To work with currents up to 30A we have made special resistors which fulfil our quality requirements. Excellent long term stability, very low self heating and a maximum of independence from environmental influences define these resistors as well. All that effort so you can concentrate yourself onto your work and your measurement instrument just do what they are meant to to - their work.
For current measuring shunts we apply the very same requirements as on all of our products. You need to be able to trust them without compromise. To reach this goal, we equipped our Precision Current Shunts with a very low yearly drift of typ. 3 µΩ/Ω per year. Together with an excellent, low temperature coefficient, you can obtain the most precise measurement results possible. As the self heating effect is very low, you do not need to bother about this effect for currents up to 30A.
At every place where it is required to measure currents up to 30A , the wekomm precision current shunt should be the first choice. Independent institutes have compared the wekomm resistor with products made big names companies. In every case, our resistor was found to be better and more stable.
