The TR-77Ui is our innovative 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.
Not only can recorded data be easily downloaded to a PC via USB communication, but it can also be collected from data loggers via infrared communication to our T&D Data Collector TR-57DCi (sold separately). The TR-57DCi enables the user to gather and check recorded data on the spot without having to manually gather the data loggers.
