AQUATRAC ®-3EMoisture Meter for Plastics

The water content is in the processing of high-grade engineering plastics is an important parameter for the quality of the manufactured product.The required measurement should be quick and easy to perform.

The AQUATRAC ® - 3E is the result of continuous development of the familiar for 20 years Aquatracs.When measuring the moisture content of granular solids, it was developed primarily for the plastics processing industry.It is built to last and compact and can be easily transported by its new mobility.Therefore, there are many opportunities for direct use at the production site, for example when:

• Incoming inspection
• Monitoring and optimizing the resin drying
• measurement of the granulate to the machine
• measurement of the finished part, for exampleafter conditioning
• Laboratory measurements
As it does not require absolute meter calibrations for different substances.The use is independent of a PC or other peripheral possible.

Ranges

Different ranges are the AQUATRAC ® - 3E achieved by different weights.Slightest trace of moisture (less than 0.01% H2O) is measured at high, representative sample volumes (up to 100g).With reduced sample weight, the measuring range can be extended to very high humidities.Changing the measuring cup is no longer necessary, since with only one measuring cup accurate results.

Measurement procedure

The measuring volume consists mainly of the measuring cup, which contains the sample and reagent.The sample is weighed, the prescribed weight does not have to be exact.The read off on the scale weight is entered.The sample is then filled into the measuring cup.This is evacuated in a sealed reaction vessel automatically through the built-in pump, which requires about 30s.The vacuum is achieved <10 mbar absolute.The reaction vessel containing the sample is heated then it is given to temperatures of 60 ° C to 200 ° C, freely selectable.The few necessary operations are the AQUATRAC ® - 3E executed via a touchscreen.Optionally, the user can also be performed with a step by step guide through the measurement.


Principle

Water and calcium react with evolution of hydrogen according to the following equation: CaH2 + 2 H2O Ca (OH) 2 + 2 H 2 This reaction is the AQUATRAC ® - 3E in a closed vessel, the reaction vessel from.It will be evacuated prior to the measurement with a built-in vacuum pump, and during the measurement, electrically heated.By heating the released water vapor reacts with the calcium hydride and the pressure in the measurement system increases by the developing hydrogen.The gas pressure is the amount of water brought in strict proportion, because the reaction is specific for water.The gas pressure is a measure of this method.The ratio of pressure and sample weight is calculated and the result is displayed in% or ppm H2O water content.Other volatile substances are condensed in a cold trap and thus take no part in the measurement.The reagent is heated above the material sample.The partial pressure of water vapor in the reaction vessel is zero, therefore, the water content is defined completely.Together with the effect of vacuum and temperature results in a faster reaction.Also by the vacuum is the measurement process without the presence of oxygen may be disturbing.

Reagent

The reagent calcium hydride is used in granular form.It is non-toxic and environmentally friendly, so no special disposal is required.Using a measuring spoon, the reagent in the AQUATRAC ® is - 3E filled.This charge is used several times, with the resulting amount of hydrogen is very low at each measurement.The reagent is available in pack sizes of 250 g, which is sufficient for approximately 1000 measurements.

Product Database

In AQUATRAC ® - 3E already extensive product database with the information necessary for the density and temperature measurement is stored.Thus, measurements can be performed quickly, without having to enter additional parameters.This database can be added or edited at any time, and thus adapted to customer needs.
