The Handheld Drum Vibration Tachometer is used to check vibration frequency directly from a vibrating surface. The device is placed in contact with the drum to capture vibration movement and convert it into readable vibration-per-minute values. When vibration levels are high, indirect contact through the operator’s hand can be used to dampen excessive movement while still capturing accurate readings.Attributes:• Readings can be extrapolated to one-quarter increments.• Assists in monitoring changes in vibration intensity.• Helps evaluate operating stability during rotation.• Provided with 1000 to 2000 with a 50 revolutions per minute interval between reeds.• Provided with 2000 to 4000 with a 100 revolutions per minute interval between reeds.Applications: The Hand Held Drum Vibration Tachometer is used by placing it directly on a vibrating drum surface to measure vibration frequency, allowing operators to observe vibration behavior during active operation.
