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.
At every place where it is required to measure currents up to 30A , the precision current shunt should be the first choice. Independent institutes have compared the resistor with products made big names companies. In every case, our resistor was found to be better and more stable.
