DTSL Series Temperature and Humidity Verification Chamber is used to test some dedicated devices like hair temperature and humidity indicator(meter),dry and wet blub temperature and humidity meter,digital temperature and humidity meter,temperature and humidity transmitter and so on.The device is accurately measured by the temperature and humidity sensor and controlled by the industrial programmable controller,which can realize the automatic adjustment of the humidity in the temperature and humidity check box.With high control and test accuracy,it provides continuous,reproducible humidity measurement for scientific research and product testing.All technical indexes and functions of the device accord with the requirements from”JJG205-2005 Examination Regulation of Mechanical Temperature and Humidity Meter”and”JJF1564-20 16 Correction Regulation of Temperature and Humidity Standard Box”.

Features:

Excellent technology

n Humidity control adopts the principle of shunting humidity generation,which greatly shortens the time required for stabilization and provides verification efficiency compared to the principle of dual-temperature humidity generation.

n The temperature control adopts the liquid bath constant temperature and other plate heating technology,the liquid medium heat radiation,the temperature is more constant,and the temperature field is more uniform.。

n The unique air circulation design inside the measuring chamber ensures the air flow without dead angle;the frequency conversion technology is adopted to adjust the speed of the fan to ensure that the internal temperature field is even at low speed;

Product intelligence：

n Integrate metering technology with IoT technology,wifi remote control,making metering easier

n High-definition touch screen control,multi-touch,greatly enhance the user experience,

n One-button start,fully automatic control,shorten the training period for metering personnel

n Time switch machine,remote switch machine,save time and improve verification efficiency

Excellent quality：

n The outer shell is made of thick plate phosphating,passivation,spray coating,anti-corrosion,anti-rust and salt spray resistance;

n The liner adopts SUS304

n High-precision sensor,imported high-precision platinum resistance,Rotronic humidity sensor for temperature and humidity control

Upgradeable to automatic verification system：

• With the intelligent image acquisition robot,dew point meter and industrial computer,it can be upgraded to the intelligent thermometer and hygrometer automatic verification system,realizing no automatic intervention in the verification process,
• automatic recording and automatic report generation.Free the metering personnel from the reading and recording of the temperature and humidity meter,greatly improving the verification efficiency and reducing the labor cost.
