Product Introduction
Adopts imported temperature measurement unit, with high measurement accuracy and strong anti-interference ability.
The 485 communication interface uses the standard ModBus-RTU communication protocol. The address and baud rate can be set, and the maximum communication distance is 2000m.
The on-site power supply adopts 7~30V DC wide-voltage power supply, which can adapt to various DC power sources on site.
The product adopts G1/2 thread installation, which is convenient for installation. Its protection rating is IP65, making it suitable for harsh outdoor on-site environments.
