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.

|Range||Calibrated from 0.1 to 2500 ppmv. Readout capability in ppmw, lb/mmscf, mg/Nm3 and dew point in ºC or ºF (requires process pressure as an input)|
|Reference Gas||Continuously produced using actual sample gas|
|Online Verification||Internal moisture source with NIST-traceable calibration enables on-demand verification of analyzer accuracy and responsiveness without uninstalling the analyzer|
|Accuracy||±10% of reading from 1 to 2500 ppmv with standard calibration; special calibration ranges not required|
|Reproducibility||±5.0% of reading from 1 to 2500 ppmv|
|Limits of Detection||0.1 ppmv|
|A/D Resolution||16-bit (0.0015%)|
|QCM Response Time||Near real time. Computer-enhanced response, which may lead to errors is not required to obtain quick wet-up or dry-down response|
