DT-200LR-S12 Handheld Digital Laser Tachometer
Operation Manual
• When using the 12” wheel, do not use the extension shaft - the wheel
may fly off the shaft and cause damage.
• Although the tachometer alone is able to achieve the higher
ranges listed in the Range and Accuracy table on page 3, the wheel
attachment has a maximum speed limitation of 5,000 FPM (for safety
reasons).
• Laser radiation may be harmful to the human eye. Avoid direct
exposure of human eyes to laser light. Eye damage can result.
• Never point the unit at another person.
• Keep out of the reach of children.
• Avoid indirect exposure via reflective materials such as glass and
mirrors.

Series DT-200LR Combination Contact/Non-Contact Laser Ta-
chometers Laser-enabled precise RPM measurement up to 20
feet.
The Series DT-200LR digital tachometers incorporate laser
technology yet retain our hallmark rugged construction and reli-
able quality components. Units offer incredible value and versa-
tility as they can operate in non-contact and contact applications.
These instruments feature a field-upgradeable contact adapter for
linear rate measure, conveniently allowing both non-contact and
contact measurements. Incorporating the precise laser technol-
ogy and user-friendly functions as the DT-200LR tachometer, the
DT-200LR-S12 provides an exceptional accuracy in measuring
speed and length via its 12” wheel. The larger wheel rotates more
slowly than a standard 6” wheel, enabling reliable and safe regis-
tration of high speeds.
All Series 200LR units come standard with a NIST traceable cali-
bration certificate. We’re confident you’ll agree that these fine units
are the most advanced handheld tachometers on the market!
