The Cropico high-dissipation decade resistance box with UKAS calibrated is constructed using the same high-quality components and housed in a light alloy ventilated case. Its required resistance is selected by the 6 rotary switches. This is fully serviceable and can be repaired in our workshop should the more enthusiastic user damage the units with high overloads.

Five decades are 10 x 0.1ohm, 10 x 1ohm, 10 x 10ohm, 10 x 100ohm and 10 x 1kohm
Accuracy is 5%
Resistance resolution is 0.1ohm
Temperature coefficient is ±3 ppm/°C, ±5 ppm/°C
Length of 130mm, width of 390mm and height of 105mm
Power rating is 5W
Operating temperature ranging between -50°C and 125°C
