Details
The AL-700 Series Differential Pressure Air Leak Tester integrates a high-sensitivity differential pressure sensor for superior testing precision, and is fitted with a large-bore pneumatic control valve. Boasting an intelligent testing function, the tester is engineered with a correction feature tailored to the operational characteristics of differential pressure leak testers. This feature effectively eliminates errors induced by temperature fluctuations and structural deformation, enabling high-precision measurement in a short time and thus significantly enhancing overall testing efficiency.
