The SRN Series are stable, laboratory or portable resistance standards. Their construction and low temperature coefficient makes them ideal for any applications inside or outside of the laboratory. The resistor elements are hermetically sealed to minimize affects of temperature and humidity. The SRN series resistance standards are available in values ranging from 1 miliΩ to 10 GΩ, with custom values available.

Four binding posts and Ground are used for resistance values of 1 MΩ and under. Coaxial connectors are used for resistance values 1 MΩ and higher. The SRN Serie units are resistant to electromagnetic interference (EMI) because of their metal shielding box.
