Temperature & Humidity Data Logger for Cold Chain Monitoring
Document temperature and relative humidity simultaneously during transport and storage.
The STRATUM ST-TH01 is a USB data logger designed to measure and record temperature and relative humidity across transport and storage operations. By documenting both parameters simultaneously, it provides objective environmental records that can support storage-condition assessment, logistics investigations and quality reviews.
Monitor temperature and humidity throughout transport and storage
The ST-TH01 records temperature and relative humidity to create an objective environmental record during transport and storage. In warehouses, cold storage facilities and international transit, monitoring both parameters provides additional visibility into the conditions encountered by temperature- and humidity-sensitive goods.
These records provide logistics and quality teams with documented data that can be reviewed when assessing environmental conditions or investigating a logistics or quality incident.
Why temperature and humidity monitoring matters
Temperature excursions are an important risk factor for sensitive cargo. Relative humidity provides additional environmental context that temperature measurements alone cannot provide.
Measuring both temperature and relative humidity helps document conditions associated with moisture exposure, humidity variations and condensation risk. The recorded data can support environmental analysis and help quality or logistics teams investigate the conditions encountered during transport or storage.

Simple monitoring from departure to destination
- Configure: Set the required measurement interval, recording duration, start delay and alarm thresholds according to the monitoring protocol.
- Activate: Start the logger using the designated activation procedure.
- Place with the shipment or in the monitored area: Position the logger according to the selected transport or storage monitoring protocol.
- Record temperature and humidity: The ST-TH01 measures and records temperature and relative humidity throughout the configured monitoring period.
- Connect through USB: At destination, connect the logger to a compatible computer to access the recorded information.
- Review the recorded data: Open the generated report and examine the documented environmental conditions.
This workflow provides senders, logistics providers and receivers with documented temperature and humidity records that can be reviewed after transport or storage.

Temperature and humidity monitoring across international supply chains
The ST-TH01 supports logistics operations that require simultaneous temperature and relative humidity monitoring.
Typical applications include food products, seafood and fisheries products, meat products, flowers, horticultural products, cold storage, warehousing and refrigerated logistics for temperature- and humidity-sensitive goods.
More than temperature monitoring
Temperature monitoring provides only part of the environmental picture. The ST-TH01 adds relative humidity data, providing additional context for transport and storage analysis.
Evaluating both metrics can help operational teams document temperature exposure, relative humidity exposure, storage environments and transport conditions when reviewing quality or logistics incidents.
Designed for professional cold chain requirements
The ST-TH01 is presented with the following validated conformity references: EN12830, CE, FCC and RoHS.
