Features Measure a Variety of Data: The digital vibrometer uses a piezoelectric acceleration sensor to convert the vibration signal into an electrical signal, analyzes the input signal, and displays the vibration speed, acceleration, and displacement. Wide Range of Applications: The split type vibration meter is suitable for the measurement of conventional vibration of mechanical equipment, and is widely used in machinery manufacturing, electric power, chemical industry, aerospace and other fields. LCD Display: This digital precision split-type vibrometer has a three-and-a-half backlit display that directly displays measurement results and conditions using an LCD digital display. Easy To Use: This handheld vibration meter can measure ambient temperature with 2 temperature units (℃ and ℉). The default state after power-on is the acceleration measurement unit (m/s2). Intimate Service: We provide 7-day worry-free return and exchange service for all customers.
