The DT-205L-S12 DT-207L-S12
Infrared Non-contact Tachometers incorporate laser
technology and
user-friendly functions as our DT-205L/207L
tachometers.
The DT-205L-S12and DT-207L-S12 laser tachometers provide
exceptional accuracy in measuring
speed and length via 12" wheel; the larger wheel rotates more
slowly than a standard 6" wheel,
enabling reliable and safe registration of high speeds.
These superior tachometers also feature a
contact adapter, conveniently allowing both non-contact and
contact rpm measurement.
