Make data collection from your existing load frame, consolidometer or other lab equipment simple and inexpensive with one of Humboldt's MiniLoggers. The HM-2325A and HM-2330D MiniLoggers. are simpleto-use, four-channel, stand-alone, digital data loggers specifically designed for use in Soil Testing (Triaxial, Consolidation, Direct Shear, CBR/LBR Unconfined Compression); Asphalt Testing (TSR, Hveem, Flow/Stability), and Cement Testing (Soil/Cement and Cement Cubes).

Humboldt MiniLoggers increase lab productivity and cost effectiveness by freeing up technicians while test data is recorded automatically. Both units are fully configurable for automated start, stop and log-rate conditions; and can hold up to 300 readings per channel. Both units also include Humboldt Materials Testing Software (HMTS), which provides expanded control and reporting capabilities from a computer.
