Multi-channel Dynamic Strainmeter DS-50A

Cable-connecting up to 20 units, 50 channels per unit, allows simultaneous sampling measurement of up to 1000 channels. Capable of measuring 100-Hz occurrences at a fastest sampling of 1 kHz. Allows cable connection between devices of as much as 100 m, for wide-area, multi-channel dynamic strain measurement not possible with conventional dynamic strain measuring instruments.

Multi-channel Dynamic Strainmeter DS-50A
Features
  • Simultaneous measurement of 20 sets (1,000 channels) is available at the maximum.
  • 1 kHz sampling at the fastest when 1 set is used.
  • Accommodates mixed strain and voltage units
  • Comes standard with measurement software
