PRODUCT DESCRIPTION

Product Introduction
The product is a wall-mounted high-grade enclosure with a protection grade of IP65, rain and snow proof and good air permeability. The circuit uses imported industrialgrade microprocessor chips, high-precision temperature sensors, and environmental monitoring sensors. Ensure product reliability. This product adopts a particle sintered probe sheath, and the probe is directly connected to the shell and has a beautiful appearance. The output signal type is divided into RS485, which can realize longdistance transmission. The standard modbus protocol supports secondary development.
