005/6/8 VERY HIGH ACCURACY DECADE BOXES WITH VERSATILE WIDE OHM RANGE Resistance Decades & Standards A versatile range of resistance decade boxes available in 5, 6 & 8 decades. High Accuracy and wide range 0.001 ohm to 11 Mega ohm are combined in a compact lightweight metal case. The switches have gold plated contacts to ensure a low contact resistance and negligible thermal E.M.F. Some models employ the Waidner Wolf technique to eliminate the errors switch contact resistance and are particularly suited to Pt100 simulation with resolution as low as 0.001 ohm (» 0.0025°C). key feature 005/6/8 High accuracy 0.01% and high performance n Suitable for Pt100 and tranducer simulation n 5, 6 and 8 Decades n Long term stability ± 20ppm/year n Low temperature co-efficient ± 3ppm/°C to + 85 °C n Negligible thermal E.M.F.’s n Gold-plated switch contacts and solid copper input terminals n Light weight / small size n With certificate of conformity n In-house test figures optional n Bracken Hill, South West Industrial Estate, Peterlee, County Durham, SR8 2SW United Kingdom Tel: +44 (0) 191 586 3511 Fax: +44 (0) 191 586 0227 Email: [email protected] Web: www.cropico.com
