Intelligent RS485 Communication Temperature And Humidity Controller
XMT9007-8 temperature & humidity control instrument
Ⅰ. General introduction
The XMT9007-8 temperature & humidity instrument is an intelligence instrument based on the computer technique. It adopts a 2-row digital 8 high-light 7 sect LED and synchronous display both the humidity and drying temperature measured. The control parameters can be set by panel and displayed in real-time. The user can choose below functions：
1、Sensor: PT100 sensor for temperature measurement, PT100 OR high molecular sensor for the humidity measurement.
2、Control mode: PID and on/off mode for heat and humidity control. On/off mode for cool control. On/off control is convenient for using; PID control can improve the meter control precision.
3、Serial communication: the computer can make a long-distance control to the meter by RS485 serial module.
4、Print function: the meter can regularly print annals and sample value of temperature and humidity by connecting mini printer.
