SEAWARD 005/6/8 Very high accuracy decade boxes with versatile wide ohm range A versatile range of resistance decade boxes available in 5, 6 & 8 decades. High accuracy and wide range 0.001 Q to 11 MQ 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 any errors due to switch contact resistance and are particularly suited to Pt100 simulation with resolution as low as 0.001 Q (»0.0025°C). Key Features ■ High accuracy 0.01% and high performance ■ Suitable for Pt100 and tranducer simulation ■ 5, 6 and 8 decades ■ Long term stability <20ppm/year ■ Low temperature co-efficient <3ppm/°C ■ Gold-plated switch contacts and solid copper input terminals ■ Negligible thermal E.M.F.s ■ Lightweight / small size ■ Certificate of conformity ■ In-house test figures (optional) Ideal For ■ Engineering departments ■ Laboratories/workshops ■ Calibration houses www.seaward.co.uk/00Series For USA, Canada and Mexico enquiries Tel: +1 (813) 886 - 2775 For all other enquiries Tel: +44 (0) 191 587 8741 Email: sales@seaward.co.uk
