Dual Channel Negative Pressure Seal Tester for Packaging Bags

Introduce
The intelligent tightness tester is a new type of high-precision non-destructive testing equipment. It mainly uses compressed air as the medium, exerts a certain pressure on the inner cavity or surface of the product to be tested, and then uses a high-sensitivity sensor to detect the change of pressure to determine the tightness of the product to be tested. Because it uses compressed air as the medium, there is no secondary pollution to the product, and the detection speed and accuracy are also better than water detection (air molecules are smaller than water molecules, and the leakage speed is fast), so it can be implemented on a large scale in the production line. The instrument's convenient operation interface and economical and practical cost performance have won high praise in the market. The functions and performance parameters of the instrument can meet the needs of most customers.

Features
1. High precision: The imported pressure sensor combined with the company's independent research and development of high-precision computing and calculation modules has high detection accuracy, comparable to the accuracy of the differential pressure sensor, and has a larger detection range than the differential pressure sensor.
2. AI algorithm/human-computer interaction: collect the information of the test products, obtain the effective data chain of the samples through big data analysis, and automatically determine the test data against the database intelligently; through a large number of user feedback information and practical analysis, the instrument operation process and The interface is convenient and simple, progressive setting, extremely simplified operation; operation authority password protection, user-friendly design such as grading of inspection and query modification authority.
3. High stability/high efficiency: self-developed air circuit control components improve ventilation efficiency, tightness and stability. In the inflation/balance/pressure-holding stage, large leakage and micro-leakage states are screened respectively, and the large leakage state is determined in the inflation stage. Leakage, micro-leakage is determined in the pressure-holding stage, and it is determined and displayed separately, which greatly saves the detection time.
4. Non-standard customization: It has strong independent research and development capabilities, and has developed a variety of special-purpose air tightness comprehensive functional testing equipment according to customer needs, providing one-stop solutions.
