## Description Fisher Scientific™ Traceable™ Excursion-Trac™ Datalogging Thermometers are ideal for monitoring temperatures in refrigerators, freezers, water baths, heating blocks, and incubators. With user-defined time intervals. High-accuracy thermometer has a temperature range of -50 to 70°C and resolution of 0.01 and maintains an accuracy of ±0.25°C across the entire temperature range.   - Stores up to ten unique alarm events - Meets current CDC requirements for vaccine storage and monitoring - Rolling memory structure, maintains most recent 525,600 temperature observations - Memory can be cleared on unit after downloading data to USB stick - Hassle-free retrieval of data; unit can remain in use while downloading and analyzing data - Status indicators: Low battery, memory full, USB data transfer and active alarm state - Traceable to NIST for accuracy - High-impact, chemical-resistant ABS plastic case measures 7 x 10.8 x 1.9cm (2.75 x 4.25 x 0.75 in.) - Datalogging Capacity: 525,600 temperature observations  - Weight: 5 oz. **Hi/Lo Alarms and Time/Date Stamps** - Alarm tracking feature stores in memory each alarm event detailing when the alarm state occurred, as well as when the unit returned back to within range - Alarm state indicators include visual LEDs, audio alerts, and flashing LCD segments - Data for up to ten different alarm events can be retrieved with the most current event viewable on the display **USB Data Transferring** - New feature allows recorded data (CSV file) to be transferred from thermometer to PC or Mac™ using a USB flash drive (not included) - No software is needed for computer interface - Each thermometer has a unique ID allowing multiple units to be used in the same location **Data-Logging Features** - Monitor readings overnight, on weekends, or for any time period with rolling data log - User-defined data-logging interval of one observation/minute to one observation/24 hours - Memory capacity maintains a year of recorded data when using one-minute intervals and longer when using larger intervals **Bottle Probe Features (Cat. Nos. 15-081-125, -126, -128, 129 do not come with bottle probes)** - Bottle probes are sealed in a miniature bottle (1 x 2.5 in.) filled with nontoxic glycol - Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration) - Eliminates concerns about incidental contact with food or drinking water - Temperature-buffered bottle sensor eliminates rapid changes when refrigerator door is opened - Ideal for use in monitoring storage conditions for vaccines or other important samples **Note: ** Batteries are designed for power back-up and will last for 7 days.  This unit comes standard with an AC power adapter, which is recommended for standard use. ## Specifications ||| | ------------ | ------------ | |Description|1 Probe, 5/16 in. dia. x 3/4 in. long| |Includes|Stand, Velcro magnetic strips, wall mount, batteries| |Accuracy (Temperature)|±0.25°C| |Product Type|Datalogging Thermometer| |Temperature Resolution|0.01°| |Temperature Range (Metric)|-50.00° to 70.00°C (-58.00° to 158.00°F)| |Certifications/Compliance|ISO 17025, A2LA, NIST| |Data Memory|525,600 temperature observations| |Length (English)|Cable: 10 ft.| |Resolution (Relative Humidity)|0.01°|
