Compact, durable case of encapsulated moulded epoxy
Constructed using low temperature coefficient resistor wire and gold plated contact switches
Particularly suitable for use in electrical and electronic industrial laboratories
Required resistance selected by the 6 rotary switches
The -B and -C models are suitable for pt100 simulation

The Cropico high-accuracy decade resistance box with UKAS calibration is constructed using low-temperature coefficient resistor wire and gold plated contact switches. This ensures a low contact resistance and a negligible thermal E.M.F. This is particularly suitable for applications such as Pt100 simulation where resolution as low as 0.001ohm (»0.0025°C) is required. Its required resistance is selected by the 6 rotary switches.

Six decades are 10 x 0.001ohm, 10 x 0.01ohm, 10 x 0.1Ω, 10 x 1ohm, 10 x 10ohm and 10 x 100ohm
Accuracy is 0.05% for premium dials
Resistance coils wound in selected low TC wire
Compact, durable case of encapsulated moulded epoxy
Resistance resolution is 0.001ohm
Depth of 80mm, width of 350mm and height of 100mm
Operating temperature ranging between -50°C and 125°C
