Suitable for
Industrial maintenance and equipment inspection
Testing electric motors and generators
Mechanical diagnostics of rotating machinery
Quality control in manufacturing environments
Automotive engine speed verification
This device may not be suitable for applications requiring contact-based measurements, such as measuring the speed of surfaces where reflective tape cannot be applied. It is also not intended for use in environments with extreme temperatures or high levels of moisture that exceed the device's specified operating conditions.
Key specifications
Measurement range: 10 to 99999 RPM
Technology: Digital contactless
Display type: LCD
Power source: AA batteries
Dimensions: 56 mm x 34 mm x 184 mm
To use the Unit UT371, first ensure that the batteries are correctly installed. Apply a small piece of reflective tape to the rotating object you wish to measure. Turn on the device and aim the sensor toward the reflective target from a safe distance. The tachometer will detect the reflected light pulses and display the rotational speed on the LCD screen in real-time. Ensure the sensor is aligned correctly to maintain measurement accuracy.
What to consider before purchase
Ensure the rotating object is accessible for applying reflective tape
Verify that the target speed falls within the 10-99999 RPM range
Check that you have the necessary AA batteries for operation
Confirm the device's dimensions are suitable for your workspace
Usage recommendations
For the most accurate results, ensure the reflective tape is clean and securely attached to the rotating surface. Maintain a stable distance between the sensor and the target during the measurement process to avoid signal loss.
