Leica's top-class optical quality gives the Wild N3 a bright high contrast image.
For years the WILD N3 has been a standard for precision and reliability. The latest N3 builds on this tradition.
The classical use of the instrument is for geodesy, particularly the measurement of national networks. For the highest accuracy requirements in engineering and for the control of structures , the N3 is widely employed. And there are other new and rapidly growing fields of application.
Today, in industry, laboratories , for research and for special measurements, a precision level of the high est class is needed .
The N3 is designed to meet this multiplicity of requirements , and it incorporates the latest advances in technology.
The N3 is a spirit-level instrument. For very good reasons.
The inherent qualities of a well-designed precision spirit-level produce a basic stability that an automatic level can hardly match .
Although a few first-order automatic levels, such as the WILD NA2 with parallel-plate micrometer, are capable of levelling accuracies approaching that of the N3 , there are circumstances and fields of application where the spirit-level instrument has important advantages.
When running lines of first-order levels in windy conditions, the N3 will give reliable results. The reason is the tubular level, the stability of the instrument.
Industrial users, laboratories and research establishments will find that the N3 is relatively unaffected by vibrations and that strong permanent magnetic fields have no influence at all.
The N3 can be used for measuring small inclinations for river crossings in geodesy and for setting and controlling inclinations in industry .
And it has a powerful telescope with zoom characteristics and alignment properties.
