Accucold DL2BKIT USB Digital Data Logger (DDL), NIST Calibrated Temperature Monitoring System for Refrigerators and Freezers with USB Data Export and Alarm Functions

The Accucold DL2BKIT is a professional-grade USB digital data logger (DDL) engineered for healthcare facilities, pharmacies, laboratories, clinics, vaccine storage centers, and medical refrigeration applications requiring precise temperature monitoring and regulatory compliance. Designed for use with virtually any refrigerator or freezer, this unit provides accurate logging, real-time monitoring, and reliable audit-ready recordkeeping for vaccines, biologics, medications, and pharmaceuticals.

The DL2BKIT features a large LED-illuminated LCD screen that simultaneously displays current, minimum, and maximum temperatures to the nearest tenth of a degree, meeting CDC recommendations for vaccine storage monitoring. The display can be viewed in either Celsius or Fahrenheit and is positioned at a slight angle for improved readability.

This unit is NIST calibrated in Accucold’s ISO/IEC 17025:2017 accredited laboratory and includes a calibration certificate for compliance documentation. The external temperature sensor is enclosed inside a glycol-filled bottle, protecting it from rapid temperature fluctuations caused by door openings and providing more accurate product-simulated readings rather than ambient air measurements.

Users can fully customize the logging interval from 10 seconds to 240 minutes depending on monitoring requirements. The internal memory stores up to 32,000 data groups, while the included 4GB USB flash drive allows expanded storage and simple transfer of data to PC or Mac systems using Microsoft Excel or any CSV-compatible software.

The DL2BKIT includes programmable high/low audible and visual alarms with alarm delay and alarm hysteresis settings to reduce false alerts and unnecessary alarm chattering. Password protection ensures only authorized personnel can adjust settings, supporting secure facility compliance protocols.

Powered by the included 12V DC adapter, the unit also includes a rechargeable lithium-ion backup battery capable of recording for up to 8 hours during power outages. Its durable steel housing and included Velcro mounting strips provide secure installation and long-term reliability.

Designed for a temperature range of -45°C to +120°C (-49°F to +248°F), the DL2BKIT meets CDC, VFC, and VFA recommendations for reliable temperature logging and vaccine storage compliance.
