-10 High and low temperature humidity and heat test chamber Structural features :
one The box body is processed by CNC machine tool, which is beautiful and generous, and adopts non reaction handle, which is easy to operate.
two The inner box is made of imported stainless steel（ SUS304 ）Mirror panel, outer box adopts（ SUS304 ）Drawing stainless steel plate or cold-rolled steel plate is sprayed with plastic, which increases the appearance texture and cleanliness.
three It is equipped with large observation window and light to keep the box bright, and the use of heating body inlaid with toughened glass can clearly observe the condition of the box at any time.
four Diameter of left side of box 50mm The test hole can be used for external test power line or signal line.
five High density glass fiber cotton with thickness of 80~100mm 。 Double layer high tension sealing strip with high and low temperature resistance is used between the door and the box to ensure the sealing of the test area.
six It is equipped with independent temperature limit alarm system, exceeding the limit temperature and automatically interrupting the operation, so as to ensure no accident during the test.
-10 High and low temperature humidity and heat test chamber controller :
one Using a variety of imported controllers, users can choose according to their own requirements.
（ one ）Import TIME880 The color touch screen can program the temperature and humidity controller and switch interface between Chinese and English, which is easy to operate.
（ two ）Imported with original packaging TIME300 Digital display film button data input temperature and humidity controller, English display interface.
（ three ）Imported from Japan “OYO” Digital display touch button temperature and humidity controller, PID High precision control, put an end to long-term unstable operation.
two After the data and test conditions are input, the controller has locking function to avoid changing the temperature value by human touch.
three The controller of high and low temperature alternating test chamber has P.I.D With the function of automatic calculation, the temperature change condition can be corrected immediately to make the temperature control more accurate and stable.
four Optional printer can print and record the set parameters and scan the temperature change curve. 4~200mA Standard signal.
five The sensor adopts platinum resistance PT100Ω/MV 。
six have RS-232 The communication interface can design programs on the computer, monitor the test process and perform the functions of automatic switch on and off.
-10 High and low temperature humidity and heat test chamber Cooling system and heating system :
one Refrigeration system: totally enclosed French Taikang (or semi enclosed German grain wheel) compressor is selected. Air cooled single machine compression is adopted / Air cooled cascade compression refrigeration mode.
two Heating system: fully independent system, Ni Cr alloy electric heating heater.
three Air circulation system : The multi wing forced draft fan is used to supply air circularly to avoid any dead angle and make the temperature distribution uniform in the test area. The air pressure and wind speed meet the test standard, and the temperature can be stabilized quickly at the moment of opening the door.
four -10 High and low temperature humidity and heat test chamber Electrical control system: the main components of electrical control are imported “ Schneider ” and “ Meiri Meilan ” Element, better temperature control.
five Heating, cooling and system independence can improve efficiency, reduce test cost, increase service life and reduce failure rate. The output power of temperature control is calculated by microcomputer, so as to achieve high accuracy and efficiency.
-10 High and low temperature humidity and heat test chamber Electrical control system
The electrical control part adopts France "Schneider" AC contactor, thermal relay, reliable quality
Solid state relay is "Huajing" brand
Other components are well-known domestic brands "Delixi"
The design of electric circuit is novel and easy to operate
On the right side of the box is the electrical control cabinet, which is convenient for inspection and maintenance
