CLOG-90

Probeless Monitoring for Dry Ice Shipments

• CLOG-90 is a single-use USB temperature data logger developed for dry ice, deep-frozen and ultra-low temperature shipments from -90°C to +70°C.

• Unlike external-probe systems, the complete logger can be placed directly inside the monitored package. Its built-in sensors record the conditions experienced close to the product throughout transportation.

Key Features：

Direct Placement in Ultra-Low Temperature Packaging

• The probeless design allows CLOG-90 to travel inside dry ice and deep-frozen packaging without installing or routing an external temperature probe.

Instant Status on the LCD

• Check the current temperature, recording status and alarm result directly on the built-in display. After recording has stopped, users can also review maximum, minimum and average temperature information.

Encrypted PDF Report via USB

• At destination, connect CLOG-90 to a computer USB port to generate an encrypted PDF report automatically. No dedicated reader or specialized software is required to open the report.

Multiple Alarm Ranges

• Configure multiple temperature alarm ranges according to product stability requirements and the conditions expected during transportation.

Independent Offline Recording

• CLOG-90 records and stores temperature data without relying on cellular networks, Wi-Fi, Bluetooth or cloud connectivity.

Designed for One-Way Shipments

• The single-use format eliminates the need to retrieve and return the logger after delivery, making it suitable for international and one-way cold chain shipments.

Information Available on the LCD：

• Current temperature.

• Recording and stop status.

• Start-delay status.

• Normal or alarm result.

• High- or low-temperature alarm.

• Maximum temperature.

• Minimum temperature.

• Average temperature.

• Battery status.

Encrypted Shipment Report：

• After the monitored trip, the automatically generated PDF report provides a traceable record of the temperature conditions experienced during transportation.

• Complete temperature history.

• Temperature graph and recorded readings.

• Maximum, minimum and average temperature.

• Alarm and excursion information.

• Start and stop information.

• Device serial number and configuration.

• Encrypted PDF format for secure record keeping.

How It Works:

• Press and hold the green start button for three seconds.

• Confirm the recording symbol on the LCD.

• Place CLOG-90 inside the dry ice or ultra-low temperature shipment.

• At destination, review the current temperature and alarm status on the LCD.

• Press and hold the red stop button for three seconds.

• Connect the logger to a computer USB port.

• Open the automatically generated PDF report.

Applications:

• Dry ice pharmaceutical shipments.

• Vaccines and biological products.

• Clinical trial materials.

• Biological samples and laboratory materials.

• Cell, tissue and specimen transportation.

• Deep-frozen food and ingredients.

• Ultra-low temperature cold chain logistics.

CLOG-90 or an External-Probe Logger?

• Choose CLOG-90 when the complete logger must travel inside dry ice packaging together with the product. Its probeless design simplifies placement in one-way shipments and provides a direct record of the internal package temperature.

• Choose SLOG-200E when the logger body must remain outside an ultra-low temperature freezer, container or storage system while an external PT100 probe monitors the internal temperature.
