Traceable® 6427TR Excursion‑Trac™ Datalogging Low‑Temp Thermometer; 2 Stainless‑Steel Probes
This Traceable® Excursion‑Trac™ Datalogging Low‑Temp Thermometer provides continuous monitoring for ultra‑low freezers and cold‑storage environments. A rolling memory 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 two stainless‑steel probes are designed for low‑temperature applications and connect via microcables that allow 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 by an A2LA‑accredited ISO/IEC 17025 laboratory.
