Strain Module, type NDIS (2 channels) to be used in combination with 701955 or 701956 NDIS bridge head. Using the strain module and strain gauge the ScopeCorder can detect and display mechanical stress (strain). It works on the principle that the resistance value of a metal foil changes as it expands and contracts. Applicable to DL350, DL850 series, DL750 series and SL1000.
