Delta F moisture analyzers use Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology to measure moisture in gases. TDLAS is a spectroscopic technique that uses a diode laser as its light source. TDLAS has advantages over other techniques because the moisture sample only comes in contact with a few optical components that are made from very
robust materials. It works according to the fundamental principle of Beer's law; therefore the reading is stable over time and does not ever require calibration.

Using Lasers for Unmatched Accuracy and Reliability
Drift Free Operation - Combination of self-correcting optics and the laser line locking onto the water peak removes all possibility of significant drift.
High Accuracy/ Low Maintenance - Based on Beer's Law, the measurement requires no field span calibration.
Unparalleled Performance - Spectroscopy allows sub-ppb level readings instantly! Other measurement techniques with solid surfaces require lengthy adsorption and desorption times.
Increased Capabilities - When packaged with the NanoTrace II Oxygen Analyzer, you can easily make both oxygen and moisture measurements from a single unit.
