DT-2268 Photo Tachometer is a portable, dual-function digital tachometer that combines non-contact photo sensing and physical contact measurement in a single handheld unit.
Features :
- World’s patent, multi-functions, one instrument combine photo tach. { RPM } & contach tach { RPM, m/min, ft/min }
- Wide measuring range from 0.5 to 100,000 RPM.
- 0.1 RPM resolution for the measured value < 1000 RPM.
- High precision with 0.05% accuracy.
- Laser light beam for photo tachometer, long measuring distance up to 50 cm at least.
- Large LCD display.
- High visible LCD display gives RPM reading exactly with no guessing or errors & saves battery energy.
- This tachometer used the exclusive one chip MICRO-COMPUTER LSI circuit & crystal time base, offer the high accurate measurement & fast sampling time.
- The use of durable, long lasting components, including a strong, light weight ABS plastic housing, assures almost maintenance free performance for many years.
- The housing cabinet has been carefully shaped to fit comfortable in either hand.
