EASY TO USE
DF-740 NanoTrace
The DF-740 is designed specifically tomonitor trace levels of moisture inelectronics-grade ammonia. Servomex’s
industry-leading TDL sensing technology
and robust Herriot Cell enables an
exceptionally broad measurement range of
10ppb-10ppm. By ensuring moisture only
comes into contact with minimal opticalcomponents, the DF-740’s performance isunaffected by loss in mirror reflectivity ensuring a fast response measurementthat is stable, accurate and consistent.
This device is designed for long term
unattended operation, delivering
considerable cost-savings. The highstability optical TDL technology requires
minimal ongoing maintenance, with zerodrift enabling greatly extended calibrationintervals. The combination of highperformance, ultra-stable measurements
and affordability make the DF-740 an
attractive solution for electrograde NH3
quality checking applications.

High stability TDL measurements

ALTERNATIVE PRODUCTS

When you need a solution that can undertake quality checks ofelectrograde NH3 during bulk gas checks for LED manufacture, youneed 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 canreduce your ongoing costs and provide operational efficiencies.
We don’t believe you should have to compromise.

The DF product range features anumber of options designed to meetyour application needs.

DF-730
NanoTrace
Designed to analyze moisture contaminationin electronics grade HCl, the DF-730’s highly
sensitive performance is ideal for quality
control and leak detection applications.

A no compromise solution
The DF-740 has been designed to deliver optimum performance in themeasurement of trace moisture in ammonia. This device uses leadingedge 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 ameasurement 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 andmeasurement data.

DF-745
NanoTrace
Designed to measure moisture as acontaminant in UHP quality gases, the DF-750’s
trace/ultra-trace measurement is optimized forbulk gas control in 300m semiconductor fabs.

Simple maintenance and reduced
ongoing costs
The DF-740 is also optimized to provide significant cost savings over along product lifetime. The use of a high stability, zero drift TDL sensor
extends calibration intervals and minimizes ongoing maintenance. Insummary, 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.

DF-760E
NanoTrace
The DF-760E combines TDL and Coulometricsensing to create a unique integrated
ultra-trace measurement for moisture andoxygen - ideal for PCB bulk gas quality checks
and leak detection.
