PTW – The leading provider of dosimetry and quality control equipment for radiation medicine
PTW designs, develops, manufactures and distributes high
quality dosimetry and quality control equipment mainly for use
in the medical field, especially in radiation therapy, diagnostic
radiology and nuclear medicine.
Design and production of mechanical, electronic and software
components are all done in house. We operate a well-equipped
and modern workshop with ten CNC machines. Our products,
especially the PTW ionization chambers and electrometers, are
well known throughout the world and are recognized for their
workmanship and high level of quality.
PTW is the market leader in its major product lines. The PTW
distribution is organized internationally. A number of exclusive
PTW representations are established in many countries around
the world.
Second production site in Umkirch, Germany
Global headquarters in Freiburg, Germany

PTW-Freiburg operates Germany’s first Secondary Standard
Dosimetry Laboratory for radiation quantities accredited by the
DAkkS, under direct supervision of the National Laboratory.
It is also a member of the international SSDL network,
organized by the International Atomic Energy Agency IAEA.
We perform radiological calibrations for dosemeters used in
radiation therapy, diagnostic radiology and health physics, which
are directly traceable to the primary standard. Our calibration
lab provides a complete range of radiological calibrations from
low X-ray energies up to 60Co and from low to high dose rates
and is one of the busiest calibration labs worldwide.
The Dosimetry School, founded in January 2014 by the dosi-
metry pioneer PTW, is a new global education initiative aiming
to enhance the understanding and practice of clinical dosimetry
through a series of seminars, workshops and trainings.
Benefiting from the knowledge and experience of the oldest
dosimetry company, “The Dosimetry School” offers the medical
physics community an up-to-date, well-rounded education pro-
gram that provides a good mix of scientific theory and practice.

Dosimetry Pioneers since 1922.
It all started with a brilliant invention – the revolutionary Hammer dosemeter in 1922. Ingenuity coupled with German engineering
know-how shaped the company’s history, leading to innovative dosimetry products that later became an industry standard.
Over the years, PTW has maintained its pioneering spirit, growing into a global market leader of dosimetry and QA solutions well
known for its unparalleled quality and precision. Today, PTW dosimetry is one of the first choices for healthcare professionals in
radiation therapy, diagnostic radiology, nuclear medicine and health physics.
