Temperature / Maturity Loggers

intelliRock II loggers are temperature measurement and recording devices designed specifically for embedding in concrete placements and test specimens. The loggers measure and record temperature data at predetermined intervals and durations based on logger model. Maturity loggers also process the time-temperature information in order to calculate and store concrete maturity.
