The PeakTech 3445 is a practical digital multimeter designed for heavy-duty use, featuring a wide range of useful measurement functions. A unique feature of this series is its bright LED flashlight, illuminated function buttons, and a rotary selector switch, allowing you to use this IP67 waterproof device even in poor working conditions and total darkness. In addition to extensive measurement functions for current, voltage, capacitance, resistance, and more, this device also includes temperature measurement, Max/Min, Peak, and a Data Hold function. Via Bluetooth, the measurement values can be displayed live using PC software or an app for Android and iOS devices, recorded in a table, and sent via email for further processing. Special attention was given during development to user protection through the IP67 waterproof, shock-resistant housing and the high overvoltage category.
