Calibrated Data Loggers

Data loggers are compact electronic devices that automatically record environmental parameters like temperature and humidity over time using internal sensors. They store readings in onboard memory and, once connected via USB, generate PDF or CSV reports for review, making them essential tools for cold chain monitoring, shipment validation, and regulatory compliance documentation.

Calibration involves comparing the logger's readings against a certified reference thermometer across multiple temperature points, then adjusting or documenting any deviation. Realog View devices are pre-calibrated at the factory with traceable certificates; for ongoing use, periodic recalibration against NIST-traceable standards is recommended to maintain FDA 21 CFR Part 11 compliant accuracy.

Single-use loggers are pre-configured, low-cost devices designed for one shipment or monitoring cycle before disposal, ideal for short trips. Multi-use loggers feature replaceable batteries and user-configurable logging intervals and alarms, allowing repeated deployment across multiple shipments or facility monitoring cycles, offering better long-term cost efficiency.

Realog View's TempTrail lineup spans an extensive range, from -85°C for cryogenic and dry ice applications up to +140°C for autoclave and oven validation. Standard cold chain models cover -30°C to +70°C, giving buyers flexibility to match the exact range required for their pharmaceutical, food, or industrial process.

Yes, most TempTrail models feature an IP67 waterproof rating, protecting against dust ingress and temporary submersion, while the HiTemp autoclave logger is IP68 rated for full submersion. This rugged sealing ensures reliable performance during wash-downs, wet transport conditions, and harsh industrial or cold chain environments.

No external software is required. TempTrail data loggers automatically generate PDF and CSV reports when connected via USB to a Windows PC with Adobe Reader 9.0 or higher, simplifying documentation review, sharing, and long-term record keeping for compliance and audit purposes.
