Function:
1.Precise Test: This tachometer has high speed and accurate response speed and excellent stability characteristics to accurately test the value of the motor speed and frequency.
2.Strong anti-interference:Digital tachometer has strong anti-interference ability to avoid external magnetic interference and other confusion. Even when the input current is stronger, the frequency and speed measurement is more accurate.
3. Two modes: The frequency tachometer can switch between operating modes including frequency and speed by pressing the key. The setting parameters will be remembered even when the power is off.
4. Clear reading: The tachometer is 0.56 inches, the display screen is 4 digital displays. Clear numbers and fast displays, convenient to read data and know speed.
5.Wide application: the speed measurement range of digital frequency tachometer is 5~9999RPM, the frequency range is 0~98990.1Hz, suitable for the speed detection of various motors.
