The PTB (Physikalisch-Technische Bundesanstalt) is the National Metrology Institute (NMI) of Germany. As a higher federal agency and part of the ministry of commerce and energy, their duty is to provide scientific/technical services.
The PTB is the highest instance in all questions regarding correct measurements in Germany. PTB is alongside the National Institute of Standards & Technology (NIST / USA) and the National Physical Laboratory (NPL / Großbritannien) one of the leading NMIs worldwide.
By German law, the PTB has the duty to produce, maintain and distribute physical units (SI units). At two locations in Braunschweig and Berlin the PTB has 1.800 employees in addition to 300-500 guest researchers from all countries of this world.
Since 2015 wekomm has a technology partnership with PTB and is working closely together with the laboratory for Direct Current (DC), Voltages and Resistors. Together we are in the process of improving our extreme precise and long term stable resistors even more.
wekomm is developing and producing special resistors which come very close to the propagated targets like long-term stability, indepence from ambient pressure or humidity. The PTB is verifying those developments directly against the Quantum-Hall-Efect to provide the best possible measurement results. Those results are discussed within the team and influence the development and production of future resistors.
This collaboration already produced some top notch products, like the 10 kOhm reference resistor and both high load resistors with 1 Ohms and 100 Ohms.
