The Nor130 Series of Sound Level Meters are designed and manufactured to the latest sound level meter standards and comprises two products.
The Nor131 is a Class 1 (precision) instrument whilst the Nor132 is designed in accordance with the less accurate Class 2 requirements.
Both meters offer the same features with exception of the detachable preamplifier which is only available on the Nor131 version.
