Section 1 Getting to know your Moisture Analyzer
1. Getting to know your Moisture Analyzer
This section provides you with essential information on your MB45 Moisture Analyzer. Please read through the
section carefully even if you have previous experience with OHAUS Moisture Analyzers and be sure to familiarize
yourself with the safety notes.
1.1 Introduction
Thank you for deciding to purchase a MB45 Halogen Moisture Analyzer from Ohaus. Behind your instrument stands
OHAUS, a leading manufacturer of precision Moisture Analyzers, Balances, Scales and Indicators. An Aftermarket
Department with trained instrument technicians is dedicated to provide you with the fastest service possible in the
event your instrument requires servicing. OHAUS also has a Customer Service Department to answer any inquiries
regarding applications and accessories.
To ensure you make full use of the possibilities offered by your Moisture Analyzer, please read the manual completely
before installation and operation.
1.2 Overview of the Moisture Analyzer
The Moisture Analyzer offers a high level of operating convenience and useful functions to make accurate measure
ments.
The Moisture Analyzer has the following features:
Up to twice as fast as IR Moisture Analyzers.
Fully programmable with front panel controls.
Extremely rugged and chemically resistant construction.
Ergonomic operating controls and a large, easily readable display.
Easy to follow menus for simplified operation.
Built in functions for manual, automatic timing, printing intervals, and custom units.
Built in selectable drying profiles.
Able to set step heating levels to accommodate a variety of sample types.
Built in library stores up to 50 samples complete with setup parameters and statistics.
Built in RS232 communication interface.
Any of five languages (English, Spanish, French, German, Italian) are selectable on the display.
Display contains all test data during drying process.
A variety of accessories includes disposable pan liners, calibration mass, temperature calibration kit, interface
communication cables, printer, and a security device.
1.3 What 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 mois
ture 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.

Getting to know your Moisture Analyzer Section 1
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. Re
sponse 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.
