Maxwell 25521 Smart multimeter with temperature and frequency measuring function, characterized by a durable device housing and construction. The device communicates with the smartphone using the free mobile application. The software provides, for example, the possibility to take a photo during a measurement, which is automatically labeled with the measured data and the GPS coordinates of the measurement. It is not necessary to record separately where the measurement was taken, thus a LOG file of the measurement history can also be easily created. The measurement values ​​can be monitored in several ways on the display of the mobile device. The backlit display supports measurement tasks even in darker lighting conditions.
