Computrac 3000 Moisture Analyzer

The Computrac 3000 is a revolutionary moisture analyzer for the plastics industry. Developed as an alternative to the Karl Fischer method, the Computrac 3000 does not utilize reagents, is simple-to-operate, minimizes consumables and correlates with the precision and accuracy of the Karl Fischer titration system with a drying oven.

Principles of Operation: The Computrac 3000 consists of a cylindrical sample bottle heater, a dry carrier gas flow system and a moisture transducer. The instrument heats a sample of test material contained in a 20 mL septum bottle. Evolved volatiles are passed through a cold trap filter to an analysis cell, where the moisture content of the flowing gas is measured. A microprocessor integrates the varying moisture signal and converts the integrated signal to micrograms of water for display. If the sample weight has been entered, the moisture concentration in the sample is calculated as parts-per-million or % moisture. Arizona Instrument's revolutionary prediction algorithm automatically terminates the test when sufficient information is collected to allow accurate determination of the moisture content of the sample.
