Summit Appliance Portable Data Logger Description
Accucold offers a range of user-friendly options for versatile and reliable temperature logging in a variety of applications.
The Summit Appliance DLSA11 Portable Data Logger is a standalone temperature logger ideal for use when transporting items that need to be monitored. The compact size makes it easy to place in the logged area without compromising storage capacity. The Summit Appliance DLSA11 Portable Data Logger includes an LCD screen with a digital display of the temperature to the nearest tenth of a degree, as recommended by the CDC for vaccine storage. You can also view the highest and lowest temperature during the recording period, as well as the average temperature and mean kinetic temperature (a simplified way of showing the overall effect of temperature fluctuation during the recording period). This unit includes a protective transparent case that allows you to view the data without disrupting recording. The DLSA11CAL is calibrated to NIST standards in Accucold’s ISO/IEC 17025:2017 accredited laboratory. It ships with a calibration certificate for your facility’s records.
Designed for use with Windows-based platforms, the Summit Appliance DLSA11 Portable Data Logger includes downloadable software that is easy to program to your specific needs. Users can set the recording interval from every 10 seconds to 24 hours and specify whether to display the temperature in Celsius or Fahrenheit. Users can also choose to set a minimum/maximum temperature alarm that will show a visual indicator alert if the temperature goes out of range. These readings will be color-coded in the data exports for easy analysis. The logger offers an accuracy range of .5ºC in the temperature range of -20 to 40ºC, and 1ºC outside of this range. It records all data to the internal USB drive and can hold up to 32,000 readings. When you’re ready to view your data, simply plug your logger into your computer and open the software in Excel, Adobe Illustrator, or PDF format. From there, you can easily view and export the data in graphical or tabular form. Logging software is included in the downloads on this page.
This portable logger is powered by a replaceable lithium battery. The LCD screen will display a low battery alert as a warning. While battery life varies according to usage, the DLSA11’s battery is generally specified for 12 months when used to record in 15 minute intervals at an average temperature of 25ºC.

Product FAQ
What is the DLSA11 Portable Data Logger and what’s it used for?
The DLSA11 is a compact, battery-powered temperature data logger designed for transport and storage monitoring. Its portable size allows placement in cold-chain containers or storage units to accurately track temperature data.
What are the key technical specifications?
Key specifications include: accuracy of ±0.5 °C in the range -20 °C to 40 °C (±1 °C outside that range), capacity for up to 32,000 readings, user-set logging interval (10 s to 24 h), built-in USB interface supporting data export in Excel, PDF, or Illustrator formats, and an LCD display showing current, high/low, average, and mean kinetic temperature values.
How is it powered and what is the expected battery life?
It uses a replaceable 3.6 V lithium battery. Under typical conditions (15-minute interval at ~25 °C) the battery life is specified at approximately 12 months. The LCD will display a low-battery indicator when replacement is required.
Does it include calibration and documentation for compliance?
Yes. The DLSA11 is supplied with a calibration certificate from an ISO/IEC 17025:2017 accredited lab, supporting regulatory documentation for your facility.
What environments or temperature ranges can it monitor?
It is designed for a broad range of applications including transport and storage. Accurate to ±0.5 °C between -20 °C and 40 °C, and ±1 °C outside that range, it is appropriate for monitoring vaccines, pharmaceuticals, lab samples, and similar temperature-sensitive items.
Shipping FAQ
How long does shipping take after I place my order?
Orders typically ship within 1–2 business days after order processing. Delivery time depends on your location and selected shipping method.
Do you ship internationally and what are the restrictions?
Yes — international shipping is available. Customers outside the domestic region are responsible for import duties, customs fees, or compliance charges in their own country.
How will I track my package once it’s shipped?
After shipment you’ll receive a confirmation email including tracking information. Use that link to monitor delivery status in real time.
What packaging is used to protect the logger during transit?
The DLSA11 ships in protective packaging including a transparent protective case to guard against transit shock, temperature extremes, and handling damage.
What if my shipment is delayed or gets lost?
If delivery is delayed beyond the estimated timeframe or a shipment goes missing, contact our support team with your order number and tracking details. We will liaise with the carrier to locate or replace the shipment according to our shipping policy.
Application FAQ
How do I set up and program the logger for my application?
Install the included Windows-based software, set your desired logging interval (from 10 seconds to 24 hours), choose temperature units (°C or °F), and configure high/low alarm thresholds. Place the logger in your target environment and let it record. Later, plug it into a USB port to export the data.
Which export formats are supported and how do I interpret the data?
Logged data can be exported in Excel (.xls/.xlsx), PDF, or graphical format compatible with Adobe Illustrator. Out-of-range readings are color-coded in export reports for easy identification.
Can the logger be used with systems or workflows from other brands?
Yes. The logger’s USB interface and standard export formats make it compatible with existing documentation systems, quality control workflows, or cold-chain monitoring setups in your facility.
How do I use it during transportation of temperature-sensitive items?
Place the logger inside the transport container or adjacent to the item being monitored such as vaccines or pharmaceuticals. The compact form factor means minimal intrusion into usable space. On arrival, plug into a computer and review logged data for temperature excursions and compliance.
What should I do if temperatures go outside the set limits during recording?
If the LCD shows the visual alarm indicator or later in the export you see out-of-range data, document the excursion event, isolate any affected product if required, and review the exported data for traceability. If excursions are frequent, consider replacing or recalibrating the logger.
