Using Servomex’s Tunable Diode Laser (TDL) sensor the DF-749 provides trace/ultra-trace moisture measurements for checks of ultra-high-purity (UHP) electronic gases in a range of background gases.
The DF-749 provides trace and ultra-trace moisture contaminant measurements in a variety of background gases, including nitrogen, hydrogen, helium, argon and oxygen.
Ideal for quality checking of UHP gases used in LCD and LED manufacture, the DF-749’s compact form makes it easily portable for easy cart or mobile use. A robust hardware/software design virtually eliminates the dry-down times often associated with UHP gas checking.
Offering an ultra-sensitive Lower Detection Limit (LDL) of 1PPB, the DF-749 uses industry-leading TDL sensing technology to deliver ultra-reliable baseline measurements and a fast speed of response.
The analyzer is highly affordable over its product life, with a robust sensor construction that has low lifetime maintenance requirements and a zero-drift measurement stability that greatly extends calibration intervals. Factory pre-calibration also provides simplified set up.
Modern LCD and LED manufacturing processes require an ultra- trace quality measurement for moisture contaminants in high purity electronics grade gases. In such a specific application, users need analysis capable of delivering high-accuracy and ultra-low detection limits in multiple background gases. No matter what your application requirements, you need a moisture analyzer that can also provide operational cost efficiencies. We don’t believe you should have to compromise.
The DF-749 NanoTrace is ideal for your applications, combining high stability trace and ultra-trace measurements with flexible portability. Using state-of-the-art TDL sensing – with zero drift and a fast speed of response – this device provides high stability accuracy that is ideal for upset prone applications. With a low LDL of 1PPB and the ability to monitor multiple background gases in N2, H2, He, Ar and O2 gas streams with a single unit, the DF-749 NanoTrace delivers a high accuracy, adaptable monitoring solution: one enhanced by a compact design simplifying port-to-port mobility, making it ideal for either a fixed or cart-based solution.
Proven sensing technology and advanced functionality delivers DF-745 users a low lifetime cost-of-ownership. Factory pre-calibration helps facilitate quick and easy installation; data archiving makes the storage and recall of calibration, system error and measurement data simple. The use of the high stability, TDL sensor – with zero drift potential – extends calibration intervals and minimizes ongoing maintenance needs, enabling considerable savings over a long product lifetime.
