WN-618 push-type gas pipeline leak detector design novel, functional integration. All components concentrated in the trolley, the use of large-size integrated circuits, LCD display, sound and light alarm, power undervoltage alarm function; use high-quality sensors and Air pump, with anti-interference, low temperature resistance, high sensitivity, no drilling, direct ground detection of buried pipes and leaks; alarm sound changes with the gas concentration changes, the operator did not need to observe the display part, improve work efficiency. The instrument is widely used in urban gas, oil, petrochemical, oil depots, gas stations, oil and other sectors of the gas pipeline pipeline safety inspection and pipeline maintenance and leakage rescue, is essential for our gas industry leak detection equipment.

'Detection principle and method'
When the air containing combustible gas, sent to the sensor through the air pump, the detection component of the resistance will quickly become larger (the resistance changes with the size of the gas is proportional to the concentration), while a voltage signal output, amplified by the circuit to Display part, and generate alarm signal
