Features and Benefits

Shimpo’s DT-311A and DT-315A stroboscopes/digital
tachometers incorporate the latest microprocessor technology for
visual inspection applications:

• Aluminum construction provides exceptional durability

• High polish and focused reflector eliminates “blind”

viewing areas

• External trigger allows unit to be automatically

synchronized with equipment

• Continuous duty cycle eliminates need to shut down for

cooling

• Phase shift allows visual analysis of rotating/reciprocating

objects

• High accuracy ( ±0.01% of reading ) is ideal for QC

inspection and process control

• Synchronous output enables strobe to drive other strobes

• Flash timer control conserves flash tube life

Do not disassemble or repair unit while in
operation.

Do not look at the emitted light for long periods
of time; it can be harmful to the eyes.
