ESI / IET Labs RS925D Decade Resistance Standard
The ESI / IET Labs RS925D Decade Resistance Standard is a top-of-the-line four-terminal variable decade resistor, purposefully designed for the most rigorous calibration and test applications. Recognized as the world's highest accuracy continuously variable resistance decade, the RS925D stands out in precision and reliability.
Utilizing hermetically sealed wirewound resistors for resistance levels of 1 Ω and above, this instrument ensures superior performance. The resistors are meticulously conditioned under specific power and temperature ranges to cultivate optimal stability characteristics. Users will benefit from an impressive storage stability of better than 5 ppm/year, with performance further improving over time. The low-resistance resistors feature a unique construction that minimizes copper resistance to effectively limit temperature coefficient effects.
This decade resistance box is not just a precision resistance source; it boasts exceptional accuracy, stability, and temperature/power coefficients, making it an essential tool for laboratories. With a fixed minimum resistance of 10 mΩ, it simplifies the calibration process by eliminating the need for zero resistance subtractions; the absolute accuracy is maintained across all readings.
Designed for ease of maintenance, the RS925D allows for convenient calibration without extensive component changes. Users can easily adjust the calibration of resistance steps ranging from 100 Ω to 100 kΩ using accessible trimmers, with options for trimming the lower resistance decades as well.
