Resistance Standards & Decades
Seaward supplies the widest range of resistance standard values available – including the ability to provide precision units for special applications and with special resistance values for customer specific requirements.
These high quality standards are produced under strict manufacturing and quality control conditions to ensure long term stability and permanence of calibration for a wide range of applications.
The range of resistance decade boxes includes 5, 6 and 8 decade boxes which are designed to provide highly accurate and variable standard values of resistance and current for calibration, comparison and test applications in electrical and electronic workshops, test laboratories and educational environments
Gold plated brass contacts on the switches ensure low contact resistance and negligible thermal EMF are among a number of design features incorporated in the decade boxes to ensure precise measurement accuracy and stable loads.
