The UNI-T UT372 is a non-contact digital tachometer for measuring rotational speed and counting revolutions without interfering with the equipment being tested. Its USB interface, PC software compatibility and measurement range of up to 99,999 RPM make it suitable for industrial maintenance, inspection and laboratory work.
Key Features
- Non-contact rotational speed measurement from 10 to 99,999 RPM
- Measures RPM and revolution count using a point laser and reflective tape
- MAX, MIN, AVG and data hold functions with adjustable sampling interval
- USB data transfer with compatible PC software for measurement analysis
- Large dual display with selectable laser and cancelable automatic power-off
