distributors, this provides a clearly defined product service period for sales materials and after-sales planning.

Detecting gas is only part of the job. A residential gas warning device must also alert occupants clearly.

JKD-838 provides:

• Audible alarm
• Light alarm indication

The sound level reaches:

The combination of sound and visual indication gives users a clear warning when the detector enters the alarm state.

The JKD-838 is an indoor-use residential gas detector.

Its specified operating environment includes:

Temperature: -10°C to +50°C
Relative Humidity: ≤95%, non-condensing
Atmospheric Pressure: 86kPa–106kPa

These parameters allow the detector to operate across a broad range of normal indoor residential conditions.

Typical applications include:

• Home kitchens
• Apartments
• Houses
• Residential buildings
• Rental properties
• Holiday homes
• Properties using natural gas
• Properties using LPG

Actual installation position should always follow the user manual and requirements for the target gas.

Residential safety equipment should provide dependable protection without being unnecessarily bulky.

The JKD-838 measures:

and weighs approximately:

Its compact housing makes the detector suitable for household environments while accommodating the AC power system, catalytic sensor and audible/visual warning components.

European distributors often place certification and applicable standards among their first considerations when evaluating a new combustible gas detector.

JKD-838 is manufactured according to:

and is supported by:

For B2B customers, this can provide several advantages:

• Clear technical basis for product evaluation
• Recognized third-party testing support
• More professional product documentation
• Better fit for European residential safety portfolios
• Greater confidence for distributors and importers
• Stronger sales positioning than uncertified generic products

For this reason, SGS and EN50194 should remain prominent selling points in JKD-838 marketing materials.

JKD-838 is developed not only for end users but also for professional B2B sourcing.

Potential customers include:

• Fire safety distributors
• Gas safety distributors
• Electrical wholesalers
• Home improvement retailers
• DIY chains
• Security product distributors
