Accumeasure D Series Amplifier by MTI Instruments

The Accumeasure D series amplifier offered by MTI Instruments uses advanced technology to change a reliable capacitive electric field measurement into a highly accurate 24 bit digital reading. This eliminates errors related to analog filtering, linearization, range extension and the summing of channels to achieve thickness or step measurements.

The Accumeasure D amplifier features a new revolutionary design and its frequency response and averaging are now digitally controlled. MTI Instruments also provides a wide range of probes that can work at multiple ranges via digital range extension.
