The McKesson Ultra-Low Temperature Data Logger with Alarm is designed for precise temperature monitoring of ultra-low freezers. This high-accuracy thermometer features dual probes, allowing simultaneous monitoring of refrigerator and freezer temperatures, with external temperature readings ranging from -112 to 158F (-80 to 70C) and internal temperatures from 32 to 122F (0 to 50C). It can capture approximately 24 million readings, logging data every 10 seconds. The device maintains minimum and maximum readings in memory and allows for user-configurable low/high alarm limits, indicated by a flashing LED alarm light. A real-time display, waterproof external sensors, low battery indication, and a flip-out stand enhance its usability. Data is stored in a .csv file format on a removable SD card, and an optional external power supply is available for continuous operation.
