The HARS-LX Series features a continuous rheostat as an option.
  • High accuracy - as good as 20 ppm
  • High stability - as good as 5 ppm/yr
  • Over 55 models available with resistance from 1mΩ to 121.1 MΩ
  • Resolution as good 1 mΩ with a fixed decade or 20 µΩ with a rhostat
  • Low temperature coefficient - as low as 3 ppm/°C
  • High performance silver-clad contacts
  • Hermetically sealed, low inductance resistors
  • No zero correction required
  • For increased accuracy, decades ≥ 1 Ω can be individually trimmed
