Daigger Traceable® Memory-Loc™ Datalogging thermometers are high-accuracy thermometers with fixed one minute logging interval and a temperature range of -58° to 158°F making them ideal for monitoring temperature in refrigerators, freezers, water baths, heating blocks, and incubators. The case is made from high-impact, chemical-resistant ABS plastic providing durability for extended use.

The new USB data transferring feature allows recorded data to be transferred from thermometer to PC using a USB flash drive (not included). No software is needed for the interface and each thermometer has a unique ID allowing multiple units to be used in the same location. These thermometers are capable of storing over 1 million temperature observations and raw data on the unit cannot be overwritten or modified when storage is full. An indicator light appears when the memory is 95% full.

The thermometer can store up to 10 unique Hi/Lo alarm events detailing when the alarm state occurred, as well as when the unit returned back to within normal range. Alarm state indicators include visual LEDs, audio alerts, and flashing LCD segments.

The bottle probes are sealed in a miniature bottle (1" x 2.5") filled with nontoxic glycol. The solutions is GRAS by the FDA eliminating concerns about incidental contact with food or drinking water. Temperature-buffered bottle sensor eliminates rapid changes when refrigerator door is opened.

Thermometers meet all current CDC requirements and recommendations for temperature monitoring of vaccine storage as part of the Vaccines for Children program.
