Announcing our New Network Thermo Recorder: TR-700W Series

Date Issued: November 01, 2012

T&D Corporation is proud to announce the release of our new network connected TR-700W Series Temp/Humidity Data Loggers.
The TR-700W Series Data Loggers are designed with an onboard server making it capable of transmitting data across a network without a PC connection.
TR-700W data loggers enable the user to monitor current readings, collect recorded data, and have warning notifications sent from the logger via the Internet or LAN.

Furthermore, our T&D WebStorage Service makes it possible to gather, check and share data across the Internet.

*T&D WebStorage Service is an online service provided free of charge by T&D Corporation.

*1: When used in environments where temperature and humidity are over the values of 50°C 75%, 60°C 50%, 70°C 35%, and 80°C 25%, sensor hysteresis may fluctuate by values greater than ±1.5%RH. Under certain circumstances, it may take some time to return to normal measurement capability.

*2: The supplied lithium battery is for data backup during power failure and for emergency use only. Note that network communication cannot occur when using the battery only.

*3: Battery life varies depending upon the ambient temperature and the 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.
