Introduction2

HS4000 is an ultralight and highly sensitive instrument that utilizes infrared laser to remotely detect methane leaks. HS4000 comes with
Bluetooth capability that can transfer measurement data in real-time to the dedicated APP. Users can use the APP to check, record and
export the data. Through the APP, users can generate detection reports using the saved data as well.

2.1

Working Principle

HS4000 emits an infrared laser at 1.65 um. The laser beam travels to the target, is partially absorbed by the gas, then reflected all the way
back into the receiver.
The reflected laser is collected and converted to an electrical signal that carries information needed to deduce the relative methane concentration.
The reading is expressed by a methane column density (ppm*m). It is the integral of the methane concentration (ppm) and the distance (m)
on the optical path.
