Calibration Lab SCS

Calibration Laboratory SCS / ISO/IEC 17025:2017    SN EN ISO/IEC 17025:2018


The calibration of high precision inclinometers requires high quality measuring equipment and environmental conditions.

Our air conditioned calibration lab is equipped with special measuring and calibration equipment  certified by METAS / 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.



For more than 80 years, WYLER SWITZERLAND is specialized in the development, production and distribution of precision instruments to measure inclination. The wide range includes various lines from high precision spirit levels through hand held electronic inclinometers to high-tech sensors for measuring angles in a digital bus system.

The continuously increasing quality expectations as well as the demand for traceability of the  measuring values and calibration data has lead at an early stage to the application for accreditation as  a calibration laboratory. This accreditation has been granted by METAS / Metrology and accreditation Switzerland for the first time in 1993 under their registration number SCS 044.

The Swiss Accreditation Service confirms that a laboratory, which is accredited in accordance with standards ISO/IEC 17025:2017, operates a quality system for its testing and calibration activities that also  meets the relevant requirements of ISO 9001:2015. Further, standard ISO/IEC 17025:2017 covers several technical  competence requirements that are not covered by Standards ISO 9001:2015.

Within the framework of the certification possibilities, WYLER AG can issue 3 types of certificates:

All our products are delivered with a „Declaration of Conformity“ stating that the product is in conformity with the applicable standards as well as with the technical specification published in our sales documentation.

The WYLER Certificate

For products respectively measurements for which our laboratory is not accredited (e.g. straight and angular knife edges, special setting squares, etc.) we can issue a „WYLER certificate“. The instruments  or squares are inspected according to the relevant standards.


The certificate issued consists of a  onfirmation that the measuring object is in accordance with the respective standard and of the  easuring results recorded.

The SCS Certificate

The measuring instruments respectively the surface plates or setting angles are inspected and certified  according to the relevant standard. The certificate issued consists of a confirmation that the measuring  object is in accordance with the respective standard, that it has been measured and certified according  to the procedures prescribed by METAS / Metrology and accreditation Switzerland. All the respective  traceable measuring results are part of the certificate.


Surface plates are the basis of high precision measurements in production as well as in laboratory  areas. Often this fact is not sufficiently taken into account and the surface plates do not show the  surface quality required for the measuring precision expected. Frequently the granite surface plates are locally worn, and falsify thus the measuring results.

This uncertainty can be eliminated by a periodic calibration of the surface plate and corrections where necessary. Most quality certificates require imperatively a valid calibration certificate of the measuring equipment used, in order to be accepted.

WYLER SWITZERLAND, traditionally specialized in the field of flatness measurements, can offer a very competent calibration service. Accredited as a calibration laboratory SCS since 1993, WYLER  SWITZERLAND assures a professional calibration service for straightness, flatness, and rectangularity.

The measurement / calibration as well as a possible reconditioning are executed by well trained staff using high quality measuring instruments and software according to accredited procedures (based on  ISO 1101).

These services are made at the WYLER factory under ideal conditions. On special request, particularly for very large objects or for a large number of objects, on-site service can be provided. The calibration is done according to the requirements specified in our SCS accreditation, or according to special WYLER procedures for non accredited measurements.
