Liquid Nitrogen Temperature Monitor

  • Memory capacity of 525,500 temperature observations
  • 4 calibration points (-196°C, -80°C, 0°C and 100°C)
  • Range: -200˚C to 105˚C (-328 ˚F to 221 ˚F)
  • Accuracy of ±0.25°C across the entire temperature range
  • Resolution of .01°
  • Monitors readings for any period of time

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 and data can be deleted from memory. 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.
