Digital Static Tester

The Digital Static Tester (DST) measures the leakage rate of a seal (or other component) quickly and accurately, whether the seal is new or refurbished. It can be used to test the flow of any system’s seal regardless of seal type or size.

Consistent and repeatable results are obtained by precisely applying air pressure to a seal placed within the specially designed fixture. The DST provides data in real time and utilizes the actual temperature, actual absolute pressure, volumetric flow rate, and is calibrated to the specific gas being used. The system software yields the mass flow rate corrected to the customer selected standard units.

The easy-to-read digital display eliminates human interpretation and errors inherent in systems utilizing rotometers and analog pressure gauges. The RS-232 port allows the test data to be directly downloaded to a computer.

Using the DST in conjunction with a fixture specifically designed for the seal being tested is critical to the accuracy of the process. To ensure the integrity of the testing, Stein Seal Company will fabricate a fixture for your application regardless of whether you are testing a Stein Seal product or another manufacturer’s seal.
