Laser HUNTER - 251220

Variant:

Highly sensitive and selective gas detection & gas measurement device with laser technology for the inspection of underground gas pipes using suitable probes (e. g. carpet probe). The device can also be used for the vehicle-based pipeline inspection. With built-in diaphragm pump, Bluetooth module and rechargeable Li-Ion battery. One out of two different laser modules can be assembled: - single laser module for methane or - dual laser module for methane & ethane Moreover, the device can be equipped with additional sensors to enable further applications. The following applications are possible: - Inspection of underground pipes - Inspection of accessible pipes in buildings - Inspection of accessible pipes on plants, etc. - Inspection of ground soil for pinpointing (optional) - Purging of gas pipelines (optional, only in combination with pinpointing) - Gas analysis (with dual laser module) Operating time up to 10 hours Measurement range depending on built-in sensors Dimensions (LxWxH): 143 x 240 x 85 mm Weight: 2.1 kg Temperature ranges: 0 °C to 40 °C (dual laser module) -10 °C to 50 °C (single laser module)

Description

The Laser HUNTER is a highly sensitive and selective LDAR (leak detection and repair) gas detection device for the systematic pipe network inspection of buried gas pipelines. Due to the innovative laser technology, cross-influences caused by humidity or exhaust gases are excluded. The laser module is available in two variants. In the dual version, the sensor can be used for a quick and uncomplicated differentiation between natural gas or digester gas (ethane analysis) to avoid time-consuming and costly pinpointing in the case of digester gas. If desired, the device can be equipped with additional sensor technology to enable further applications in the course of pipe network inspections. So you have everything in one device!
