This Computrac SMA-500 is revolutionary moisture analyzer for the plastics industry. Developed as an alternative to the Karl Fischer titration system with a drying oven.

Principles of Operation:

The SMA-500 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 20mL septum bottle. Evolved volatiles are passed through a cold trap filter to a 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 part-per-million or % moisture. Phoemis 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.

Accurate Results:

The heating range of the SMA-500 is 25℃to 275℃and is accurate within 1℃. Depending upon the sample and test temperature and test ending criteria can be altered to optimize speed and accuracy. Designed for either lab or production floor use, the SMA-500 Moisture Analyzer brings to the forefront state-of-art-technology specifically designed to provide accuracy and precision in a timely manner, so that over-drying is eliminated and product quality is maintained.
