TESTO 750-3 - VOLTAGE TESTER 0590 7503
The TESTO 750-3 voltage tester is an advanced device designed with user convenience and safety in mind. It features a clear LED indicator that allows easy reading of measurements regardless of the meter’s position. Additionally, an extra LCD display shows the current voltage values, making it easier to accurately interpret the results.
The device is equipped with a built-in LED flashlight that illuminates the measurement area, which is especially useful when working in poorly lit or hard-to-reach places. The ergonomic handle with a non-slip ring ensures a secure grip, and the sturdy, reinforced housing protects the tester from damage, increasing its durability.
The TESTO 750-3 not only measures voltage but also quickly verifies whether a device is connected to a power source. Furthermore, the tester functions as a single-pole phase detector and enables the determination of phase rotation direction, which is very helpful when diagnosing electrical installations.
Work safety is enhanced by vibrating overload buttons that prevent accidental activation of the residual current device (RCD) test. Thanks to these features, the TESTO 750-3 is a reliable tool for professionals who value precision, functionality, and user comfort.
