Xentaur XTDL-HT

Optical Moisture Meter for Heat Treating Applications and Moisture in CO2 Applications. The XTDL-HT™ is designed with a new proprietary optical sampling system for the dirty blanket gases in your Heat Treating applications that causes other analyzers to be damaged, readings to drift and a measurement that cannot be trusted as reported by our many customers after 30 years in this business.


Tunable Diode Laser Spectroscopy

The Xentaur Moisture Analyzer Model XTDL-HT™ is designed with a new proprietary optical algorithm based on GasScan™ TDLAS technology from Physical Sciences Inc. All optical and sample system components are designed to handle the high particulate levels found in harsh blanket gas environments.

TDLAS technology results in fast, accurate and reliable moisture measurement of blanket gases improving the ability to control the finish of the parts in a variety of heat treating processes. The XTDL-HT™ is low maintenance and can be cleaned if necessary in the field without effecting the optical alignment.
