Description
Specifications

Capable of measuring, displaying and recording temperature and humidity.

TR-72nw

The TR-72nw allows you to measure and record temperature from 0 to 55°C and humidity from 10 to 95%RH.

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 not only homes and offices but for warehouse and storage facilities.

The TR-72nw uses a wireless LAN access point 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 and use Bluetooth communication to make settings and download recorded data. To make settings from and download data via USB to a PC, use our Windows software “TR-7nw/nw-S for Windows”. Our Windows software “T&D Graph” makes it easy to view and analyze data from your PC.

TR-72nw-S

The TR-72nw-S allows you to measure and record with high precision temperature from -25 to 70°C and humidity from 0 to 99%RH.

It is perfect for situations where strict temperature and humidity control is required, such as when storing delicate items or in testing using constant temperature and humidity chambers.

The TR-72nw-S 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.

*1: Compatible wire sizes are as follows.

Single Wire : 0.32 to 0.65 (AWG 28 - 22),Twisted Wire : 0.08 to 0.32 (AWG 28 - 22), 0.12 or more in diameter, Stripping Length : 9 to 10

*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 external power, the internal temperature of the logger rises.

*6: 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.

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