Visual testing

HELLING GmbH

Since 1863

Visual testing

In most cases, before complex testing procedures are used, the test object is examined with the eyes - visual testing. If interior spaces are to be inspected, then often endoscopes are used.

HELLING offers various endoscopes

  • rigid borescopes
  • semi-flexible endoscopes
  • endoscopes with UV LED

It is also important to have good and appropriate illumination. Here HELLING offers various lamps in pocket format with white light LED.

You will find an extensive assortment of UV LED lamps under UV lamps.

Other important tools are various magnifying glasses, as well as mirrors and probes for interior inspections.

A variety of gauges and measuring instruments are available for weld inspection. You can find them under welding technology here...

HELLING 3D Laser Scanning Anti-Reflection Spray MATT

HELLING 3D Laser Scanning Anti-Reflection Spray MATT prevents reflections on surfaces to be measured by 3D laser scanners.

The anti-reflective spray is particularly suitable for large measurement objects that are coated with a layer of varnish. For plastic surfaces, the suitability should be checked beforehand.

Substantial improvement in terms of health and environmental protection.

  • Very good wettability of surfaces
  • Excellent matting and coverage
  • Produces a homogeneous, smooth, closed, fine, white powder layer, which enables a precise measuring result
  • Volatile anti-reflective agent, sublimates and evaporates without residue
  • Solvent-free (free from cyclododecane)
  • No dust residues during spraying (therefore gentle on laser fan and test personnel)
  • Post-cleaning with HELLING 3D Laser Scanning Cleaner
