This 2-Channel temperature and humidity logger enables data collection and management using dedicated mobile device applications.
Great for transport, storage, limited-access areas, residential and office buildings
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.
The all-in-one sensor for TR43A has a temperature measurement range of 0-55°C and can measure humidity from 10 to 95％RH. The body itself has an IP64 rating* and can be used in environments of -40 to 80°C.
*Note that the temperature-humidity sensor is not water resistant.
Special Features
- With the compact rugged design and Bluetooth capability, the TR43A is easy to deploy and operate, suitable for tracking temperature and humidity in transport, in storage, in limited-access areas, as well as in residential and office buildings.
- The free mobile apps that let you access temperature/humidity data anytime from your smartphone or tablet over Bluetooth.
- “T&D Thermo” facilitates logger configuration and data collection using a Bluetooth connection. The data retrieved by the mobile device can be viewed in a graph, saved, output as a PDF report, and uploaded to the cloud-based T&D WebStorage Service.
- “TR4 Report” is a specialized mobile app for generating PDF reports for a specified time period. It allows you to create, print and share data reports in simple steps.
