Utilise your existing Wi-Fi network to create a wireless temperature data logging and alarm monitoring system with the TR72A-S, a humidity and temperature data logger.

Interface with your TR72A-S in the field using the built-in Bluetooth functionality and an iOS or Android compatible mobile device.

This battery or mains powered data logger displays, collects and stores temperature data measured by an interchangeable sensor fitted to the end of 1M of cable. Historical data can be extracted to a PC using the integral USB connector or linked in real-time data via the Wi-Fi module to a mobile device running iOS, Android or that hosts an internet connection and browser.


  • Wi-Fi (WLAN)

  • Bluetooth
  • Online using free cloud storage utility

Mount your TR72A-S data logger outside of an incubator or humidity/temperature critical environment and feed the probed cable into the desired monitoring location, repeat for additional monitoring locations across different floors of a building or even in different geographical locations with all data sent back to a central location via the TandD cloud utility called ‘Webstorage-service’

Unlike alternatives offered by LS and our competitors, TandD deliver free application and cloud storage utilities with no contracts or restrictions.
