-200℃ ~ +70℃

ILOG-G30 is a single-use 4G real-time temperature and humidity data logger for one-way cold chain shipments. It monitors temperature, humidity, location, route and light throughout transportation, while the cloud platform provides configurable email and SMS alerts. The TFT LCD enables quick on-device checks, and 22,000 locally stored data points with automatic USB PDF reporting provide reliable backup documentation.
-30℃ ~ +70℃

CLOG-90 is a single-use, probeless USB temperature data logger designed for dry ice and ultra-low temperature shipments from -90°C to +70°C. The complete logger can be placed inside the monitored package without an external probe. Its LCD provides immediate access to the current temperature, alarm status, maximum, minimum and average readings. At destination, connect CLOG-90 to a computer USB port to generate an encrypted PDF report automatically, with no dedicated reader or software required.
-90℃ ~ +70℃

SLOG-200E is a reusable ultra-low temperature data logger with an external PT100 probe for monitoring temperatures from -200°C to +70°C. Designed for cryogenic storage, ultra-low temperature freezers, laboratories and deep-frozen cold chains, it stores up to 52,000 readings and displays key monitoring information on its LCD. After monitoring, connect the logger to a computer USB port to generate an encrypted PDF report automatically. A replaceable battery supports repeated and long-duration use.

Guides, compliance, and field insights for cold chain teams.

A data logger records what happened. Real-time monitoring tells you as it happens. Learn when each architecture makes sense for cold chain shipments.

Cold-chain failures often begin with routine operations rather than dramatic equipment breakdowns. Here are five common blind spots and what better monitoring can reveal.

Yes. Cooling can restore the measured temperature before delivery. Learn why excursion duration, timing and full temperature history matter more than the final reading alone.
