Leak Tester Model 628 Differential Pressure Decay
The Uson 628 Differential Pressure Decay Leak Tester is designed to check the integrity of parts and products by measuring changes in pressure. It supports Differential Pressure Decay, Differential Vacuum Decay, and Vacuum Decay test methods, making it suitable for applications that require accurate and clear Pass/Reject results.
The 628 is available with five Test Pressure ranges, allowing it to cover a wide range of applications, from Medical Check Valves to Automotive Radiators, as well as applications in the Medical and Packaging industries. It uses a Capacitive Differential Sensor for Leak Rate Measurement, with a Resolution of 0.01 mbar / 1 Pa / 0.0001 psi. The system also uses 24-bit high-resolution measurement to provide precise pressure measurements.
