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. 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; Product intelligence * Fusion of measurement technology and Internet of things technology to wifi remote control to make measurement easier * HD touch screen control, multi-touch, greatly improve user experience, * One-click start, automatic control, shorten the training period for metering personnel * Timing switch machine, remote switch machine, save time, improve verification efficiency Excellent quality * The shell adopts thick plate phosphating, passivation, spray molding, anticorrosion, rust prevention, salt spray resistance; * SUS304 for internal bile * High precision sensor, temperature and humidity control with imported high precision * With intelligent image acquisition system, dew point meter and industrial control computer, it can be upgraded to intelligent temperature and humidity meter automatic verification system to realize the automation of verification process, the automatic preservation of records and the automatic generation of reports.
