Traceable® 6440TR Memory‑Loc Datalogging Thermometer with Glass Bottle Probe

Traceable® 6440TR Memory‑Loc Datalogging Thermometer with Glass Bottle Probe

The Traceable® 6440TR Memory‑Loc thermometer provides secure, high‑accuracy temperature monitoring with non‑overwrite datalogging designed for regulated environments. The unit captures over one million temperature data points and allows logging intervals from 1 minute to 24 hours. Memory‑Loc technology prevents data overwrite—logging stops automatically when storage is full, making this instrument ideal for 21 CFR 11 environments requiring secure, unalterable records. Each unit includes an individually numbered NIST‑traceable certificate from an A2LA‑accredited calibration laboratory, ensuring compliance with ISO/IEC 17025 calibration standards.

More About This Item

Easily monitor temperatures overnight or for extended periods using the Memory‑Loc datalogging thermometer. Select logging intervals from 1 minute to 24 hours to capture over one million temperature data points. The datalogger automatically stops recording when storage is full and will not overwrite existing data—ideal for 21 CFR 11 environments requiring secure, non‑modifiable records.

Set high and low alarms in 1° increments. Alarm tracking stores up to 10 alarm events, including timestamps for when the alarm occurred and when the unit returned to normal range. Visual indicators include flashing LCD segments, and audible alerts provide clear notification.

Data transfers via USB in CSV format—no software required. The unit continues recording while downloading. Status indicators include low battery, memory full, USB transfer active, and alarm state. The 10‑ft microcable allows doors to close on the cable without damage. Mount the unit using hook‑and‑loop strips, magnetic strips, wall‑mount slots, or the flip‑open stand.
