Temperature and humidity vibration three comprehensive testing machine

Temperature and humidity vibration three comprehensive testing machine

The temperature and humidity vibration three comprehensive testing machine is widely used in national defense, aviation, aerospace, communication, electronics, automobiles, home appliances, original equipment and other industries. Vibration is for storage, transportation, actual situation assessment and structural strength test in the environment. The equipment has a wide range of applications, and the test effect is remarkable and reliable. Sine wave, sine, programmable, frequency multiplier, logarithm, maximum acceleration, amplitude modulation, time control, full-function computer control, simple constant acceleration/constant amplitude. The equipment has passed the 3-month test of Lianjing trouble-free operation, with stable performance and reliable quality.



1. To ensure strength, the test chamber is welded with an overall frame to ensure that the box does not deform.

2. Vibrating tables of different specifications and models are optional, and different seals are equipped according to the connecting joints and linking methods of the vibrating table.

3. Ensure that the test chamber and the vibration table are completely sealed during the three-integrated operation, and the vibration table has good mechanical transmission characteristics;

4. The bottom of the test chamber is equipped with a slide rail that can be separated from the vibration table. When testing is required, the vibration table and test chamber can be tested separately.

5. Has a wide temperature and humidity control range

6. The balanced temperature and humidity adjustment method is adopted to achieve a high-precision and stable temperature and humidity controller.

7. It adopts imported original high-precision programmable temperature and humidity controller, 7-inch true color touch screen operation, equipped with Ethernet interface of more than 10m/100m, and comes with free operating software.

8. Imported refrigeration compressors are used, and the refrigeration adopts a new cold-end output control. Compared with the traditional hot and cold balance, it greatly saves energy consumption and reduces customer usage costs;
