Types of Data Loggers for Import and Export Monitoring
When importing and exporting temperature-sensitive goods, selecting the right type of data logger is critical to ensure product integrity and regulatory compliance. Here are the main types of data loggers used in logistics and cold chain monitoring:
1. Single-Use (Disposable) Data Loggers
- Purpose: One-time shipments
- Common Use: Pharma exports, food shipments, vaccine transport
- Features:
– Cost-effective
– Automatic PDF reports
– No software required
- Ideal For: Exporters who don’t expect the logger to be returned
2. Reusable (Multi-Use) Data Loggers
- Purpose: Multiple shipments or long-term use
- Common Use: Internal distribution, importers with return logistics
- Features:
– Rechargeable or replaceable battery
– USB or Bluetooth connectivity
– Programmable logging intervals
- Ideal For: Companies with a reverse logistics system
3. Real-Time (GSM/GPRS) Data Loggers
- Purpose: Live tracking of temperature, location, and alerts
- Common Use: High-value pharma, biotech, or food shipments
- Features:
– SIM-enabled GPS & temperature tracking
– Alerts via SMS/email for temperature excursions
– Cloud storage of data
- Ideal For: Critical shipments needing 24/7 visibility
4. USB PDF Data Loggers
- Purpose: Simple plug-and-play reporting
- Common Use: General exports where regulatory report is needed
- Features:

- Ideal For: Importers/exporters who want fast, wireless access to data
6. Dry Ice / Ultra Low-Temperature Data Loggers
- Purpose: Monitor shipments stored at -80°C or in dry ice
- Common Use: Biotech, clinical trials, deep frozen goods
- Features:
– Tolerates extreme temperatures
– Highly accurate
- Ideal For: Laboratories, vaccine logistics, biotech exports
7. Humidity + Temperature Data Loggers
- Purpose: Dual monitoring of temperature and relative humidity
- Common Use: Electronics, art, sensitive chemicals
- Features:
– Records both RH% and °C/°F
- Ideal For: Moisture-sensitive imports/exports
Tip from Westcal: Choosing the right logger depends on shipment duration, product sensitivity, regulatory requirements, and whether you expect the logger to be returned.
