Description
The TR75A2 WiFi & Bluetooth Thermocouple Data Logger
The TR75A2 is a temperature logger with two thermocouples (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 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 is required to connect the device to a PC and can be purchased as an add-on accessory.
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 research labs, and hospitals but also in factories and other facilities.
TR75A2 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 TR75A2 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.
