Product information
The TR-71nw is a temperature data logger that can monitor two temperature zones, while the TR-72nw is a temperature/humidity logger. By using T&D WebStorage Service, a cloud service provided by T&D free of charge, it is possible to access stored data anytime from anywhere.
Power Over Ethernet: PoE IEEE 802.3af (TR-71nw or TR-72nw only)
Meets or exceeds CDC requirements for VFC plus automated record keeping and real time monitoring.

-
*1：For TR-71wf: When wireless LAN communication is used frequently, the measurement of the internal sensor may rise by around 0.3°C.
For TR-71wf and TR-71nw: 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. - *2: The WPS feature is not available when WEP(64bit/128bit) or WPA-PSK(TKIP) is selected in Access Point Settings. If you wish to use the WPS feature, please select WPA2-PSK(AES) or disable wireless security.
- *3: HTTP client. Proxy supported (for firmware version 1.05 or above for TR-7wf).
- *4: When using external power, the internal temperature of the logger rises.
- *5: Battery life varies depending upon multiple factors including frequency of communication, LAN 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.
- *6: Approx. 10 days when Auto-upload Interval is 1 min, 1 yr when 1 hr, 1.5 yrs when 12 hrs or more.
- *7: -10 to 45°C when using external power. (for TR-7nw)
- *8: Software is not included in the package, but can be downloaded free of charge from tandd.com.
- *9: For installation, it is necessary to have Administrator (Computer Administrator) rights.
- *10: We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed.

This range hood looks amazing above our island cooktop. The LED lighting is super bright and the 3-speed fan works like a charm. Installation was straightforward, even for a DIYer
This comforter is the softest thing I’ve ever owned. It’s like sleeping in a cloud. Keeps me warm without overheating — perfect for year-round use.
These curtains completely changed the feel of our boys room. They drape beautifully, block just the right amount of light, and were super easy to install. Highly recommend!
The matte black sink we purchased for our powder room is absolutely stunning. Everyone who visits asks where we got it. It adds a modern edge and ties the whole room together
I usually struggle to find dresses that feel both stylish and comfortable, but this one nailed it. Soft fabric, perfect length, and I felt confident wearing it all day. Worth every penny.
The coffee table we ordered is a total showstopper — solid wood, beautiful finish, and just the right size for our family. Assembly was simple and everything arrived in perfect shape
I ordered a few area rugs and some peel-and-stick wallpaper. The patterns are gorgeous and the materials feel premium. I’ve already recommended this store to three of my friends!
