Multimeter UNI-T UT71B

Description

The UNI-T digital multimeter provides a sophisticated measurement technology at a very good price / performance ratio. Different models cover the entire range, from the good entry-level model to precise measurement devices with a precision of 0.05% deviation.

Besides the quality, the measurement devices distinguish by their ease of use, good legibility of the display and sophisticated measurement functions. UNI-T digital multimeters also fulfill the important details of everyday measuring, such as the almost immediate response of the continuity test, reliable measurement results, and conservative use of the battery. If you have ever worked with a digital multimeter from one of the various cheap manufacturers, you are familiar with problems such as continuity tests taking several seconds, noticeable deviation of measurement results if the battery is low, and rapid battery drain...

Data Logging

The built-in memory of the UNI-T UT71B can hold up to 100 measurements for later recall. Measurements can be stored automatically in 0 ~ 255 second intervalls. Using the USB interface it is possible to transfer the recorded data to the PC for later analysis.

USB Measurement Possibilities

The UNI-T UT71B has a built-in USB / RS232 interface for PC communications. Combined with its software, it allows receiving, recording and performing long time data measurements with graphical visualization.

It can save up to 2 Sa/s, depending on the measurement function selected (DCV, Resistance, Frequency, ...)
