The VL-1000-VLT Very Low Temperature data logger records and monitors temperatures as low as -90°C (-130°F) without need for external probes or wires.
Completely self-contained and self-powered, VL-1000-VLT data loggers can be placed directly into cold environments for shipping temperature studies, cold-chain validation, or for long-term unattended monitoring.
Simple to use, the unit can be deployed without need for drilling holes in expensive enclosures (in order to route external probes). In doing so, the data logger helps eliminate damaged seals and the possibility of warm air infiltration - thus assuring the highest possible accuracy of measurement results.
