COMPENDIUM INCLINATION MEASUREMENT
WYLER AG, WINTERTHUR / SWITZERLAND

The calibration of high precision inclinometers requires high quality measuring equipment and environmental con-
ditions.
Our air conditioned calibration lab is equipped with special measuring and calibration equipment certified by ME-
TAS / Metrology and accreditation Switzerland and covers thus a wide variety of requirements. The calibration range
for instruments and sensors reaches from insignificant angles (0.2 Arcsec) to the full circle (360°). Our laboratory is
also equipped for the calibration of NON-WYLER products.
