DF-740 NanoTrace Tunable Diode Laser Trace Moisture Analyzer

Brand: SERVOMEX

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 10 ppb to 10 ppm.

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.
