Product Description

Obsolete effective April 2021.

The Model 140A is a remote in-line DC amplifier designed to be used with bridge-type mV output transducers. The amplifier features five user selectable gain settings with a gain accuracy of ±0.5% and offers a wide bandwidth to 100kHz. The model 140A offers a unique auto-zero function that allows the operator to zero the transducer offset voltage to within ±1.5mV either remotely or by pressing the on-board push button at the users command, usually right before the taking of data. This feature removes any offset drift from the sensor for a more accurate measurement.
