Intelligent PID Temperature And Humidity Controller

XMT*9007 temperature & humidity control meter                

?. General introduction

The XMT*9007 temperature & humidity meter is a new intelligent meter based on the computer technique. It adopts a 2-row digital tube system to make a synchronous display of both the humidity measured value and the temperature measured value. Every datum concerned used for control purpose can be keyed in from the top panel which is accompanied by an actual time display. The temperature measurement sensor selects PT100, the humidity measurement selects high molecular sensor. This meter  has  a free setting temperature value for heating time proportional control or ON/OFF control (the temperature upper limit), and for cool  ON/OFF control (the temperature lower limit); in addition, this meter also has a ON/OFF control system by a free setting of  the upper and lower limits of the humidity. The meter is a high accuracy and high integrity meter for measuring temperature and humidity.
