The SLD-100 Smart Leak Detecter provides a new leal test method that can run without expensive helium gas. Thanks to our unique gas analyzer used as the leak sensor, you can use inexpensive gases such as argon or even air as the test gas instead of helium, and at the same time you can perform high-sensitivity leak test. The SLD-100 Leak Detector is applicable to many industrial leak test applications (where helium leak detectors are currently used), such as automobile parts, refrigeration and air conditioning components, heat exchangers, gas components, pumps and compressors, medical parts, food packagings and much more. SLD-100 is also can be substituted for air leak detectors and bubble leak testers as well.
