Description

The TandD TR71A2 Wireless Bluetooth Temperature Data Logger

The TR71A2 with two sensor connections can measure temperatures from -60°C up to 155°C. The wide range of optional sensors provides increased measurement flexibility. The LCD screen allows the simultaneous display of 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 screen alerts the user of the occurrence of an alarm.

Use the wireless LAN feature (compatible with Enterprise communication) to auto-upload data to the cloud for any time, anywhere access and receive warning notifications. You can configure device settings, generate reports, download data, and view the uploaded data using Bluetooth or USB. A USB cable is not included and can be purchased as an add-on accessory.

TR71A2 Operational Differences by Measurement Mode

Normal Mode Vaccine Mode
Max/Min Values Max/Min temperature reading since the start of recording or reset (via buttons or software/app) Max/Min recorded value since the start of recording or reset (via buttons or software/app)
Warning Judgment Time 30 sec to 60 min (9 selections)
A warning will be issued when a measurement exceeds the set threshold value or a sensor error occurs for longer than the set judgment time.		 0 sec.
If a recorded value exceeds the set threshold value or if a sensor error occurs, a warning will be issued.
Warning Display [ALM] Icon Warning alarms for exceeding a set upper and lower limit and for sensor errors will both disappear when the warning condition is resolved. Warning alarms for exceeding a set upper and lower limit will not disappear even after a value returns to within the threshold range. Warning alarms for sensor errors will disappear upon return to normal.

The TR71A2 uses a wireless LAN access point to auto-upload recorded data and warning notifications to TandD’s free-of-charge cloud-based “T&D WebStorage Service”. You can download data and configure device settings using TandD’s dedicated app “TR7 for Windows (for Windows)” or “T&D Thermo (for smartphone / tablet)“. By using their Windows software “T&D Graph”, you can easily view and analyze data from a PC.

*1: 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.
*3: 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.
*4: Vaccine mode complies with the CDC (Centers for Disease Control and Prevention) requirements for vaccine management. *5: When using EAP-PEAP, server certificate verification using the CA certificate is not available.
*6: Client function. Only HTTP proxy is supported (not HTTPS).
*7: 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.
*8: 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.
*9: Free software download and information on OS compatibility is available on the Software page of our website at https://tandd.com/software/.
*10: 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.
