The Turnigy LCD Tachometer is used to measure the RPM of just about any rotating object. It’s shown here being used by Tony Iannucilli to measure the head speed of Martin Cohen’s main rotor blades on a beautiful fall Florida day. However, it can also be used on airplane propellers, calibrating timing belts, dynamic balancing calibration for flywheels, vibration frequency measurements and more.
Traditional optical tachometers utilize a motor-driven shutter which takes time to match the set rpm due to its need to physically change speed, but the Turnigy LCD Tachometer utilizes a high-speed electronic LCD shutter to measure RPM, which is much faster and more accurate. This makes for virtually no delay when changing the RPM setting and provides accuracy within +/-1RPM. It even offers adjustable aperture settings to allow for use in just about any lighting condition. And as you can see in the photo, to use the tach simply look at the helicopter through the viewing window and adjust the RPM with the “+” and “-” buttons until the rotor blades stop. The RPM is then read on the digital readout.
