The McKesson Refrigerator and Freezer data logger thermometer is designed to meet today's CDC and VFC requirements for vaccine storage and monitoring. It is a self-contained data logger that requires no PC software to generate a complete Excel .csv report. Monitor both the ambient room and refrigerator (or freezer) temperatures simultaneously. It includes a large, easy-to-read display for viewing the current room and external bottle probe temperatures, min and max recorded temperatures, time, and battery strength. Each thermometer is certified, serialized, and traceable to NIST in Thermco's own ISO17025 Calibration Laboratory, accredited by ILAC-MRA to assure accuracy and compliance with all regulatory requirements. (Accreditation No. 69071).
