Traceable® 6457TR Excursion‑Trac™ Datalogging Cryogenic Thermometer; 2 Stainless‑Steel Probes

Traceable® 6457TR Excursion‑Trac™ Datalogging Cryogenic Thermometer; 2 Stainless‑Steel Probes

This Traceable® Excursion‑Trac™ Datalogging Cryogenic Thermometer provides continuous ultra‑low‑temperature monitoring with a rolling memory that stores the most recent 525,600 temperature observations. The display simultaneously shows high, low, and current temperatures, and Smart‑Alarm™ alerts visually and audibly even if conditions return to the acceptable range. The included Pt RTD stainless‑steel probes are designed for cryogenic applications and connect by 120‑inch microcables that allow refrigerator or freezer doors to close on them. Logged data and alarm events can be downloaded by USB for documentation. Each unit is supplied with a NIST‑traceable calibration certificate issued at test points of –196, –80, 0, and 100 °C by an A2LA‑accredited ISO/IEC 17025 laboratory.
