     THE ESSENTIALS

     Calipers are the most popular length measuring instruments used worldwide. Owing to their
     simple construction, ease of handling and quick operation, they are a favourite for dimensional
     measurement. The wide variety of models available with specialised measuring faces make
     them universal hand-held tools.
     All TESA, ETALON, INTERAPID branded calipers are recognised for their superior quality –
     and guarantee you precise measurement.
     The flawless guide of the slider on the beam ensures silky-smooth operation whilst also
     preventing the measuring jaws from tilting.
     The choice of material, subjected to precisely defined heat treatment as well as a robust
     design result in further distinctive advantages such as wear and corrosion resistance.
     For quick and easy reading of measured values – one of the essential conditions for the
     assurance of your measurements – we offer conventional vernier models as well as dial
     models for easy reading and digital models for error-free reading.
