AS8800L portable flammable gas detector alarm for natural gas, biogas and methane leak detection with adjustable sensitivity and low battery reminder, powered by 3 AA alkaline batteries, measuring 160mm x 66mm x 31mm
AS8800L Portable Flammable Gas Leak Detector with Adjustable Sensitivity

This portable gas detector is engineered for identifying leaks of combustible gases including natural gas, town gas, and biogas. It serves as a practical tool for safety checks in various settings where such gases may be present. The AS8800L model offers a specific sensitivity level, capable of detecting gas concentrations as low as 5 parts per million, and includes visual indicators to alert the user.
Features and Construction

The detector incorporates a semiconductor sensor type, which responds to the presence of specified flammable gases. Its design prioritises portability and straightforward operation, with clear visual prompts provided through an LED light system.
Material and Build
The device is built for handheld use, featuring a housing that facilitates its portable function. The construction incorporates the necessary electronics for the semiconductor sensor, power management for the battery supply, and the LED display for the alarm and analog prompt system.
Size and Practical Fit
With dimensions of 160 millimetres in length, 66 millimetres in width, and a depth of 31 millimetres, the detector is compact and easy to handle. This size makes it suitable for carrying to different locations for spot checks or for use in confined spaces where a permanent fixed detector might not be installed.
Uses and Placement

The primary application is gas measurement for safety purposes. It is used to check for leaks from appliances, pipes, or in areas where biogas might accumulate, providing an immediate visual indication of gas levels.
Event or Professional Use
For professionals in maintenance, installation, or safety inspection roles, this detector provides a specific tool for verifying there are no dangerous gas leaks after work on gas systems or in new installations. Its portable nature allows it to be part of a toolkit for on-site visits.
Everyday Home Use
Homeowners can use this device for periodic safety checks around gas boilers, cookers, or heaters. The simple alarm system via LED lights offers a clear, immediate warning without complex interfaces, making it accessible for general household safety monitoring.
Benefits and Buying Value

The value of this product lies in its defined function as a dedicated leak detector for specific flammable gases. It provides a measured response with its adjustable sensitivity, allowing the user to set the alarm threshold according to their requirements.
Reuse and Low Maintenance
The detector is designed for repeated use, powered by standard AA alkaline batteries which are widely available. The inclusion of a low battery reminder function helps ensure the device remains operational when needed, and the stated four-hour continuous working time provides a clear expectation for battery life per set.
Why Choose This Product
Choosing the AS8800L is based on its concrete specifications: its detection capability for common flammable gases, its portable form factor, and its self-contained power system. It offers a focused solution for gas leak detection without unnecessary additional features, aligning its operation with the stated sensitivity and environmental operating range.
