200 series Standards

  • REFERENCE RESISTANCE STANDARDS
  • LOW TEMPERATURE COEFFICIENTS
  • HIGH STABILITY
  • IMMUNITY FROM ENVIRONMENTAL EFFECTS
  • MAY BE USED IN OIL OR AIR

Ohm-Labs' 200-Series Reference Resistance Standards are designed for maintaining the ohm at levels from 0.1 ohm to ten megohms.

Each standard up to 1K is individually wound from selected Evanohm alloy wire, which has been carefully heat treated for extremely low temperature coefficients of resistance and excellent long term stability.

Above 1 K, a polycarbonate top reduces potential leakage errors, and connections include guarded BPO connectors, which connect to an internal guarding structure. These models may be used as 4-wire, 2-wire or guarded standards. An internal 10 K thermistor temperature sensor is also included.

Initial one ohm standards (model 200) have shown stability of

Each standard is individually manufactured, and can be supplied optimized for 25 °C, 23 °C or 20 °C.

Oil-filled and hermetically sealed, these standards are highly immune from changes in barometric pressure and relative humidity.

All models include ISO17025 accredited calibration, with temperature coefficient data.

In addition to decade values, the 200-Series are offered in –T values for thermometry, and –Q values for use with a Quantum Hall System.

Special values are available upon request.

Notes

  • Tolerance is accuracy at time of manufacture
  • Temperature coefficient is at nominal 25 °C +/-5 °C.
