Key construction features

• 150 cm continuous neoprene contact strip – flexible enough to follow sharp undulations and soft ridges, yet dense enough to maintain a low contact resistance (< 20 Ω).

• Twin low-friction rollers with sealed bearings let the electrode roll rather than scrape, eliminating snagging on rough aggregate and reducing operator effort by up to 40 % in field trials.

• Balanced mass (≈ 2.4 kg): heavy enough for consistent pressure, light enough for one-handed manoeuvring and safe overhead work.

• Tool-free quick-lock interface snaps straight onto any eRaptor 2.0 frame (PRO / PRO GPS / PRO RTK); firmware v2.3+ auto-detects the roller and optimises sampling speed.

Performance advantages

• Reliable contact on wavy or blistered roofs – the compliant neoprene strip bridges hollows and peaks that lift rigid bars, preventing false negatives.

• Smooth tracking across coarse asphalt – rolling action means less friction, so you cover more square metres per battery cycle and spare the surface from scuff marks.

• Consistent signal integrity – the strip’s embedded copper braid spreads injected current evenly, keeping locator sensitivity within ±2 % of factory spec.

Ready for site life

• IP65 sealed hubs shrug off dust, hot bitumen flecks and light rain.

• Replaceable wear strip: unscrew two end-caps, slide in a fresh neoprene sleeve, and you’re back on the roof in under five minutes.

• Compact transport sleeve fits in the standard eRaptor case alongside the control unit and cables, adding just 25 mm to the lid height.

Whether you’re scanning freshly milled asphalt parking decks, ageing SBS roofs or heavily wrinkled PVC liners, the neoprene roller electrode keeps the eRaptor system gliding—so your crew finishes faster without sacrificing a single leak.
