The SRL series are highest performance resistance standards available from IET Labs with the exception of the SR102, SR103 and SR104. The SRL Precision Resistance Standards utilize multiple resistor elements sealed in an exopy housing or custom oil-filled hermetically sealed Bulk Metal® foil resistors.
