Hand push gas pipeline detector
HQ-H1 Hand Push Gas Pipeline Detector
Product details

Detailed introduction:
This product has a novel design and integrated functionality. Characterized by light weight and easy operation; Adopting lithium-ion batteries for fast and intelligent charging; Adopting large-scale integrated circuits, LCD display, sound alarm, and power undervoltage alarm functions; Imported sensors and air pumps are selected, which have anti-interference, low temperature resistance, stability, high sensitivity, good selectivity, and do not require drilling. They can directly detect the leakage points of buried pipelines on the ground; The alarm sound changes with the gas concentration, and the operator does not need to observe the display part, which improves work efficiency.

2. Detection principle
When corrosive perforation and fracture occur in underground gas pipelines, trace gas leaks will inevitably occur and slowly spread in surface ditches, wells, sewers, and other places. When the leak detector sends air containing flammable gases to the sensor through an air pump, the resistance value of the detection element will rapidly change with the gas concentration (the magnitude of the resistance value change is proportional to the gas concentration), and at the same time, output a voltage signal, which is amplified by the circuit and processed by the microcontroller before being sent to the display part, and generate an alarm signal that changes with the concentration.
