A trace moisture analyzer using Tunable Diode Laser (TDL) sensing technology, the DF-740 is designed to measure contaminants in UHP-grade ammonia.
The DF-740 is designed specifically to monitor trace levels of moisture in electronics-grade ammonia (NH3) used in LED plants. Industry-leading TDL sensing technology and a robust Herriott Cell enable an exceptionally broad measurement range of 10ppb-10ppm.
By ensuring moisture only comes into contact with minimal optical components, the DF-740’s performance is unaffected by loss in mirror reflectivity – ensuring a fast response measurement that is stable, accurate and consistent.
The DF-740 is designed for long-term unattended operation, delivering considerable cost-savings. The high-stability optical TDL technology requires minimal ongoing maintenance, with zero drift enabling greatly extended calibration intervals.
When you need a solution that can undertake quality checks of electrograde NH3 during bulk gas checks for LED manufacture, you need a device that delivers high measurement accuracy, excellent stability – and is capable of being left unattended for extended periods. A robust design that removes issues associated with mirror reflectivity loss is a must and so is the need for a broad monitoring range. No matter your specific application needs, you’ll want a moisture analyzer that can reduce your ongoing costs and provide operational efficiencies. We don’t believe you should have to compromise.
The DF-740 has been designed to deliver optimum performance in the measurement of trace moisture in ammonia. This device uses leading-edge TDL sensing technology housed in a sturdy Herriot Cell, ensuring there is no loss of mirror reflectivity, thanks to minimized moisture contact with any optical components. This ensures the DF-740 gives a measurement that is highly stable, reliable and capable for being left unattended for long periods – a benefit supported by comprehensive data logging which captures and recalls calibration, system error and measurement data.
The DF-740 is also optimized to provide significant cost savings over a long product lifetime. The use of a high stability, zero drift TDL sensor extends calibration intervals and minimizes ongoing maintenance. In summary, the DF-740 is the ideal solution for your gas monitoring needs, thanks to the combination of its ultra-high performance capability, stable reliability and operational efficiency potential.
