TUNABLE DIODE LASER (TDL) SENSOR TRACE/ULTRA-TRACE MOISTURE MEASUREMENTS FOR CHECKS OF ULTRA HIGH PURITY ELECTRONIC GASES FLEXIBLE 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 EASY TO USE ■ Highly reliable with repeatable ■ Compact with a low weight; baseline measurements unaffected moves easily from port to port and by loss of mirror reflectivity    ideal for other mobile applications LOW COST OF OWNERSHIP ■ Robust sensor construction    ■ Zero drift measurement reduces maintenance requirements extends calibration intervals DF-749 NanoTrace 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. Unrivalled PERFORmaNCE Offering an ultra-sensitive Lower Detection Limit (LDL) of 250ppt, this device uses industry-leading Tunable Diode Laser (TDL) sensing technology, delivering ultra-reliable baseline measurements and a fast speed of response. This analyzer is also highly affordable over product life, with a robust sensor construction that has low lifetime maintenance requirements and a zero-drift measurement stability that greatly extends calibration intervals. Factory pre-calibration also provides simplified set up. ■ Manufactured by Servomex -over 60 years' experience with thousands of units used in the field ■ Analysis immune from gas cell concentration: DF-749 operates to specification with up to 90% signal loss ■ 250ppt Lower Detection Limit (LDL) ■ Overvoltage Category II,    ■ EU Low Voltage Directive Learn more about the DF-749 NanoTrace VISIT SERVOMEX.COM
