N&H Laboratory

In our laboratory, we carry out technical tests and analyzes. Measurements on our own products are free of charge for our customers.
Upon request, we also peform technical analysis for third-party products.

1. Electromechanically Testing

  • Force-Travel performance of control elements (e.g. silicone rubber keypads, membrane switches, tact switches, micro switches etc.)
  • Life Cycle of control elements
  • Abrasion Test of coated and printed surfaces (e.g. legends and coatings of keys, front panels, parts of housings, etc.)
  • 2D / 3D measuring microscope
  • Pressure / Pull Force measurements for checking the strength of material connections, operating forces on control elements (buttons, switches), pull-off performance of films

3D Scope Check

2D Messmikroskop



2. Optical Testing

  • Light density
  • colour coordinates
  • dominant wave lengths
  • brightness control (homogeneity) of displays, backlights, backlighted keyboards and pictograms, etc.

3. Material Testing


  • Resistivity and volume resistivity of surfaces
  • Powder Resistivity Tests

4. Further Testing

    • Climatic exposure test cabinet (Temperature -70°C bis +180°C /
      Humidity10% bis 98%)
    • Cable Test
    • Sound level measurements (Frequency diagram)
    • Prototyping with 3D printer
    • Device construction with CNC engraving and milling machine
