The Concrete Maturity Logger is a self-contained, microprocessor-based data-logger that can be embedded directly into a concrete structure. The logger measures, processes, and stores maturity and temperature data within the concrete itself. It is extremely rugged and operates continuously with no permanently-affixed external devices. The logger processes temperature data in real-time to calculate and store concrete maturity data (i.e., concrete strength). It stores the maximum and minimum temperatures and time at which they occur.

Typically, the maturity logger is used when real-time strength measurements are needed. It uses a precision thermistor to provide highly accurate temperature measurements. The precision thermistor eliminates any need for temperature calibration.

Each logger has a unique serial number.

  • Processes temperature data in real-time to calculate and store maturity data
  • Use when real-time strength measurements are needed
