1922 – 2022: 100 Years of PTW

As a pioneer in medical radiation measurement, PTW has always been – and will continue to be – at the forefront of advancing patient safety through innovation and cutting-edge measurement technology.

Our roots go back to 1922 when Dr. Wilhelm Hammer decided to market the first X-ray therapy dosemeter based on an electrostatic relay, a revolutionary new electromechanical component which he had invented three years earlier.

Today, PTW is a key player in the dosimetry market, holding the No. 1 position in many countries and product categories. Supported by the largest sales and service network worldwide, PTW offers the most extensive portfolio of dosimetry technology in the industry – from detectors to water phantoms, from dosemeters and electrometers to intelligent solutions for quality assurance of complex clinical radiation equipment.
