High-speed Static Strain Data Acquisition Instrument - SE-86H High-speed Static Strain Data Acquisition Instrument - SE-86H

The SE-86H High-speed Static Strain Data Acquisition Instrument, with a maximum sampling rate of 100Hz, is widely used in fatigue test and pseudo-dynamic test, which can capture the slow-changing signal of the whole process from the elastic region to the plastic region. In addition to the measurement of stress and strain signals, physical quantities such as voltage, displacement and temperature can also be measured.
