Delta F (DF) has been manufacturing industry-standard ultra-high purity moisture analyzers for more than 15 years
The tunable diode laser (TDL) sensing technology has proven to be a reliable, robust sensing technology measuring ultra-trace levels of moisture in Semiconductor process gases
DF700 Series moisture analyzer are used in a multitude of applications including:
- Specialty gas blending
- Electronic gas production
- Semiconductor continuous quality control (CQC)
- LED manufacturing
■Over a year of testing and development have produced firmware improvements to greatly improve low-end stability in ultra-trace measurements
■New Baseline Optimization
–NBO allows for ultra-stable baseline measurments
–Insignificant long-term drift
–Intelligent transient spike rejection
–Improved O2 sensor temperature stability
–Allows for high-level of confidence in meeting low-end stability
■DF500 & DF700 Series analyzers being re-introduced for 2015
–Enhancements include
•New white enclosure with purple key pad
•Key pad icons changed to standard Servomex analyzer icons
•New Baseline Optimization (NBO) firmware loaded on all new analyzers
•Lower detection limits
•Improved user interface
•Longer internal data-logging in DF700 Series
•CO2 as a background as for DF700 Series including; DF745 ,745SGMAX, 749 and 750
■DF700 Series user interface update
–All DF700 analyzers, except DF760, will now display the real-time moisture reference spectrum
–The reference spectrum shows that the laser is locked on the correct moisture peaks and is analyzing the correct part of the IR spectrum
–This reference spectrum give confidence to the user that the analyzer is functioning properly and is giving good data
–If the real-time reference spectrum does not look like the picture shown then the analyzer is not giving good data…
Green “OK” means there are no internal system faults. If there are any faults with the analyzer it will turn Red and display a different message
