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 a cellular network.

Four models are available:

  • The compact rugged TR41A model comes with a built-in sensor, offers our best waterproof rating (IP67),and is operable in a wide range of environments (-40 to 80°C).
  • The TR42A model features an external sensor for the quick response and can be connected to a variety of sensors for measuring temperatures from -60 to 155°C. The body itself has an IP64 rating and can be used in environments of -40 to 80°C.
  • The TR45 model is a versatile one-channel temperature logger that can be connected to a Pt100 sensor or to a variety of thermocouple types (K, J, T, S, R). It is possible to measure and record temperature in a wide range from -199 to 1760°C.
  • 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.

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.

*1: In the case of a 4-wire sensor, one wire will be left unused

*2: Battery life varies depending upon multiple factors including ambient temperature, recording interval, usage of applications, and battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.

*3: Estimated battery life when recording data at an interval of more than 10 seconds and displaying a graph in the app once a day

*4: This is the waterproof capacity of the data logger with the sensor connected. Note that the temperature-humidity sensor is not water resistant. The specifications listed above are subject to change without notice.
