Daigger LN2 Monitoring Traceable® Memory-Loc™ Thermometer is a liquid nitrogen digital datalogger thermometer providing recorded data in a CSV format that can be transferred from the thermometer to any computer with use of a USB flash drive. The data on each unit cannot be overwritten or modified, thus reliably

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 10 different alarm events can be retrieved with the most current event viewable on the display.

Smart-Alarm™ signals out-of-range conditions

 When an out-of-range condition is sensed, the Smart-Alarm™ triggers. Smart-Alarm™ features visual and audible indicators which signal continuously until acknowledged, even if the parameter returns to the non-alarm range.

USB data transferring

This liquid nitrogen temperature monitor allows recorded data, in a CSV format, to be transferred from the thermometer to PC/Mac with a USB flash drive (not included). Specific software is not needed for this thermometer. Each device has a unique ID that allows multiple units to be used in the same location. 

Datalogging Features

Monitor readings overnight, on weekends, or for any time period with rolling data log. User-defined datalogging interval of one observation/minute to one observation/24 hours. Memory capacity maintains a year of recorded data when using 1 minute intervals and longer when using larger intervals.

Highly accurate and reliable

High-accuracy thermometer has a temperature range of –200 to 105°C and resolution of 0.01 and maintains an accuracy of ±0.25°C across the entire temperature range.

Traceable^® Certificate

Multi-point calibration on an individually-numbered Traceable® Certificate which assures accuracy from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA.  It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. High-impact, chemical-resistant ABS plastic case is 2-3/4 x 4-1/4 x 3/4 inches. Weight is 5 ounces. Supplied: Stainless Steel Probe(s), stand, Velcro®, magnetic strips, wall mount, Traceable® Certificate, and batteries.
