Located in Monrovia, California not far from Pasadena, NEFF Instrument Corporation has been the leading manufacturer of high performance data acquisition equipment since its founding in the mid '50s by Glyn Neff.

From the beginning the emphasis has been on making accurate, low noise measurements of millivolt level signals generated by transducers. The very first products were focused on the need to avoid ground related errors. The result was differential input amplifiers developed with circuits which were found to be patentable. Today's products extend to complete systems but are designed using the lessons of long ago.

The engineering and manufacturing departments are managed by people with decades of experience in solving measurement problems and assembling reliable instrumentation.

All design and manufacturing activities are performed on site while sales efforts around the world are supported by representatives and agents.

Neff was founded by instrumentation engineering professionals who have been helping customers solve their measurement problems since 1956. Our data acquisition products range from low-level multiplexed systems to high speed transient measurement systems and are all complete with signal conditioning.

Many digital data acquisition suppliers promote 'do-it-yourself' commodity systems. Although these off the shelf systems may serve adequately in some instances, demanding applications require greater instrumentation skills.

Neff stands apart from the industry trend toward compromise. We continue to provide our customers with solutions that have an appropriate content of 'value added' engineering to solve their more demanding instrumentation applications.

Superior quality also sets Neff products above other suppliers. We have an enviable reputation for quality in engineering design and manufacturing. And we provide extensive support to our customers with application engineering, training, and ongoing product service.
