The TR-73U USB Temperature Humidity Pressure Data Logger has three channels: one temperature, one humidity, and one barometric pressure. This compact, lightweight model has been designed with low energy consumption for longer battery life; coupled with its easy-to-use software and USB connection makes this product 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.
