Dear Customers and Partners, This catalogue reflects the image of TESA today. It is a company with solid roots in precision metrology that has been able to follow the trend of the times with cutting-edge technologies. Today, just as yesterday, TESA precision measuring instruments and solutions help customers to improve their quality control and increase their productivity. Over the years, TESA has become the home for many renowned brands such as Brown&Sharpe, COMPAC, MERCER, ROCH, ETALON and INTERAPID. All these brands have added a great value and have shaped what TESA products today stand for:...

TESA – 75 years of TEchnology Since its foundation 75 years ago, TESA has distinguished itself in the market through its unique expertise in micromechanics, precision machining and dimensional metrology. With its roots and headquarters in Renens, Switzerland, a region well known for watchmaking, precision engineering and research, TESA has always been dedicated to precision, quality and the sustainability of its products. Today as part of Hexagon Manufacturing Intelligence, TESA is a modern firm with an international footprint operating globally. Our measuring instruments help customers around...

Passion for precision Renowned TESA flagship products, like CCMA dial callipers, the UNIMASTER large dimension gauge, TESATAST level indicators, the IMICRO internal micrometer and our 1D probes – just to name a few – have been a standard in workshops for many decades. With the evolution of digital communication, TESA made the next step and introduced TESA Link Connector (TLC) and wireless module. This allows today’s TWIN-CAL calliper to be equipped with a unique TLC, as easily as replacing the battery cap of the device, enabling bidirectional communication between the instrument and the computer....

INDICATION RELATED DEFINITIONS Technology used for the definition of the indications. Indication F: Indication - D: Anzeige The indication, which provides the information about the measured value, is directly perceptible by human senses. it may be optical, acoustic or based on any other output feature. Displaying devices may either have a digital, analogue or any other special indication. For material measures, the indication matches displayed value. Note: According to the standards, the terms "analogue" and "digital" are only used to differentiate the methods of measurement. Therefore, they...

Metrological Definitions Range of indication F: Etendue d’indication – D: Anzeigebereich The range of indication lies between the high­ est and lowest display values of a ­measuring instrument. Measuring range F: Etendue de mesure – D: Messbereich The measuring range of an indicating device is the range within which the measured values cannot exceed the maximum permissible errors. For tools having several measuring ranges, these errors may vary from a range to another. The measuring range may well be contained within the related whole range of indication. Measuring span F: Champ de mesure – D:...

Permissible limits of a metrological characteristic MPL F: Limites tolérées d’une charactéristique métrologique MPL D: Grenzwerte eines Messtechnischen Merkmals MPL Extreme permissible values of a metrological characteristic of a given measuring equipment, according to specifications or standards of the manufacturer or others. Maximum permissible errors for a metrological characteristic MPE F: Erreurs maximales tolérées d’une charactéristique métrologique MPE D: Grenzwerte für Messabweichungen für ein messtechnisches Merkmal MPE Extreme values of the permissible error for a metrological characteristic...

Relationship with the uncertainty of measurement IS014253-1, which is a part of "Geometrical Product Specification GPS", provides "Rules for establishing the conformity or nonconformity with specifications". these rules are valid for "inspection by measurements of workpieces and measuring equipment". This ISO standard makes allowances for the uncertainty of measurement - or more precisely for the true uncertainty of any measurement whenever the conformity or nonconformity with a given specification must be proved. So, for a workpiece, the specification matches a preset tolerance while being equal...

Traceability to National Standards All measuring equipment consistently used on our production site is traceable to national standards or reference fixtures through our quality management system. Traceability is established by recalibration at regular intervals with docu­mentary evidence as specified in the standards. The illustration that follows shows the hierarchy of calibrations within the chain of traceability. The example set for the transfer of accuracy to our MICRO-HITE height gauges also shows how they are calibrated. Each feature is supplied with ­ a free SCS calibration certificate...
