Multipurpose Readout units are portable instruments designed for manual data acquisition from geotechnical and structural instrumentation, supporting both electrical and vibrating wire sensors. These devices enable fast and reliable measurement campaigns, representing the ideal solution when continuous automatic monitoring is not required or not feasible. The units are equipped with a high-visibility graphical display, intuitive interfaces, and battery-powered operation, allowing direct field use even under harsh environmental conditions. Thanks to compatibility with a wide range of sensors and output signal types (analog, mV/V, 4–20 mA, vibrating wire, temperature), the GESTECNO handheld unit represents a universal and flexible solution for measurement, verification, and testing activities.
