High-quality materials

A successful product is this combination of high-quality measuring elements, housing and drum materials and highly precise clockwork. It is manually assembled, adjusted and tested. The proven natural hair grid is the most frequently used device to measure humidity. Especially advantageous is the use of synthetic fiber in rooms and temperatures between -10...+40 °C, since no regeneration is required.

  • Precision mechanics clockwork
  • Even long-running quartz clock movement with battery available
  • Clearly arranged results
  • Independant of mains power
