Product Description

Intrinsically Safe Laser Distance Meter/ Underground Pipe Gas Leak Detector



LT-828 Underground Pipe Gas Leak Detector is an ideal instrument for pinpointing underground pipeline gas leaks, such as Natural gas, liquefied petroleum gas (LPG), artificial coal gas and so on. It can measure combustible gas, CO, O2, H2S. LT-828 is widely used in the department of town gas, petrochemical, oil depot, oil and gas field and so on.



LT-828 Underground Pipe Gas Leak Detector is characterized by high sensitivity and good selectivity. You needn’t drill, you can detect the buried pipeline and leak point directly.

Battery: high capacity lithium battery, intelligent charging quickly, without human control, saving the cost

Sensor and the air pump: The most advanced one in the world

anti-interference, low temperature resistant, high stability.

Voice Alerts:

It changes according to gas concentration. You needn’t observe display. Then work efficiency has been improved.

The gases from dozens of meters could be inhaled into the included getter pump instrument and then detected.

It has a self-inspection to display, battery, sensor and acousto-optic alarm function while started or needed.
