SR Series Precision Resistance Standard

Very stable - up to 2 ppm/yr

Wide range of values - 1 mΩ to 10 TΩ,

Used by National Measurment Institutes across the world

3 Year Warranty Included

Excellent TC - as low as 0.4 ppm/°C - No need for stabilization in a temperature-controlled bath

Calibration report at 3 temperatures- Temperature chart with alpha and beta provided

Combination of multiple resistors in a single housing and direct plug-in unit for most DMM's Fluke , Wavetek, Agilent, is available

For most resistance values, the SRL series are highest performance resistance standards available from IET Labs. With a very low temperature coefficient these highest stability sealed resistance make an ideal standard for precision applications inside or outside of laboratory environment. Because of the low temperature coefficient, they require no oil-or-temperature bath.

It is possible to maintain SRL resistance standards indefinitely. They are reliable due to their closed, rugged design and sealed resistors. The units are resistant to electro­magnetic interference (EMI) because of their metal enclosure.
