THM-100 Wireless Temperature & Humidity Monitor

THM-100 wireless temperature and humidity detection system is composed by wireless temperature detection probes, humidity detection probes and display terminals. Adopting the advanced wireless temperature detection technology, THM-100 transmits and displays the real time value detected from the local detection probes for the purpose of inspecting temperature and humidity on-site routinely.


  • Complete user management function
  • Add, sort, and setup property of the temperature detection probes on line
  • Aggregated operating time management function
  • Wireless communication disconnection detection and alarm function
  • Exceed limit alarm function
  • Trend wave local display function
  • History data record and search function
  • Self-diagnosis function and fault signal auto sent when diagnosized
