Introduction to Dry Ice Monitoring

Monitoring in dry ice environments is a vital process for industries such as pharmaceuticals, food, and logistics, where maintaining strict control is essential for product safety and quality. Dry ice, as a powerful cooling agent, is commonly used to keep sensitive products at ultra-low temperatures during storage and transportation. However, the effectiveness of dry ice depends on precise temperature monitoring throughout the entire process.

Dry ice data loggers are specifically designed to operate in temperature environments ranging from -80°C to +40°C (-112°F to +104°F), making them ideal for dry ice shipments and other ultra-low temperature applications. These devices provide immediate visual confirmation of conditions, allowing users to quickly assess whether products have remained within safe limits. With features such as easily configured settings, delayed start options, customizable intervals, and clear alarm status indicators, these data loggers streamline the temperature monitoring process. Companion software, like LogTag Analyzer, further enhances usability by enabling users to configure devices, download data, and analyze readings efficiently. This combination of advanced technology and user-friendly design ensures that products remain protected throughout their journey in challenging temperature environments.

Key Features of the Device

A dry ice temperature data logger stands out for its high accuracy and robust performance in low conditions. One of its most notable features is the ability to provide immediate indication of status through visual alerts. The red alert indicator instantly notifies users if any readings fall outside the configured limits, while the green OK indicator offers visual confirmation that the unit is operating within the desired range. This immediate feedback is crucial for maintaining the integrity of sensitive shipments.

It operates across -90℃ to 70℃, ensuring suitability for both ultra-low and moderately cold environments. With an impressive accuracy of ±0.5℃ and a fine resolution of 0.1℃, the device provides precise readings essential for sensitive applications.

The logger’s memory can store up to 35,000 readings, supporting frequent temperature sampling intervals and long-term monitoring. Users can configure the device to start logging at a specific time, with a flexible interval that can be set anywhere from 1 minute to 24 hours, depending on the requirements of the shipment or storage process. Powered by a 3.6V Lithium battery, the data logger offers up to 120 days of operation, making it ideal for extended transportation or storage periods. Compliance with CE, RoHS, and EN12830 standards ensures the device meets industry regulations for cold chain monitoring, providing peace of mind for users in regulated industries.

Applications and Benefits

Data loggers are indispensable tools for a variety of industries that require strict control, such as pharmaceuticals, food, and logistics. These devices are particularly beneficial for monitoring shipments, where maintaining low temps is critical to preserving product quality and safety. The ability to set frequent temperature sampling intervals allows for detailed tracking of fluctuations, ensuring that any deviations are quickly detected and addressed.

Immediate visual confirmation of conditions, provided by the logger’s alert indicators, enables users to take prompt action if it move outside acceptable areas. This feature is especially valuable during transportation, where quick decisions can prevent product loss. The logger’s suitability for low applications makes it ideal for monitoring frozen food, vaccines, and other sensitive products during storage and transit. Its robust design and configurable settings ensure reliable performance in a wide area of conditions, from sea and air freight to distribution centers and cold storage facilities. By providing accurate, real-time monitoring and comprehensive records, these loggers help companies comply with industry standards, protect valuable shipments, and maintain the highest levels of product integrity.
