Description
The Model 3050 Moisture Analyzer series measures trace levels of moisture in a gas through the use of a quartz-crystal oscillator sample cell. AMETEK is the leader in quartz-crystal technology, which for thirty years has offered significant advantages over other measurement techniques:
- It is the most accurate trace moisture measurement technology available.
- It responds far faster to both increasing and decreasing moisture levels.
- It is specific to moisture in most applications.
- It provides a much more rugged sensor.
Because of these advantages, the quartz-crystal oscillator has become the industry standard for applications ranging from ultrahigh purity semiconductor gases to natural gas streams containing 30% H2S. Now, the Model 3050 analyzers bring the benefits of quartz-crystal technology to a broad spectrum of moisture applications.
