Unrivalled performance
Benchmark compliance

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.
