MAGNA - Tesla Meter MG-901 Brand : Magna Model : MG-901 Product Descriptions Handy Tesla Meter MG-901 has evolved further while maximizing the excellent features of the popular MG-801. With MG-901, the display area is greatly enlarged, and the real value and maximum value are displayed at the same time during measurement.This makes it possible to check more accurate data and improve work efficiency.In addition, the addition of a backlight function improves visibility even in dark environments, allowing you to use it comfortably. In addition, the MG-901 has a flattened probe shape, making it easier to pinch the probe during automation.This results in smoother operation and greater precision. In addition, the newly added ''detection mode'' is a function that notifies the value detection within the setting range with a buzzer.This eliminates the need for visual confirmation during work, supporting efficient work. Handy Tesla meter MG-901 is a model that has evolved further while inheriting the excellent features of MG-801.With highly reliable measurement results, ease of use, and the addition of new functions, it is expected to play an active role in various industries and research fields. Product Features   - Simultaneous display of real value and hold value is possible in ''measured value mode'' - Addition of backlight improves workability in dark places! - With the addition of ''detection mode'' (lower limit, upper limit setting), a buzzer will notify you when a numerical value within the set range is detected during measurement. - Compatible with batteries and USB power supply! - Measurement data can be digitally output to a PC via USB (A male - Type C male) connection! - The shape of the probe is flattened, making it easy to fix! * The Measurement Law does not allow domestic sales of measuring instruments with mT / G display switching.
