Products Description DTLH low humidity intelligent temperature and humidity standard chamber is a special verification equipment for detecting hair temperature and humidity meter, dry and wet bulb thermometer, digital temperature and humidity meter and other kinds of temperature and humidity sensors. The equipment can automatically adjust the humidity in the temperature and humidity verification box by accurate measurement of temperature and humidity sensor and industrial programmable controller control. High control and testing accuracy, can provide continuous, repetitive humidity measurement, suitable for scientific research and product testing. Main features Advanced technical principles * Humidity control adopts the principle of moisture occurrence by shunt method, which greatly shortens the time required for stability and improves the verification efficiency compared with the principle of humidity occurrence by double temperature method. * Temperature control using liquid bath constant temperature plate heating technology, liquid medium heat radiation, temperature more constant, temperature field more uniform  * The unique air circulation design in the measuring chamber ensures no dead angle air flow, and adopts frequency conversion technology to speed the fan to ensure that the internal temperature field is uniform at low speed;
