DF-740

The DF-740 is designed specifically to monitor trace levels of moisture in electronics-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 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.

This device 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. The combination of high performance, ultra-stable measurements and affordability make the DF-740 an attractive solution for electrograde NH3 quality checking applications.

Features:
  • Trace level Tunable Diode Laser (TDL) sensing provides high stability measurements through minimal moisture contact with optical elements
  • Broad detection range: 1ppb – 10ppm
  • Operable via front panel or digital communication options
  • Simplified ongoing maintenance requirements with no consumables required
  • High reliability; repeatable baseline measurements are not affected by a loss in mirror reflectivity
  • Designed for long term unattended operation with minimal maintenance needs
