Servomex – Monitoring of Moisture Contaminant

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.

• 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
