Registradores de datos
These Traceable® Excursion-Trac™ USB Datalogging LN2 thermometers monitor the temperature in the liquid nitrogen Dewars, covering cryogenic needs for sensitive, irreplaceable biological samples.

  • Liquid Nitrogen USB datalogging thermometers with user-defined time intervals
  • Memory capacity of 525600 temperature observations and one year when using one minute intervals
  • Four calibration points (–196 °C, –80 °C, 0 °C, and 100 °C) with cable length of 10'
  • Recorded data (CSV file) may be transferred from base unit to PC or Mac using a USB flash drive, with no additional software needed
  • Smart-Alarm™ features a visual/audible alarm that continues to alarm even if unit returns to non-alarm conditions
  • Monitors readings for any period of time
  • Status indicators: low battery, data downloading status, flashing LCD symbols, and audio alarm indicating active alarms

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.

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 transfer: 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 1 year of recorded data when using 1 minute intervals and longer when using larger intervals. After transferring the data onto a USB stick, it can be cleared from memory on the base unit.

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. Highly accurate and reliable.

Certificaciones: CE marked. RoHS compliant. Traceable to NIST for accuracy. Multi-point calibration on an individually-numbered Traceable® certificate which assures accuracy from an 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.

Información para pedidos: Units are supplied with stainless steel probe/probes, universal AC adaptor, wall mount, Velcro®, magnetic strips, batteries, and an ISO 17025 Traceable® Certificate.
