Japan company TandD temperature and humidity recorder with low power consumption and high accuracy. It is a highly reliable network temperature and humidity recorder. TR-72wb uploads data to the cloud service via the Internet. Users can browse historical data online and view the data via the apps of the two major mobile phone systems. This model is discontinued and replaced by TR-72A or TR-72A-S. Regarding the TR-72wf you asked about, it has been discontinued for a long time. The current model is TR-72A2. In terms of wireless network, the difference between the two is only in the supported wifi specifications.
