DT-311A Stroboscope
The DT-311A Stroboscope
provide the illusion of "stopped motion": by adjusting the
strobe’s flash rate,
equipment and printing appear to be standing still or in slow
motion.
Our strobes also measure rotational (RPM) or reciprocating
(strokes per minute) speeds with the same
precision as an electronic digital tachometer.
DT-311A Stroboscope
| Model | Description |
|---|---|
| DT-311A | Stroboscope (115VAC) |
| DT-311A | Stroboscope (220 VAC, 50/60 Hz) |
Stroboscope is ideally suited for printing inspection, motion
analysis, preventive maintenance
and speed measurement of repetitive motion, our strobes provide
timely data on vibrating parts,
leaks, spray patterns and a variety of industrial and scientific
operations.
Don’t be fooled… while the DT-311A stroboscope is extremely easy to
operate via its lightweight
and compact design, its rugged metal construction provides unequaled
reliability in the harshest
environments.
