XMT9007-8 temperature & humidity control instrumentⅠ. General introductionThe 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,Website: , 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.II. Main Technical Specifications1.Accuracy: Temperature measurement accuracy +0.5%F.S+1.0character                   Humidity measurement accuracy + 2.0%F.S+1.0 character2.Temperature measurement range:-50.0-150.0℃3.Output relay: AC220V 5A4.Power-off data-retention time: over 10 years 5.Work Power: AC85～242V  50/60Hz     Power consumption less than 5W6.Normal working ambience: Temperature: 0-50℃ ,Relative humidity: 35%-85% without corrosive gas-free space7.Power on, in case"-----"or "----", or "100% humidity" is always displayed in both the upper and lower row windows respectively, please, check if the wire of the sensor is broken, or if a case of short circuit or other problem, such as wrong connection, etc. Ⅲ.
