## Long description

The Unit UT372D 2-in-1 Digital Tachometer and Contactless Speedometer is a professional-grade measuring instrument designed for high-precision rotational and linear speed monitoring. By integrating both contact and non-contact measurement technologies, this device offers exceptional versatility for industrial maintenance, quality control, and mechanical engineering tasks. It features a high-contrast rotating backlit LCD screen, ensuring clear visibility in various lighting conditions, and supports Bluetooth connectivity for seamless data management via a dedicated mobile application.
Advantages
This tachometer stands out due to its dual-mode functionality, allowing users to switch between optical non-contact measurements and physical contact measurements effortlessly. The inclusion of advanced data processing features such as MAX, MIN, and AVG modes, combined with internal data logging for up to 10 groups, provides comprehensive insights into machinery performance. Its ergonomic, lightweight design ensures comfort during extended use, while the automatic power-off feature helps preserve battery life during field operations.
Suitable for
Monitoring rotational speed of motors and engines
Measuring linear speed of conveyor belts
Checking frequency of rotating machinery components
Calculating length of moving materials
Industrial maintenance and quality assurance testing
When it may not be suitable
This device is not intended for use in environments with extreme temperatures outside the specified operating range or in highly corrosive atmospheres that could damage the sensor components. It is also not suitable for measuring speeds of objects that do not provide a clear optical contrast for non-contact mode or a stable contact point for the contact probe.
Key specifications
Non-contact RPM range: 1–99,999 RPM
Contact RPM range: 1–19,999 RPM
Measurement accuracy: ±0.02% ±1 digit
Connectivity: Bluetooth for mobile app integration
Data functions: MAX/MIN/AVG, Data Hold, 10-group logging
Power supply: 3 x 1.5V AAA batteries
Dimensions: 176 x 63 x 38 mm
Weight: 181 g
How to use
To perform a non-contact measurement, apply a piece of reflective tape to the rotating object and point the laser sensor at it from a safe distance. For contact measurements, attach the appropriate probe tip or measuring wheel to the device and press it gently against the center of the rotating shaft or the moving surface. Use the function buttons to toggle between modes and view real-time data on the rotating display. Data can be saved to the internal memory or synced via Bluetooth to the mobile app for further analysis.
What to consider before purchase
Ensure the measurement range meets your specific machinery requirements
Verify that the reflective tape is compatible with your target surface
Check if your mobile device supports the required app for Bluetooth data logging
Consider the need for spare AAA batteries for long-term field use
Usage recommendations
Always ensure the device is held steady during measurement to maintain the specified accuracy. When using the contact method, apply light, consistent pressure to avoid slippage or damage to the rotating component. Regularly clean the optical sensor lens to ensure reliable non-contact readings.
