The new PeakTech 3442 is a practical digital multimeter for high demands in a heavy-duty design with a variety of useful measurement functions. The measurement display of the device can be switched between a 6,000-digit LCD and a high-resolution 60,000-digit LCD at the touch of a button, with all measurements being recorded as true effective values. In addition to the extensive measurement functions for current, voltage, capacitance, resistance and much more, this new development also has a 4-20 mA% current loop measurement, a low-pass filter and an auto-hold function. The measured values can also be displayed live via Bluetooth using PC software or an app for Android and iOS devices, recorded in tabular form and, for example, sent by e-mail for further processing. During development, special emphasis was placed on user protection through the shock and impact resistant housing and the high overvoltage category. Due to the extensive measuring functions and the intuitive operation, this device is ideally suited for every electronics technician, technician and engineer who attaches great importance to a precise, indestructible and technically efficient multimeter.
