NOTE: The DL2BKIT is for aftermarket installation.  It ships in a single box with the following items included: a 4GB USB flash drive, a power adapter, a rechargeable battery, an external temperature sensor encased in a bottle filled with glycol, and a NIST certified calibration certificate. If you want this data logger installed on a Summit or Accucold refrigerator, order the DL2B option with your unit. Contact your sales representative for details and pricing on pre-installation.

Accucold brings true convenience and trusted reliability to temperature logging with the DL2BKIT digital data logger (DDL). With a NIST calibrated probe and large display, this data logger offers all the features needed for accurate and convenient temperature monitoring.

Designed for use with virtually any refrigerator or freezer, the DL2BKIT lets you set your own recording intervals (anywhere between 10 seconds to 240 minutes) for logging that meets your specific needs. The digital data logger can store up to 32,000 groups of data through its internal memory, or up to 4GB using the included USB flash drive. When you're ready to review the temperature data, simply plug the flash drive into your PC or Mac and transfer the data using Microsoft Excel or any .CSV compatible program. The unit is also compatible with a USB 3.0 extension cable for easy data transfer. This DDL offers accurate logging with a measurement uncertainty of ±0.09ºC, conforming to the CDC's guidelines for calibration.

The LED illuminated LCD screen features a large simultaneous readout of the current, minimum, and maximum temperature to the nearest tenth of a degree, as recommended by the CDC for vaccine storage. The default readout is set to display in Celsius, but can be switched to Fahrenheit in just a few steps. A high/low temperature alarm sounds and flashes when the temperature rises above or falls below the user-set range.

The DL2BKIT is powered by a 12V DC power adapter included with your unit. A rechargeable lithium battery is also included to allow you to record up to 8 hours of data in the event of a power failure. The temperature sensor is enclosed in a glycol-filled bottle to protect it from rapid changes when the door is opened, better simulating the temperature of stored contents instead of air temperature. This item is NIST calibrated in Accucold's ISO/IEC 17025:2017 accredited laboratory and ships with a calibration certificate for your records. For added security, the DL2BKIT is password protected to ensure only authorized staff can adjust the logger's settings. 

The DL2BKIT comes in a durable steel housing. The screen is set at a slight angle, making it easy to view the temperature at a glance. This logger can also be ordered pre-installed on any Summit or Accucold refrigerator/freezer using the "DL2B" upgrade option. It is designed to measure a temperature range of -45º to +120ºC (-49º to +248ºF).
With its flexible programming capabilities and user-friendly interface, the DL2BKIT creates an easy and reliable solution to temperature logging. By providing a detailed and accurate temperature record, this DDL meets CDC and VFC recommendations for logging and monitoring vaccine storage.
