Introduction to Temperature Data Loggers
Temperature data loggers are indispensable tools for organizations that need to monitor and record temperature data over extended periods. These devices are engineered to deliver accurate readings, making them essential for regulatory compliance in labs, medical, and industrial environments. By continuously tracking temperature ranges—from ultra-low to high temperatures—data loggers help ensure that sensitive products, such as vaccines, pharmaceuticals, and laboratory samples, are stored under optimal conditions. Whether used in refrigerators, freezers, or other controlled environments, temperature data loggers provide reliable records that support quality assurance, product safety, and peace of mind for users who must meet strict compliance standards.
Key Features of the UTREL-16
The UTREL-16 stands out as a robust and reliable data logger, purpose-built for monitoring a wide temperature range from -90°C to 40°C. Its large LCD display allows users to easily check current, minimum, and maximum temperatures at a glance, while audible alarms provide immediate notification of any temperature excursions. With the capacity to measure and store over 16,000 temperature readings, the UTREL-16 offers long-term monitoring and secure data storage. Users can conveniently download data either through dedicated software or as a report, streamlining keeping and compliance documentation. The device’s CDC-compliant design and ISO/IEC 17025 NIST traceable calibration ensure that it meets the highest standards for accuracy and reliability, making it an ideal choice for vaccine storage, lab monitoring, and any application where precise temperature control is critical.
