Traceable® 6409TR High‑Accuracy Refrigerator/Freezer Digital RTD Thermometer; 1 Bullet Probe

Traceable® 6409TR High‑Accuracy Refrigerator/Freezer Digital RTD Thermometer; 1 Bullet Probe

The Traceable® High‑Accuracy Refrigerator/Freezer RTD Thermometer provides exceptional precision for monitoring critical cold‑storage environments. Designed for vaccine storage, pharmaceuticals, and laboratory samples, the instrument uses an RTD sensor to deliver ±0.1 °C accuracy with 0.01° resolution. A three‑line LCD simultaneously displays current, minimum, and maximum temperatures, while onboard memory stores hourly and daily MIN/MAX data for up to 31 days. A NIST‑traceable calibration certificate ensures compliance in regulated applications.
