HEF-17 Pulse Eddy Current Metal Pipe Wall Thickness Testing
Instrument
Functional features
*There are shortcut keys and LCD screen on the probe, which can
display the working status and detection data in real time, and the
work efficiency is greatly improved without frequent operation of
the host during the detection process.
*The probe adopts electronic focusing technology, which has higher
spatial resolution, greater recognition, and stronger
anti-interference ability for local corrosion defects.
*Not sensitive to the shape of defects, it can detect the wall
thickness corrosion or other thickness reduction defects of metal
members "with cover layer (insulation layer, cooling layer,
protective layer, etc.)".
*Inspections can be done when the equipment is running (High
temperature, low temperature, materials in the equipment etc.)
*Materials that was detected: Detection of remaining wall
thicknesses ferromagnetic metal material such as carbon steel, low
alloy steel
It can also detect the remaining wall thicknesses of stainless
steel, aluminum alloy and other non-ferromagnetic metal materials
*Cladding materials: Non-conductive, non-magnetic materials(
asbestos, foam etc.), metal mesh, iron, aluminum and other
protective layer.
*AC/DC hybrid power supply, built-in rechargeable lithium battery
continually working more than 8 hours.
*Fully sealed IP64 anti-dust and anti-splash design, silicone
sheath anti-drop and anti-vibration design, more suitable for harsh
working conditions.

(Extended function) Multi channel pulse eddy current C-scan
continuous corrosion measurement
*The "probe ring" integrates multiple probes uniformly distributed
along the circumference, which are buckled on the outside of the
pipeline cover layer and continuously scanned manually (or
electrically) along the longitudinal axis, improving the density
and coverage of detection points.
*C-scan imaging, automatically analyzing the remaining wall
thickness and presenting warning areas.
*When selecting the suspected defect area, the remaining wall
thickness value will be automatically displayed for further
analysis.
