Compact Rugged Temperature/Humidity Data Loggers with Bluetooth
The TR4A series enables data collection and management using dedicated mobile device applications.
Data recorded by the logger is sent to the mobile device via Bluetooth Low Energy, which can then be transferred to our free cloud-based "T&D WebStorage Service" using WiFi or cellular network.
Four models are available with an internal temperature sensor (TR41A), with an external temperature sensor (TR42A), with an external temperature-humidity sensor (TR43A), or with thermocouple/PT compatibility (TR45). Select one that suits your needs.
We offer mobile apps for Android and iOS smartphones and tablets free of charge: "T&D Thermo" for device setup, data download and graphing, and "TR4 Report" for creating PDF reports for a specified time period.
