Specialized manufacturer of Digital Pressure Meters and Load Cells



Digital Panel Meter VALCOR series
F3 series

Indicates the change in condition with
change of color. LCD adopted.

F3 type has up to four setting outputs per input channel.
Highly versatile panel meter suitable to various occasions.

  • Current operation state (normal/abnormal) can be found easily by the color of the value (on main display).
  • Measured values can be displayed in 3 colors: red, orange and green, as desired, in areas partitioned by set values.
  • High speed sampling as fast as 2000 samples per second.
  • Fast output enables use for high-speed and safe control purposes.
  • Analog output ranges of 4 to 20 mA, 1 to 5 V and 0 to 5 V included as standard.
  • Output scaling function included, which allows the measurement range to be set variable as desired.
