HACCP Refrigeration Temperature Log — Free PDF

Yes. Devices such as the TempTrail series automatically produce a PDF report and CSV file when connected via USB, with no external software or drivers required. This provides a ready-to-file HACCP compliance record for refrigeration monitoring without added software licensing costs.

Standard models cover -30°C to +70°C (-22°F to +158°F), suitable for typical refrigerated and frozen storage. Ultra-low variants extend down to -85°C for cryogenic and dry ice applications, covering the full range needed for pharmaceutical and food cold chain monitoring.

Single-use loggers are low-cost, disposable devices intended for one shipment or monitoring cycle, typically powered by a coin cell battery with a preset logging interval. Multi-use loggers have a replaceable battery, user-configurable alarms and intervals, and can be redeployed repeatedly, making them more cost-effective for recurring warehouse or facility monitoring.

Yes. Most models offer temperature accuracy of ±0.2°C to ±0.3°C with 0.1°C resolution, and store up to 32,000 data points. Combined with FDA 21 CFR Part 11 compliant, tamper-evident PDF reporting, they meet documentation standards expected in FDA and HACCP-based audits.

Yes. Dual-parameter loggers track both temperature (-30°C to +70°C) and relative humidity (0-100% RH) simultaneously, which is useful for refrigerated storage of humidity-sensitive goods like produce, dairy, and floral products, where both readings affect product quality and compliance.

Recording duration depends on the logging interval and model. At a standard 10-minute interval, single-use loggers can run up to 220 days, while multi-use models offer user-configurable intervals with 32,000 data point capacity, allowing extended monitoring in refrigerated storage or long-haul shipments.
