China Manufacturer Wall Mounted Combustible Gas Leak Detector and Sensor
>>>Product Description
K500 series wall mount gas detector provides effective protection against gas leakage by offering real-time concentration monitoring and immediate on-site alarm. Once gas concentration exceeds preset alarm levels, the detector activates a bright flashing light and a loud 90dB audible alarm to alert personnel instantly.
The rugged aluminum alloy housing ensures resistance to dust, moisture and harsh industrial conditions. High sensitivity sensors enable fast response time and reliable performance for toxic and combustible gas detection.
This detector is widely applied in factories, boiler rooms, warehouses and enclosed spaces where early warning and local alarm are essential for personnel safety.
