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, wireless data transfer 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: - Testing of underground pipes - Testing of exposed pipes in buildings or outdoors - Testing of soil air for localisation (optional) - Purging of gas pipes (optional, only in combination with soil air testing) - Quantification in underground or above-ground installations (optional) - Recording of methane peaks (optional) - Gas analysis (with dual laser module) Operating time: up to 10 hours Measurement range: depending on built-invsensors 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!

Laser HUNTER at the core of a modular system for every application

The Laser HUNTER can be used as the core of our modular system for pre-location.

The Laser HUNTER is the central element of the modular system for above-ground leak detection and gas concentration measurement. Since the revision of the DVGW regulation G 465-1 in 2019, various forms of above-ground inspection have been approved. The modular design offers the right solution for every application – flexibly combinable with just one Laser HUNTER as the detection device.

Depending on the terrain and requirements, different carrier systems are used:

from the classic carpet probe (TS14) or bell probe for manual inspection, to the e-scooter with carpet probe for urban routes, to the quad bike with suction bar and pump unit for rough terrain. The GasCar Laser HUNTER is available for efficiently testing large areas in accordance with DVGW G 465-1 – a vehicle-based solution with an integrated suction system.

Thanks to the modular system, the detection performance remains constant, regardless of the vehicle system – thus enabling seamless and standard-compliant inspection of gas pipes in any location.
