1 Ω & 0.1 Ω Resistor with Carrying Case
The model 9210A MI-Type Standard has been developed through years of research by NRCC and Measurements International and is now offered as an improved resistor design to replace the L&N Thomas-Type One-Ohm Standard as well as other values. These improvements have been achieved through a new annealing process of the element and changes in the structural mounting. Historical data is now proving the model 9210A to be the most stable oil-filled resistor commercially available.
The model 9210A features a long term drift rate of less than 0.2 ppm per year and a temperature coefficient of fewer than 0.05 ppm/°C.
