AquaLab Dew Point Moisture Analyzer 4TE Duo
How It Works
Most moisture analyzers use chemicals or high temperatures. Not AquaLab. Instead, an infrared beam focused on a tiny mirror determines the precise water activity of the sample. That water activity reading is then translated into moisture content, based on a product-specific calibration model.
What Products Work?
Most products with less than 40% moisture (by weight) will work using the dew point method. Products with moistures above 40% usually have such uniformly high water activity values that other moisture analyzers are a better fit. Below 40%, moisture changes affect water activity readings more strongly, yielding high precision and repeatability.
Easy to Use
The instrument is lightweight, portable, and straightforward. A worker at the line can run samples with the same precision as a technician in the lab, so you can use your moisture analyzer at any point on the production line or in the supply chain.
10x the Precision
Precisions varies with the product you're testing, but for many products dewpoint moisture analyzer has 10 x the precision of a typical moisture meter.
Independently Verifiable Readings
You can validate moisture analyzer performance with independently verifiable salt standards. Time, date, and user stamped calibration and sample data can also be stored onboard in password protected data files.
Half the Cost
The dewpoint method's precision puts it in the same class with high-end moisture methods, but because its sample cups are inexpensive and reusable, DUO costs less to run than other moisture analyzers.

Accessories
Printer
Print data straight from AquaLab in real time.
The printer has a 4.5 x 5 inch footprint (it's just over 2 inches tall), prints up to 40 characters per line, and uses 2.25 adding machine paper.
Temperature Equilibration Plate
Reduce reading time by pre-equlibrating the sample to instrument temperature on the temperature equilibration plate. The equilibration plate holds samples at any preset temperature between -10 and 100 º C.
Travel Case
Protect your AquaLab during transport. Airtight/watertight seal with extra thick wall construction. The series specific foam cutouts allow for a perfect fit. Specify series and model numbers when ordering.
Verification Standards
Use to check your instrument daily. Standards are salt solutions with specific molality and water activity (See your operator's manual for available molalities and water activities.)
