LogTag® UTREL-16F – Low Temperature Data Logger with External Probe

The LogTag® UTREL-16F is a high-performance temperature data logger designed for precise monitoring in low-temperature environments. Compatible with the ST10 external probe, this device is perfect for applications requiring external sensor placement, such as cold storage, pharmaceuticals, and laboratories.

Key Features:

• External Probe Compatibility: Works seamlessly with the ST10 external probe for accurate temperature measurements in hard-to-reach or sensitive locations.

• Clear LCD Display: Shows recording status, current temperature, alarm status (up to six configurable alarms), and duration of any temperature excursions for instant monitoring.

• Integrated USB Connector: Easily connect the UTREL-16F to a computer via the built-in USB plug to generate detailed PDF reports automatically — no extra accessories or proprietary software required.

• Advanced Data Analysis: Generates encrypted data files compatible with LogTag Analyzer® software for in-depth reporting and data management.

• Recommended Buffering: For temperatures below -40ºC, use with silica sand in the buffer assembly (silica sand and buffer bottle sold separately).

• Durable and Reliable: Ideal for cold chain logistics and temperature-sensitive storage applications.

Important Notes:

• Buffer bottle and silica sand are not included with the logger.

• The ST10M-15 external probe is designed for use with the buffer bottle for optimal performance in ultra-low temperatures.
