Servomex DF-749 NANOTRACE



Servomex – Monitoring of Moisture Contaminant

The DF-749 provides trace and ultra-trace moisture contaminant measurements in various background gases including nitrogen, hydrogen, helium, argon and oxygen. Ideal for quality checking of UHP gases used in LCD and LED manufacture, the DF-749’s compact form makes it easily portable for easy cart or mobile use. A robust hardware/software design virtually eliminates dry down times often associated with UHP gas checking.

  • Trace level Tunable Diode Laser (TDL) sensing provides high stability measurements through minimal moisture contact with optical elements
  • Broad detection range: 0-20ppm
  • Flexible configuration options: initiation via front panel/digital interconnect
