DT-1236L Digital tachometer is a Photo tachometer and contact tachometer in one precision instrument. Integrated laser for improved accuracy at a further distance in photo mode.
A multipurpose photo and contact tachometer designed to accurately measure RPM, m/min and ft/min from up to 200 cm away with a laser light source. An accuracy rating of 0.05 percent, one of the best in the industry, makes the DT1236L the perfect item for those who need a tachometer.

The DT1236L stores the last value measured along with the minimum and maximum values from its lifetime. 

The DT1236L utilises an exclusive one chip microcomputer LSI circuit and a crystal time base to ensure that it retains its impressive accuracy rating. The body of the tachometer was built out of durable, lightweight plastic to ensure its suitability for use in the field.
