OMM 650UC

6 digit UNIVERSAL COUNTER

OMM 650UC is an inexpensive universal counter/frequency meter/clock/timer. The instrument is based on a single-chip microcontroller, which ensures good accuracy, stability and eaType sy operation of the instrument.

  • 6 digit programmable projection
  • counter/frequency meter/clock/timer
  • 0,1 Hz…50 kHz; UP/DW
  • tare/preset/sum
  • digital filters, input filters
  • size of DIN 72 x 24 mm
  • power supply 10…30 VDC/24 VAC
