Grips of heater cover

Do Not Measure a Dangerous Sample.

Do not use an explosive, flammable or noxious substance as a sample. Do not use a sample that makes a dangerous substance by drying it. Do not use unknown substances.

When a sample surface becomes dry first and the inner pressure increases, the sample may explode. Do not use such a sample.

Turn off the power switch if a sample catches fire.

The case of the analyzer is made of a flame-retardant substance (UL94V0).

Do Not Put any Flammable Matter Around the Analyzer.

During and after measurement, parts of the analyzer become very hot. Do not put flammable matter near the analyzer.

Do not put any thing on the heater cover.

Caution for Heating (Drying).

When the drying temperature is set to 200°C and measurement is started, the thermostat of the halogen lamp may work after 30 minutes. When the halogen lamp has cooled down, the next measurement can be started. If necessary, change the drying time and temperature.

When a measurement is started and the time passes one hour, the maximum temperature is automatically regulated to 160°C for safety.

Operation to Stop Measurement

During measurement, the STOP key is always effective. If there is an error or danger, press the STOP key.

3.3. After Use and Maintaining the Analyzer

Put dust cover on the analyzer after it is cool.

Clean the glass-housing carefully.

Clean fingerprints from the halogen lamp to keep its life. Refer to «15.2.Replacement of the Halogen Lamp».

Avoid mechanical shock to the analyzer.

Do not disassemble the analyzer. Protect the analyzer from excessive dust.

Use the packing box (special container) to move the analyzer.

Clean the analyzer with a lint free cloth that is moistened with warm water and a mild detergent. Do not use organic solvents to clean the analyzer. Do not disassemble or remodel the analyzer.

The analyzer is equipped with a serial interface as standard. It can be connected to a printer or computer.

The analyzer can calibrate the weighing sensor (Use special mass.) and drying temperature (Use temperature calibrator for MS-70 and MX-50 except MF-50 and ML-50). The analyzer can output the data required at GLP, GMP and ISO at the end of the calibration.

The analyzer has a self check function that can detect function errors.

The analyzer displays the current change of moisture content per one minute [%/ min] in real-time. It can be used for the reference to find the analyzing mode.

The sample pans included in the standard accessory can be used repeatedly.

There is a test sample that is used to check the moisture accuracy. (The test sample is a part of standard accessory except ML-50)

The glass fiber sheets can be used to quick and precision measurement for liquid sample. (The glass fiber sheets are a part of standard accessory except ML-50)

A reference card is built into the bottom of the analyzer.

Principle and Use

The moisture analyzer, based on the principle of thermogravimetric analysis, dries a sample using a halogen lamp and obtains the moisture content in % and other results by the difference between the wet weight and dry weight.

Caution

Please confirm that the analyzer is correct for your local voltage, receptacle type and power cord.

6.3. Proper Operation for Precision Measurement

6.3.1.Operation of the sample

Use a proper sample quantity. If the quantity is small, precise results may not be possible.

If the moisture content of the sample (example: plastic) can be estimated that is less than 1%, the mass of moisture is not enough for the measurement, when measuring light sample, the result may not be accurate. Consider the following sample mass for the measurement.

If the measurement is repeated, maintain the same sample quantity.

Crush grain samples to a small, uniform powder for a quick drying process.

Spread the sample as evenly as possible.

volatile matter, it may vaporize during drying causing a measurement error.

When measuring a liquid or liquid state sample that may make a film on the surface, we recommend you use a glass fiber sheet (AX-MX-32-2).

6.3.2.Operation of the analyzer

The analyzer needs a pre-heating process before measurement. When measuring samples repeatedly or continuously, the first result is always different from the others.

The pre-heating process is as follows: Put a sample pan, instead of a sample, on the pan. Press the START key to heat it. The analyzer temperature becomes equilibrium.

Use a sample on the sample pan that has cooled to room temperature. When a sample is put on a hot sample pan, the moisture content is diffused before measurement, and precise results are not possible. We recommend you use multiple sample pans.

Do not pile up sample pans during a measurement.

Avoid drift and vibration of air conditioners. It may cause «measurement error» and

«unstable value». In particular, because MS-70 is sensitive instrument, it is necessary to consider these influences.

When the difference between ambient temperature and sample temperature is small, it may cause temperature control error.

Example: If the heating temperature is set to 50°C, it is affected by an room temperature.

Check the activation of the halogen lamp with the operation indicator.

Example: If low heating temperature is set, the brightness of halogen lamp becomes dark.

Check the activation with blinking

6.3.3.The Glass Fiber Sheets

Use the glass fiber sheet to measure the moisture content that is included in the following samples. When this sheet is used, vaporization of moisture is speeded up and moisture measurement result becomes quick and precise.

This accessory (AX-MX-32-1) is a package of 100 glass fiber sheets.

This accessory is inclued in the packing for MS-70, MX-50 and MF-50. Purchase this accessory by your order for ML-50.

Use the glass fiber sheet (AX-MX32-1) for high surface tension liquid sample.

Example 1 : «Liquid Sample» Or «Meltable Sample»

When the glass fiber sheet is used for these measurements, moisture is more apt to vaporize because of expanding the surface area and space. And the glass fiber sheet has the effect of preventing a surface film from forming at drying process.

A sample including a lot of moisture

: Milk, yogurt, soybean milk, condensed milk, ketchup, resin, liquid paste, hand soap, etc.

A sample that melts and adheres to the sample pan. Example:Chewing gums, caramel, hony, etc.

3Soak the sample into the glass fiber sheet or put the sample on the glass fiber sheet.

Liquid sample

4 Press the START key to start the measurement.

Example 2 : «If The Sample’s Surface Is Apt To Carbonize»

When the sample is covered with a glass fiber sheet, carbonization of the sample surface decreases. Therefore the measurement result becomes repeatable and precise.

Example:Hony, soybean powder, green tea leaves, cookies, etc.

No good Good Spread the sample as evenly as possible.
