This ensures safety and prevents interference with the operation of sensitive equipment, making it an essential tool for industrial maintenance, automotive diagnostics, and mechanical engineering tasks.
Advantages
The primary advantage of the Uni-T UT372 is its ability to deliver highly accurate measurements across a wide range of speeds, from 10 to 99,999 RPM. The device features a sophisticated optical system that maintains stability and reliability, whether monitoring slow-moving components or high-speed motors. With integrated MAX, MIN, and AVG modes, users can easily analyze performance trends over time. Furthermore, the inclusion of a USB interface allows for seamless data transfer to a computer, facilitating detailed reporting and long-term analysis of machinery health.
Suitable for
Industrial machinery maintenance and diagnostics
Automotive engine and fan speed testing
Mechanical engineering research and development
Quality control in manufacturing environments
Monitoring rotating components in HVAC systems
When it may not be suitable
This device is not suitable for measuring the speed of objects that cannot be marked with reflective tape, as the optical sensor requires this reference point to function correctly. Additionally, it is not designed for use in environments with extreme levels of ambient light or dust that could obstruct the laser path.
Key specifications
Measurement range: 10 to 99,999 RPM
Accuracy: ±0.03% for 10–99 RPM; ±(0.04% + 2) for 100–99,999 RPM
Measurement distance: 50 to 200 mm
Counting function: 0 to 99,999
Sampling interval: 0.5 to 255 seconds
Interface: USB for data transfer
Power supply: 4 x 1.5V (LR6) batteries
Dimensions: 184 x 56 x 34 mm
Weight: 100 g
How to use
To begin, apply a small piece of the provided reflective tape to the rotating surface of the object you wish to measure. Ensure the surface is clean and dry for optimal adhesion. Power on the device and point the laser sensor toward the reflective tape, maintaining a distance of 50 to 200 mm. The tachometer will detect the reflections and display the real-time RPM on the 5-digit LCD screen. Use the mode buttons to toggle between MAX, MIN, and AVG readings as needed. For data logging, connect the device to your computer via the included USB cable and utilize the provided software to record and analyze your measurements.
What to consider before purchase
Ensure the rotating object has enough space to apply the reflective tape.
Verify that the operating environment is within the recommended distance range of 50–200 mm.
Check if your computer system is compatible with the provided data analysis software.
Consider the need for spare batteries, as the device requires four LR6 cells.
Usage recommendations
For the most accurate results, ensure the reflective tape is applied securely and that the laser is aimed perpendicularly to the surface. Regularly clean the optical lens with a soft, dry cloth to prevent dust buildup from affecting measurement precision.
