WN-608 push-type gas pipeline leak detector design novel, functional integration. All components concentrated in the cart, using large-scale integrated circuits, LCD display, sound and light alarm, power undervoltage alarm function; Air pump, with anti-interference, low temperature resistance, high sensitivity, without drilling, direct ground detection of buried pipes and leaks; alarm sound with the gas concentration changes, the operator without observing the display part, improve work efficiency. Instruments are widely used in urban gas, oil, petrochemical, oil depots, gas stations, oil fields and other sectors of the gas pipeline safety inspection and pipeline maintenance and leakage rescue, is essential to China's 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
