The TR-75nw is a temperature logger with two available thermocouple (K, J, T, E, S, R) sensor connections and can measure from -199 to 1760°C.

Functional buttons on the device allow you to make settings and start/stop recording. Use the Ethernet connection to auto-upload data to the cloud for anytime anywhere access and get warning notices. Connect to a PC with a USB cable to download recorded data, create reports and make setting changes.

It is perfect for use in ultra high temperatures such as in a plant furnace or in deep freezers where temperatures reach ultra low levels.


Note: We do not stock thermocouple sensors; please purchase a compatible sensor.

Benefit

The TR-75nw uses a wired LAN connection to auto-upload recorded data and warning notifications to our free cloud-based “T&D WebStorage Service” or your Windows PC running the "T&D Data Server" software. Use our mobile app “T&D Thermo” to check data from your smartphone or tablet. To make settings from and download data via USB to a PC, use our Windows software “TR7 for Windows”. Our Windows software “T&D Graph” makes it easy to view and analyze data from your PC.

AA Alkaline Battery LR6 x 2, Registration Code Label, USB Mini-B Cable US-15C, Manual Set (Warranty Included)

*1: We do not handle the sale of 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, Stripping Length : 9 to 10 mm

*2: 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 recom- mend 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 can- not be measured at temperatures below -20 °C.

*4: HTTP client. Proxy supported.

*5: When using PoE, use of STP (shielded) cables may cause PoE failure or device malfunction. We strongly recommend using UTP cables.

*6: 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.

*7: -10 to 45°C when using external power.
