Dual Probe Temperature Data Loggers Two models of temperature logger available: vaccine monitoring and ultra low temperature monitoring. No need for PC software, simply view the large display for real-time temperature readings, including ambient room and refrigerator/freezer temperatures. Meeting CDC and VFC requirements, this self-contained logger generates a complete Excel .csv report for easy monitoring. With high accuracy of ±0.3°C (±0.6°F) and NIST Traceable Certificate, record up to 24 million readings on a 2G Micro SD card. Retrieve data easily with USB cable or SD card. Set alarms, view current temperatures and more on the large LCD display. Certified, serialized, and traceable digital temperature logger is the perfect tool for monitoring temperatures in cold chain vaccine transport and storage. With calibration accredited by ILAC-MRA, it ensures accuracy and compliance with regulatory requirements. Included: Ultra Low Temperature Logger Vaccine Temperature Logger 2yr.
