Neff Instrument Corp.

Located in Monrovia, California not far from Pasadena of Rose Bowl fame, 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.
