The SE-1200 is a new-designed appearance of our long-selling digital engine tachometer. Indigo blue in color, it is designed to fit snugly into the palm of your hand. A memory function (10 data) has been added to the original specifications of previous model.

Featute

  • A large-size LCD device has been incorporated into the compact, lightweight body.
  • Easy and safety operation by non-contact measurement.
  • Measurement can be performed in 1 r/min resolution covering a wide measurement range.
  • The cylinder/cycle settings enable use with various gasoline engines.
  • Equipped with a convenient memory function for checking of the measurement results (up to 10 data can be stored in memory.)
  • Over-range display function—if the measured value exceeds the measurement range, the maximum value for that range is displayed together with an “ERROR” mark.
  • After measurement has been completed, the latest measured value is displayed for approximately 30 seconds.
