Data Loggers
Data loggers automatically record precise measurements even when personnel cannot be present. The portable designs feature internally or externally located sensors that have exceptional sensitivity to record data in any application or environment needed. These electronic instruments have programmable tracking in single or multi-channel options. Enabling reading over long periods of time, the data loggers alert if conditions are abnormal for safety and optimum testing quality through visual or auditory alarms.
