Access Wide Range Temperature Data Anytime from Anywhere
Model: TR71A2
- The TR71A2 with two sensor connections can measure temperatures from -60 up to 155℃.
- The wide range of optional sensors provides increased measurement flexibility.
- The LCD screen allows the simultaneous display of either the current values of two channels, the highest and lowest values of channel 1, or the highest and lowest values of channel 2.
- The ALM icon on the LCD alerts the user of the occurrence of an alarm.
- Use the wireless LAN feature (compatible with the enterprise communication) to auto-upload data to the cloud for anytime anywhere access and receive warning notifications. By using Bluetooth or USB, you can configure device settings, generate reports, download data, and view the uploaded data.
- A USB cable (option US-15C) is required to connect the device to a PC.
Model: TR75A2
The TR75A2 is a temperature logger with two thermocouple (K, J, T, E, S, R) sensor connections. It is capable of measuring temperatures ranging from -199 to 1760°C, and can be used in very high temperatures such as in a plant furnace or in deep freezers where temperatures reach very low levels.
Functional buttons on the device allow you to make settings and start/stop recording. Use the wireless LAN feature (compatible with the enterprise communication) to auto-upload data to the cloud for anytime anywhere access and receive warning notifications. By using Bluetooth or USB, you can configure device settings, generate reports, download data, and view the uploaded data. You can download the recorded data and change the device settings on a PC via USB Connection. A USB cable (option US-15C) is required to connect the device to a PC.
The software application used with the TR75A2 has a "Vaccine Mode", which meets or exceeds CDC requirements for VFC, and is suitable for monitoring and recording vaccine temperatures. TR75A2 is useful not only in pharmaceutical and medical reseach labs, hospitals, but also in factories and other facilities.
Features
The TR71A2 and TR75A2 use a wireless LAN access point to auto-upload recorded data and warning notifications to our free-of-charge cloud-based “T&D WebStorage Service”. You can download data and configure device settings using our dedicated app "TR7 for Windows (for Windows)" or "T&D Thermo (for smartphone / tablet)". By using our Windows software “T&D Graph”, you can easily view and analyze data from a PC.

- Products do not include thermocouple sensors. Compatible wire sizes are as follows. Single Wire : Ø0.32 to Ø0.65 mm (AWG 28 - 22),Twisted Wire : 0.08 to 0.32 mm2 (AWG 28 - 22),Ø0.12 mm or more in diameter, and Stripping Length : 9 to 10 mm.
- When Auto Upload is used frequently, the measurement of the internal sensor may rise by around 0.3 °C. When using external power, the data logger itself generates heat and the internal sensor will report a temperature much higher than ambient; we recommend using an external temperature sensor in this case.
- When continually used in environments with temperatures above 60 °C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20 °C.
- Vaccine mode complies with the CDC (Centers for Disease Control and Prevention) requirements for vaccine management.
- When using EAP-PEAP, server certificate verification using the CA certificate is not available.
- Client function. Only HTTP proxy is supported (not HTTPS).
- The optional AC adaptor “AD-05A2” (Type A Plug) can be used in the USA and Canada, and “AD-05C2” (Type C Plug) in Europe. For usage in other countries, please contact your local distributor.
- Battery life in the table above is for two AA Alkaline type batteries, and varies depending upon multiple factors including frequency of communication, network environment, ambient temperature, recording interval, 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.
- Free software download and information on OS compatibility is available on the Software page of our website at https://tandd.com/software/
- TR7 for Windows requires a PC with Bluetooth capability (4.0 or above) or a USB communication cable (available as option: US-15C). The specifications listed above are subject to change without notice.
