TR-7wf series data loggers for temperature and humidity from T&D Corporation automatically save current readings on T&D''s free of charge WebStorage Service via wireless LAN. This facilitates easy monitoring of current data, graphic displays and alerts as well as downloading of recorded data. Mobile access is also possible at any time from anywhere via the internet or the ThermoWeb app, which is available for iOS and Android. TR-7wf series data loggers are therefore ideal for use in public and industrial surroundings, where large areas or difficult to access spaces have to be monitored precisely.

The TR-71wf data loggers enable wide range measurement of temperatures from

- 40°C to 110°C. The TR-72wf, on the other hand, measures temperatures from 0°C to 55°C and humidity from 10 to 95 per cent relative humidity (RH). For customers who require a wider range of coverage, the TR-72wf-H measures temperatures from - 30°C to 80°C and humidity from 0 to 99 per cent RH.

The TR-7wf series can also connect via USB for setup and data download onto a computer when a wireless connection is not available. Power is supplied either with AA Alkaline or AA Ni-MH batteries. Battery life is about one and a half years, depending on the auto-upload interval and the usage of wireless LAN communication. If any disturbance should occur when the data loggers are in use, warning notifications can be sent via e-mail over the network. Furthermore, the ThermoWeb app also receives visual and acoustic warning signals.

If no access point is available, direct communication with ThermoWeb app installed mobile devices is possible.

Their high precision and wide range measurement facilities combined with their flexibility makes the TR-7wf data loggers ideal for use in industrial as well as public areas. They can be utilized, for example, in hospitals, museums, warehouses or subway trains for temperature and humidity management and also for humidity and heating control in housing.
