DF-745 NanoTrace
Tunable DIODE LASER (TDL) TRACE/ULTRA-TRACE MOISTURE MEASUREMENTS FOR ULTRA HIGHPURITY ELECTRONIC GAS CHECKSFlexibleT race level Tunable Diode Laser(TDL) sensing provides highstability measurements

Operable via front panel or digitalcommunication options

Broad detection range:
0ppb – 20ppm

EASY TO USE
DF-745 NanoTrace
The DF-745 provides trace and ultra-tracemoisture contaminant measurements for
LED/LCD manufacturing processes. Able tomonitor multiple background gases, theDF-745 delivers exceptional performanceoperational flexibility in a compact unit.
With an intelligent and robust hardware/
software design, this analyzer can be
moved easily from port to port, virtuallyeliminating dry down times often
associated with these applications.
Offering a Lower Detection Limit (LDL)of 1ppb, the DF-745 uses industry-leading
Tunable Diode Laser (TDL) sensing
technology. This sensor delivers ultrareliable baseline measurements and a fast
speed of response; with a robust Herriot
cell preventing loss in mirror reflectivity,
moisture contact with optical components
is minimized, ensuring an accurate
measurement. Added to its flexibility
and accuracy is affordability; zero drift
extends calibration intervals while minimal
ongoing maintenance provides a low costof lifetime ownership.

Flexible TDL trace andultra-trace measurements

ALTERNATIVE PRODUCTS

Modern LCD and LED manufacturing processes require anultra-trace quality measurement for moisture contaminants in highpurity electronics grade gases. In such a specific application, users
need analysis capable of delivering high-accuracy and ultra-low
detection limits in multiple background gases. No matter how specificthe application requirement, you’ll want a device that actively reducesongoing costs to deliver a long and cost-effective lifetime of ownership.
We don’t believe you should have to compromise.

A no compromise solution
Utilizing advanced Servomex Tunable Diode Laser (TDL) sensing
technology, housed in a robust Herriot cell, the DF-745 delivers afast, accurate trace moisture measurement with a low detection limitof 1ppb. The measurement stability of TDL means the DF-745 exhibits
zero drift and recovers fast from upset prone applications. Application
flexibility is optimized through a compact size that keeps port to port
mobility simple.

Simple maintenance and reduced
ongoing costs
Proven sensing technology and advanced functionality delivers DF-745
users a low lifetime cost-of-ownership. Factory pre-calibration helps
facilitate quick and easy installation; the use of the high stability, TDL
sensor - with zero drift potential - extends calibration intervals andminimizes ongoing maintenance needs, enabling considerable savings
over a long product lifetime.

The DF product range features anumber of options designed to meetyour application needs.
