The "Electronic Pistonphone"
Being a class L calibrator ("Laboratory standard" - previous class 0) the Nor1253 is often referred to as the "electronic pistonphone" since it maintains an accuracy normally associated with a pistonphone without the need for a barometer to make corrections for variations in the ambient pressure.
Standard class L/class0 version of the Nor1253 comes in two versions, ...
