SL-908A, B hand-push gas pipeline detector for the trolley-type detector, detection does not require drilling and dug casing, just push the instrument above the gas pipeline to walk, you can directly detect the underground gas pipeline on the ground The instrument is widely used in urban gas, oil, petrochemical, oil depots, gas stations, oil and gas fields and other departments of the gas pipeline safety inspection and pipeline maintenance and leakage rescue and so on.It is widely used in the field of underground gas pipeline leak detection. When the air containing combustible gas, sent to the sensor through the air pump, the detection element of the resistance will rapidly become large (the size of the resistance changes with the gas concentration is proportional to), while a voltage signal output, the circuit amplified to Display part, and generate alarm signal.

'Features'
● New design, functional integration, all components concentrated in the cart, with light weight, easy to operate, greatly reducing the labor intensity;
● high-capacity nickel-metal hydride batteries, fast smart charging, no manual control, saving the use of cost;
● The use of the world's most advanced sensors and air pumps, with anti-interference, low temperature and high stability characteristics;
● use of large-scale integrated circuits, digital display, sound and light alarm, power supply under pressure and gas blockage alarm;
● high sensitivity, good selectivity, without drilling, direct ground detection of buried pipelines and leaks;
● alarm sound with the gas concentration changes, the operator does not need to observe the display part, improve work efficiency.
