OHM-LABS 100 SERIES RESISTANCE STANDARDS
Ohm-Labs 100 series resistance standards are designed for laboratory or on-site calibration. With their low temperature coefficients they can be used in a variety of environments without loss of accuracy. They are immune to changes in air pressure and relative humidity, and are not affected by moderate vibration or shock.
They exhibit low reactance, making them suitable for use as both DC and AC standards.
All models are housed in a robust, die-cast aluminium housing. The internal shock-absorbing construction reduces the risk of value shifts due to vibration or impact. Connections are gold plated tellurium copper low thermal emf connectors, which accept bare wire, spade lugs and banana plugs.
Included is ISO 17025 accredited traceable calibration, including temperature characterization.
All models are available with an optional temperature sensor connected to the resistor element. Decade and thermometry values are standard. Other resistance values are available on request.
High resistance standards in this line are available in a shielded construction.
