I. General introduction The XMT 9007-8 temperature & humidity instrument is an intelligence instrument based on the computer technique. It adopts a 2-row LED display and synchronous display the humidity and drying temperature measured value. The user can choose below functions: 1.1 Sensor: PT100 sensor for temperature measurement, PT100 or high molecular sensor for the humidity measurement. 1.2 Control mode: PID or ON/OFF control mode for heating and humidification output, it is alternative. Cooling can set to delay output function. 1.3 Serial communication: The instrument can communicate with the computer to realize the computer on the instrument's remote control by installing the RS485 serial communication module. Using MODBUS RTU communication protocol. 1.4 Print function: The instrument installs printing module, it can regularly print the recorded temperature and humidity sampled values.
