T&D Corporation is proud to announce that our new "High Precision Wide Range Temperature and Humidity Data Logger TR-77Ui" will be available from January 2010.

The TR-77Ui is our new temperature and humidity data logger designed to measure and record in a wider range with more precision than ever before. It reaches the high measurement accuracy of ±2.5%RH and can measure and record in the range of 0 to 99%RH ( at temperatures from -30 to 80°C).

The product is an all-in-one package that includes the data logger unit, sensor and software. Simply by connecting to a PC via a USB connection and carrying out a few easy steps, the measurement and recording of data can be started.
