T&D Temp/Humidity Data Logger

Code : TR-71U, TR-72U
Brand : T&D

TR-71U/TR-72U Thermo Recorders are data loggers capable of measuring, displaying and recording temperature and humidity data. TR-71U has two temperature channels and TR-72U has one temperature and one humidity channel. These compact, lightweight models are designed with low energy consumption for longer battery life. In addition, the easy-to-use software and USB connection make this series the foundation of our Thermo Recorder line.

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.
