1.3What is a Moisture Analyzer?

The Ohaus Halogen Moisture Analyzer can be used to determine the moisture content of practically any substance. The instrument operates on the thermogravimetric principle: At the start of the measurement, the Moisture Analyzer determines the weight of the sample; the sample is then quickly heated by the integral halogen dryer unit and moisture vaporizes. During the drying operation, the instrument continuously determines the weight of the sample and displays the result. On completion of drying, result is displayed as % moisture content, % solids, weight or % regain.

6	MB45

1.3 What is a Moisture Analyzer? (cont.)

Of particular importance in practice is the rate of heating. In comparison with conventional infrared heating or the drying oven method, for example, the halogen dryer of your instrument needs a shorter time to reach its maximum heating power. It also allows the use of high temperatures; an additional factor in shortening the drying time. Response times for the control of production are shorter resulting in increased productivity.

All parameters of a measurement (drying temperature, drying time, etc.) can be pre-selected. The Moisture Analyzer offers many other possibilities. A few of these are listed here:

—The integrated database for drying procedures stores the settings for your samples.

—The drying characteristics can be matched to the type of sample.

—You can choose between various types of result displays at any time.

—Your settings and measurement results can be recorded and stored.

—Built-in battery backup stores valuable data during a power failure.

Even though the Moisture Analyzer contains many functions, operation remains simple. The three button controls on the front panel: Test Menu, Display and Setup allows entry into a variety of displays which includes a test library where previous samples are recorded along with the test parameters so that a similar sample can be run without the need to enter all new data. There are additional displays which indicate the test ID number, selected temperature, actual temperature, time, initial weight and moisture content in percent, solids in percent, grams or custom unit, % regain and a graphical display which illustrates the time and percentage.

Your Moisture Analyzer conforms with all common standards and directives. It supports standard procedures, work techniques and records as required by GLP (Good Laboratory Practices) and SOP (Standard Operating Procedure). We recommend the use of the OHAUS AS-142 Printer. Your Moisture Analyzer has a CE declaration of conformity and OHAUS is registered to ISO 9001 - Quality Management System.

8	MB45

1.4 Safety is first (Cont.)

Certain samples require special care!

With certain types of samples, there is a possibility of danger to personnel or damage to property through:

Fire or explosion:

— Flammable or explosive substances;

—Substances containing solvents;

—Substances which release flammable or explosive vapors when heated. With such samples, work at a drying temperature that is low enough to prevent the formation of flames or an explosion and wear protective goggles. Should there be any uncertainty regarding the flammability of a sample, always work with a small sample (maximum. 1 gram). In such cases, never leave the instrument unattended! In cases of doubt, perform a careful risk analysis.

Poisoning, burning:

—Substances which contain toxic or caustic components. Such substances may be dried only in a fume hood.

Corrosion:

—Substances which release corrosive vapors when heated (e.g. acids). In the case of such substances, we advise you to work with small amounts of samples as the vapor can condense on cooler housing parts and cause corrosion. Please note that the user always takes responsibility and assumes liability for damage caused by use of the types of samples mentioned above!

—Never make any modifications or constructional alterations to the instrument and use only original spare parts and optional equipment from Ohaus Corporation.

—Your Moisture Analyzer is a rugged, precision instrument – but you should still treat it carefully; it will then provide you with many years of trouble-free operation.

—Please comply with all notes and instructions in these operating instructions. Keep the instructions in a safe place where they are immediately at hand if any points are unclear.

APPLICATION DISCLAIMER:

—Moisture determination applications must be optimized and validated by the user according to local regulations. Application specific data provided by Ohaus is provided for reference purposes only. Ohaus waives all liability for applications based on this data.
