Portable flammable gas detector alarm with semiconductor sensor for natural gas, methane, biogas detection measuring 160x66x31mm with adjustable sensitivity and LED visual alarm
AS8800L Portable Flammable Gas Detector with Semiconductor Sensor and LED Alarm

The AS8800L portable flammable gas detector provides practical gas monitoring for environments where natural gas, biogas, or methane may be present. This compact detection device measures 160mm x 66mm x 31mm and uses a semiconductor sensor to identify gas concentrations as low as ≤5PPM. With both visual LED alarms and analog row light indicators, the unit gives clear warning signals when flammable gases reach detectable levels. The detector operates on three AA alkaline batteries, delivering approximately four hours of continuous monitoring capability in temperature conditions ranging from 0 to 52°C.
Features and Construction

This gas detection unit combines practical monitoring features with straightforward operation. The compact portable design makes it suitable for various locations where gas monitoring may be required.
Material and Build
The AS8800L detector incorporates a semiconductor sensor element specifically designed to detect flammable gases. The housing contains the electronic components and battery compartment arranged within its 160mm x 66mm x 31mm dimensions. This construction allows the unit to be carried or placed in locations where gas monitoring is needed, with physical controls for sensitivity adjustment and operational settings.
Size and Practical Fit
Measuring 160mm in length, 66mm in width, and 31mm in depth, the detector maintains a compact footprint suitable for placement on surfaces or carrying in appropriate cases. The dimensions allow the unit to be positioned in various monitoring locations while remaining portable enough to move between areas. The specific measurements ensure the detector can be accommodated in spaces where gas monitoring equipment is required.
Uses and Placement

The detector serves multiple practical applications where flammable gas monitoring provides safety benefits. Its portable nature allows flexibility in deployment.
Event or Professional Use
For professional settings, the AS8800L can monitor areas where natural gas, biogas, or methane systems are installed or in use. The semiconductor sensor detects these flammable gases with ≤5PPM sensitivity, providing early indication of potential leaks. The four-hour continuous operation on AA batteries allows monitoring during work periods, while the 0-52°C operating range suits various indoor environments. Visual LED alarms and analog row lights give clear indication without relying solely on auditory signals.
Everyday Home Use
In residential settings, the detector can monitor areas where natural gas appliances are installed. The portable design allows positioning near gas lines, water heaters, or cooking appliances. Warm-up time under 110 seconds at standard conditions means the unit can provide monitoring relatively quickly after activation. The low battery reminder function alerts users when the three AA alkaline batteries require replacement, helping maintain consistent monitoring capability.
Benefits and Buying Value

The AS8800L detector offers practical monitoring features focused on gas detection functionality rather than complex interfaces.
Reuse and Low Maintenance
With replaceable AA batteries and no specified consumable sensor elements requiring regular replacement, the detector maintains operation through battery changes. The semiconductor sensor provides gas detection without complex calibration requirements mentioned in the source material. External power supply capability offers flexibility in power source selection, potentially extending monitoring duration beyond the four-hour battery operation when connected to appropriate power.
Why Choose This Product
The AS8800L detector provides specific flammable gas monitoring for natural gas, biogas, and methane with measurable ≤5PPM sensitivity. Its compact 160x66x31mm dimensions suit portable use while the visual LED and row light alarms give clear gas presence indication. The adjustable sensitivity allows matching detection levels to specific monitoring needs, and the 0-52°C operating range accommodates various indoor environments. For those requiring portable gas detection with visual indicators and adjustable settings, this unit offers focused monitoring capability.
