The PeakTech 3350 has been specially developed for use in trade and industry and offers a variety of useful functions that simplify daily work, especially in dark or noisy environments. The illumination of the large LCD display is automatically activated by a photodiode in dark environments, and there is also a bright LED torch on the back for illuminating the measuring station. A multi-coloured LED strip is located above the 6000-digit digital display. Depending on the active measuring function, this lights up green during continuity testing, red when voltage is detected in NCV mode, yellow when measuring large capacitances or flashes red in active phase tester mode, for example. It has been manufactured according to the latest development aspects and has a double-insulated injection moulded housing with rubber coating and a service flap on the back, which can be used not only to replace the battery but also to replace the high-quality fuses. The measuring range of this device is selected automatically, which guarantees particularly easy handling.
