Precision decade box 3000RS

for resistance

Decade resistances from 1 Ohm to 10MOhm Temperature co-efficients as low as 0.1ppm/°C Annual stabilities of better than 5ppm Precision decade resistance reference The 3000RS is a modern precision resistance standard offering annual stabilities of better than 5ppm without the requirement for an oil or air bath, with temperature co-efficients as low as 0.1ppm/°C Using ultra-high precision, 4 wire hermetically sealed oil filled film resistors for values from 1 Ohm through to 100 kOhm, and precision resistors for the 1 MOhm and 10 MOhm values. The 3000RS is suitable for roles of both a working secondary set of resistors or a primary resistance reference. Using the 3000RS with the 8500 Low Thermal Scanner provides an automated solution for the calibration of precision multimeters. The 3000RS comes ready to use with a UKAS 17025 Calibration Certificate
