When distributors and safety brands source a combustible gas detector, price and appearance are only part of the purchasing decision. For professional residential safety markets, applicable standards, third-party testing, sensor technology and stable manufacturing are equally important.
The JKD-838 EN50194 Combustible Gas Detector is developed for indoor residential gas monitoring and is suitable for natural gas and LPG applications. It combines a catalytic sensing system with AC-powered continuous operation, audible and visual warnings and a five-year maximum sensor lifetime.
For European buyers, one of its strongest advantages is compliance with EN50194-1:2009, supported by SGS certification.
The detector operates from AC 100–240V, 50Hz, with European, US and Australian plug versions available. This gives importers and private-label brands a flexible residential gas alarm platform that can be adapted to different international markets.
When sourcing a home gas detector for the European market, professional buyers frequently look beyond basic specifications and evaluate the applicable product standard.
The JKD-838 is manufactured according to:
and supported by:
This is a major selling point for distributors that require documented products rather than generic gas leak alarms with limited compliance support.
For professional buyers, the certification package helps with:
For this reason, the JKD-838 is particularly suitable for customers searching for an EN50194 gas detector or SGS certified gas alarm.
Natural gas is widely used in residential properties for cooking and heating.
Since methane (CH4) is the principal component of natural gas, methane detection is an important part of residential natural gas safety.
The specified detection gas of JKD-838 is:
This allows the detector to be positioned in the market under several relevant product terms:
This broader terminology is also valuable for SEO because professional buyers do not always use the same search phrase when sourcing the same type of product.
The JKD-838 platform can also be supplied for LPG detection applications.
LPG is commonly used in residential environments where bottled or tank-supplied gas is preferred. For distributors serving these markets, an LPG gas detector is an important addition to a complete home safety portfolio.
Relevant product positioning can include:
The ability to address both natural gas and LPG applications makes JKD-838 more flexible for international distributors.
The sensing element is at the heart of every reliable gas leakage detector.
JKD-838 uses a:
Catalytic sensing technology is designed for combustible gas monitoring and provides a practical solution for residential applications.
The detector uses:
Surrounding air reaches the sensor naturally without an external sampling pump. The sensor continuously monitors the environment and triggers the alarm system when the defined gas concentration is reached.
This simple detection architecture supports stable continuous operation for household applications.
JKD-838 has a specified alarm concentration of:
LEL refers to the Lower Explosive Limit, an important measurement used when describing combustible gas concentrations.
When the target gas reaches the specified alarm condition, the detector activates its audible and visual warning.
For professional buyers, clearly defined LEL performance is an important parameter when comparing different flammable gas detectors and residential gas sensors.
Unlike the lithium battery models in the product range, JKD-838 is designed for continuous mains-powered operation.
This makes the JKD-838 a practical plug-in gas detector for permanent residential installations.
Advantages of AC operation include:
For customers who specifically prefer battery-powered gas detection, separate lithium battery models are available, while JKD-838 serves the traditional AC-powered segment.
International distributors often sell into markets with different plug systems.
The JKD-838 can be supplied with:
Combined with its AC 100–240V input, these options make it easier for B2B customers to adapt the same product platform for different regions.
This is particularly useful for private-label brands selling safety products across multiple markets.
An effective gas safety alarm must provide a clear warning once an alarm condition occurs.
The JKD-838 provides:
with an alarm volume of:
The audible warning is supported by visual alarm indication, helping users quickly recognize the detector's alarm status.
This combination provides a straightforward warning method for residential users.
The catalytic sensor has a specified maximum lifetime of:
For distributors and private-label brands, a defined sensor lifetime provides useful information for:
The five-year sensor specification also provides a clear distinction between the sensor service life and the detector's everyday AC power supply.
The JKD-838 is an indoor-use gas detection device.
Its specified operating environment includes:
| Environmental Parameter | Specification |
|---|---|
| Operating Temperature | -10°C to +50°C |
| Relative Humidity | ≤95%, Non-condensing |
| Atmospheric Pressure | 86kPa–106kPa |
| Application Type | Indoor Use |
Potential residential applications include:
Detector placement should follow the user manual and the requirements of the target gas.
The JKD-838 measures:
with a weight of approximately:
The housing integrates the gas sensing system, AC power components and audible/visual warning functions into a compact residential unit.
For distributors, the compact size also helps simplify retail packaging and transportation.
Many professional safety distributors already sell smoke detectors and carbon monoxide alarms. Adding a combustible gas detector allows them to provide a more complete household safety portfolio.
The JKD-838 can complement product categories such as:
This makes it suitable for established safety distributors as well as brands expanding into residential gas detection.
The JKD-838 is designed for professional sourcing and can serve customers including:
For these buyers, the strongest purchasing combination is:
This creates a clear product story that is easy for distributors to communicate to their own customers.
We support international customers with flexible OEM, ODM and private-label manufacturing.
Customization options include:
This allows professional buyers to build a gas safety product that matches their own brand and target market.
For a detector designed to continuously monitor combustible gases, consistent manufacturing is essential.
Quality control procedures for the JKD-838 include:
These procedures help maintain consistent quality across repeat production orders.
