Portable tachometer with auto-ranging 1 to 60,000 rpm, memory function, pulse output, long battery life, and user-friendly operation for accurate speed measurement, data recording, and flexible industrial and field applications.

The portable tachometer is designed with auto-ranging measurement from 1 to 60,000 rpm, and accurate speed detection is achieved across a wide measurement range. In addition, the decimal point is adjusted automatically based on the displayed value, so readability is improved while measurement precision is maintained.

Moreover, a memory function is provided, and measurement results such as final value, maximum value, minimum value, and cumulative count are stored. These values can be displayed sequentially, so data can be reviewed later even if it is not checked during operation.

Furthermore, a pulse output function is included as standard, and it can be used for marker signals or as input for F/V converters and counters. As a result, system compatibility is expanded, while signal utilization is enhanced.

In addition, simple operation is supported through two buttons, and reliable control is achieved during measurement. Therefore, ease of use is improved, while stable operation is ensured.

Moreover, the device can be mounted on a tripod, and flexible installation is supported for different measurement environments. As a result, hands-free operation is enabled when needed.

Finally, a dual power supply system is supported, and up to 50 hours of continuous operation is achieved with alkaline batteries. A low battery warning is provided, and external DC power can also be used. Therefore, long-term and stable measurement is ensured in both portable and fixed applications.

Overall, the portable tachometer provides wide measurement range, convenient data storage, and flexible power options, so it supports accurate and efficient speed measurement in industrial, maintenance, and field use.
