A data logger is, quite simply, an electronic device that stores data. The data logger has become a revolutionary perfect solution for logging data and is nowadays represented by a wide range of devices, from small one to quite complex data logging systems. Accutherm’s data logger products are digital processor-controlled storage devices that capture and record measurement data over time using built-in or external sensors. The data logged reflects different parameters of sound, temperature, humidity, light, gas, air, voltage, current, shock, vibration, force, water quality, ... obtained through contact or non contact measurement with a data logger.
