Data loggers with infrared communications

TandD Corp has introduced its infrared communication type data loggers.

The TR-71Ui (temperature) and TR-72Ui (temperature and humidity) models offer the features of the original TR-7U Series Data Loggers plus full functioning infrared communication.

This function makes it possible to use infrared data collector TR-57DCi to download and save the data recorded by the TR-7Ui series loggers, releasing the user from the burden of physically gathering the loggers to collect data.

The data collected and saved in the TR-57DCi can then be easily viewed in graph form on the spot or viewed on a PC, which broadens the range of use.

Using the internal sensor, the temperature range is -10°C to 60°C, while with an external sensor the temperature range is -40°C to 110°C (0°C to 50°C for the TR-72Ui).

The humidity range on the TR-72Ui is from 10 to 95%RH.

Data can be downloaded to a PC with a USB cable.

Both units operate on an AA battery with a life expectancy of one year or seven months if the infrared communications has been enabled.
