Please note that there are possibilities of individual differences in a color tone on display devices such as LEDs, fluorescent display tubes and LCDs due to manufacturing process or production lots.

F331 is a digital indicator for strain gauge sensors to measure load, torque, pressure and displacement. Compact and simple configuration, practical machine with features such as hold and judgment.
Features
  • Judgment function
    Upper and lower limit comparison and judgment result output
    Output (2 points) : Selectable from OK・NG・HH・HI・LO・LL
  • HOLD function
    Hold function with the speed of A/D converting 300 times/sec. (Sample・Peak・Bottom・P-P)
  • Wealth of interface
    USB as a standard feature. BCD output, D/A converter(Current output), RS-485(Select from Modbus-RTU and original format), RS-232C are available as an option.
  • Special PC application software
    We prepared the special software that can easily set up F331, downloading of measured values and analyzing on a PC.
