Photo (SE-1200 Hand-held Digital Engine Tachometer)

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.
