Battery Powered Gas Leak Alarm Long Life Combustible Gas Leak Detector

For households using natural gas or LPG, continuous gas monitoring can provide an important additional layer of safety. A plug-in gas leak detector offers a practical advantage for permanent residential installation: once connected to the mains supply, the unit can continuously monitor the surrounding environment without routine battery replacement.

The JKD-838 is an AC-powered combustible gas detector developed for residential natural gas and LPG applications. It operates from AC 100–240V, 50Hz, uses a reliable catalytic gas sensor, and provides both audible and visual warnings when the specified gas concentration reaches the alarm threshold.

For professional buyers, the JKD-838 offers another important advantage: it is manufactured according to EN50194-1:2009 and supported by SGS certification.

With European, American and Australian plug options available, this home gas leak detector provides distributors, importers and private-label brands with one flexible platform for different international markets.

For fixed residential applications, a plug-in gas detector provides straightforward operation and continuous power.

There is no need for complicated hardwiring, and users do not need to periodically replace batteries as part of normal power-supply maintenance.

Key benefits include:

• Continuous AC-powered operation
• No routine battery replacement
• Simple plug-in installation
• AC 100–240V wide voltage input
• EU plug available
• US plug available
• AU plug available
• Low power consumption
• Continuous combustible gas monitoring
• Suitable for residential indoor use

For distributors selling home safety products, an AC powered gas alarm is a familiar and practical solution for customers using household gas appliances.

Different homes and markets rely on different fuel gases.

Natural gas is widely used through municipal pipeline systems, while LPG is frequently supplied through cylinders or tanks. This creates demand for gas safety products that can serve different residential applications.

The JKD-838 platform is suitable for natural gas and LPG detection applications, allowing it to be positioned as a:

• Natural Gas Detector
• LPG Gas Detector
• Methane Detector
• CH4 Detector
• Combustible Gas Alarm
• Flammable Gas Detector
• Residential Gas Leak Detector
• Household Gas Alarm

For importers supplying multiple markets, this flexibility can simplify product portfolio planning.

The sensing technology is one of the most important components of a gas leakage detector.

JKD-838 incorporates a catalytic sensor designed for combustible gas detection. The detector uses natural diffusion sampling, meaning surrounding air naturally reaches the sensing element without the need for an external pump.

The specified alarm concentration is:

When the detected gas concentration reaches the defined alarm level, the unit activates its audible and visual warning.

The maximum sensor lifetime is 5 years, providing a practical service period for residential applications.

A gas safety alarm needs to provide an obvious warning that occupants can quickly recognize.

The JKD-838 combines:

Sound Alarm + Light Alarm

with an audible output of:

This dual warning method provides both an audible alert and visual indication when an alarm condition occurs.

For everyday operation, the design is simple and straightforward, making the product suitable for household users without specialist technical knowledge.

Certification is particularly important for distributors sourcing residential safety products for Europe.

The JKD-838 is supported by SGS certification and manufactured according to:

For distributors, wholesalers and brand owners, this provides a stronger foundation for technical evaluation compared with generic gas leak alarms without recognized third-party certification.

Key compliance advantages include:

• SGS certification
• EN50194-1:2009 standard
• Professional technical documentation
• Suitable positioning for European residential markets
• Easier internal product evaluation for professional buyers

This makes certification one of the strongest selling points of the JKD-838.

The JKD-838 is developed for indoor residential applications where combustible gases are used.

Potential applications include:

• Home kitchens
• Apartments
• Residential houses
• Rental properties
• Holiday homes
• Residential buildings
• Indoor natural gas applications
• Indoor LPG applications

Its compact dimensions of 120 * 75 * 40mm allow the detector to integrate easily into residential environments without occupying excessive space.

At approximately 200g, the unit remains compact while incorporating the catalytic sensing system, alarm electronics and integrated AC power design.

International distributors often need different electrical plug versions for different markets.

JKD-838 can be supplied with:

Suitable for customers targeting relevant European markets.

Available for markets using the corresponding plug format.

Available for Australia and other compatible markets.

Combined with the AC 100–240V input range, these plug options make the JKD-838 a flexible residential gas detector for international distribution.

The JKD-838 is suitable not only as a finished product but also as a platform for B2B customers building their own home safety ranges.
