Laboratory equipment DF9272

Laboratory equipment DF9272Suitable for the calibration of various speed instruments, sensors, and speed measurement systems such as speed, zero speed, reverse protection, and overspeed protection, especially suitable for on-site testing and calibration.

We recommendLaboratory equipment DF9272As a standard equipment for laboratory speed calibration.

★ Small size, light weight, truly portable tachometer;

All drive and control components are integrated into a portable aluminum alloy box, which can be easily carried by one person.

★ Smooth rotation, low vibration, low noise, safe and environmentally friendly;

When operating at maximum speed, there is almost no vibration and there is a slight wind speed sound during rotation; The rotating part is enclosed with a protective cover for safe use.

★ Wide speed range and high precision, meeting all high-performance needs;

★ Built in standard speed signal source, one for multiple purposes; The scope of application is broader;

★ Rich functionality, simple operation, and fully automatic verification;

All parameters are set with full numbers, and specialized operations can be completed with just one click on the keyboard. There is also a Windows version of the operating software, which allows for easy device operation, data recording, and report printing through a PC.

★ Automatically store and verify data;

Connect the sensor, press to run, and easily complete the storage and recording of sensor calibration data.
