XMT9007-8-4 temperature and humidity meter is an intelligent instrument with dual digital tube display for humidity and dry temperature, optional sensors, PID and bit control modes, serial communication, printing function, etc.
The XMT 9007-8-4 is an intelligent temperature‑humidity instrument that displays humidity and dry‑temperature simultaneously on dual 7‑segment displays. It supports high‑polymer or dual PT100 sensors, offers PID or positional control for heating, humidifying, dehumidifying and cooling, and can communicate via an RS485 serial module for remote computer control.
The manual describes the panel layout, how to enter the parameter setting menu, detailed internal parameters, control logic, model designation codes, terminal wiring, safety precautions, and a specific method for using dual PT100 sensors to measure humidity. This manual is written in Chinese.
