Constant temperature and humidity test chamber 2970L large capacity programmable

1、 Product Usage:

Suitable for electrical, electronic, instrumentation, automotive electrical, electronic component materials and other products, with adaptability for storage and use under high and low temperature environmental conditions. Suitable for schools, factories, military industries, scientific research, and other units to test the performance indicators of various electronic components in high temperature, high humidity, low temperature, and alternating high and low temperature humid environments.

twoTechnical parameters:

threeBox structure

1. The box has a beautiful and elegant shape, processed by CNC machine tools, and adopts non reactive handles for easy operation.

2. The inner liner of the box is made of imported high-grade stainless steel（SUS304 mirror panel/brushed plate (overall sheet metal structure), the box body is made of cold-rolled steel plate electrostatic spraying, which increases the appearance texture and cleanliness.

3. The large observation window is equipped with lighting to keep the inside of the box bright, and uses tempered glass embedded in the heating body to observe the condition inside the box clearly at any time.

4. The left side of the box is equipped with a diameter50mm test hole, suitable for external testing power or signal lines. (The aperture or number of holes must be specified when placing the order).

5. The bottom of the machine adopts high-quality fixable designPU activity wheel.

4、 Control system:

1．The temperature control instrument adoptsIndustrial gradePLC“SH1800”7 incheslarge screenColor TouchScreen operation is simple, program editing is easy, and there is no need for key input. The operation buttons can be directly touched and selected. The controller operation interface is available in both Chinese and English for selection.

2．have99 sets of programs100paragraphThe capacity of the 99 loop steps is set to a maximum of 99 hours and 59 minutes per time interval.

3．After inputting the data and experimental conditions, the controller has a screen lock function to avoid manual touch and shutdown.

4．standard configurationUSB export data interface.

5．Has upgradable featuresRS-232 or RS-485 communication interface, which can be programmed on a computer to monitor the testing process and perform functions such as automatic power on/off (optional).

6．Equipped with automatic calculation function, it can immediately correct the temperature and humidity change conditions, making temperature and humidity control more accurate and stable.

7．The main control system comes with a built-in data storage function, which allows users to directly query historical data on the operation interfaceThe function of copying, exporting, or modifying parameters.Provide on-site installation confirmation, operation confirmation, and performance confirmation.

8．equipmentcompile, edit, weave, organizeThe curve interface, Has strong maneuverability and is convenient for viewing and modifying curves, allowing for clear visibility Pre preparedRun the program to facilitate program inspection, improve experimental efficiency, and avoid errors.

5、 Refrigeration and dehumidification system:

1. The refrigeration unit is separated from the casing and the refrigerant is transported through pipelines

2. The refrigeration unit is made of original French equipmentTaikangorEmersonfully enclosedlow temperaturecompressor.

3. The refrigeration system adopts a binary low-temperature circuit system design.

4. Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, can make the temperature and humidity distribution in the testing area uniform.

5. The design of wind path circulation for air outlet and return ensures that the wind pressure and speed meet the testing standards, and can quickly stabilize the temperature at the moment of opening the door.

6. Heating, cooling, and independence can improve efficiency, reduce testing costs, increase lifespan, and decrease failure rates.

7. The original condensing dehumidification unit adopts surface cooling condensation method. When the indoor saturated steam is higher than the set value, the dehumidifier automatically starts active condensation to reduce air humidity. The dehumidifier runs automatically during low humidity operation for a long time.

6、 Compliant with standards:

Product meetsRequirements of national standards such as GB 2423.1-2001, GB 2423.2-2001, and other relevant standards. Strictly design and manufacture according to the technical conditions of GB 10592-89 high and low temperature test chambers, and can produce various high and low temperatures according to military standard test requirements GJB150.3-86, GJB150.4-86, and non-standard productiondamp-heatEnvironmental testing.
