INSPECTION DURING THE COURSE OF THE MANU-
FACTURING PROCESS

Height gauges are single-axis handtools made to measure on a surface plate, preferably on
granite. The TESA-μHITE version being offered in this section clearly shows that combining a
surface plate with any height gauge can create a complete measuring system.
Providing the necessary versatility, they are well suited for dimensional inspection directly
on a machine or a group of machines, usually during the various setting and sampling opera-
tions throughout the whole manufacturing process.
They are specially made for checking parts that are difficult to machine due to their critical
sizes.

TESA-HITE or TESA MICRO-HITE, whether manually operated or motor-
driven, do not require any special skills. Nearly everyone working in the
workshop can use them easily.

SCS Calibration Certificate
The newly implemented TESA-HITE and TESA
MICRO-HITE production line now also includes its own
temperature-controlled laboratory recently certified
by the Swiss Accreditation Service (SCS), so that each
height gauge comes with a SCS calibration certificate
provided free of charge.
The negligible temperature variation along with the
use of high-precision step gauges allow the lowest
uncertainty of measurement to be achieved during the
calibration process.
As a first step, all values needed for automatic com-
pensation for the systematic errors of the finished
height gauge through Computer Aided Accuracy (CAA)
are captured.
Once conveniently calculated, each single compen-
sation value is then stored in the tool memory so as
to allow the automatic calculation of the measured
values during calibration.
Finally, the relevant calibration certificate is issued
based on the values obtained during a new series of
measurements taken at another measuring station,
also equipped with step gauges. The applied calibra-
tion procedure together with the SCS based certifica-
tion ensure that every TESA height gauge is traceable
to national standards.

Height Gauges – One of TESA’s Strengths
TESA offers the largest range of height gauges for
reliable one or two-dimensional measurements. End
users can choose the most suitable model not only
according to the requirements of their metrology
applications, but also according to their financial
resources.
This wide range goes from the simple height and scri-
bing gauge to the motorised vertical column suitable
for high-precision measurements in two coordinate
directions.
