WARNING

Do not use a sample that could make a dangerous chemical reaction and cause an

explosion or poisonous gas, when the sample is dried. Keep flammables away from the analyzer. Parts of the analyzer become very hot. Materials placed near it might catch fire. Do not use the analyzer in ambient ignitable gas. It may cause explosion and fire. Use a power source (voltage, frequency, outlet type) adapted to the specification of

the analyzer. If excessive voltage is used, the analyzer may overheat and be

damage or cause a fire. Turn off the power switch and remove the power cord from the power outlet, when

replacing the halogen lamp. Touching an electrode of the halogen lamp connector

carelessly, it may cause to receive an electric shock. Do not disassemble the analyzer. It may cause an err or, damage, receiving an electric

shock or fire. If the analyzer needs service or repai r, contact the l ocal A&D deal er . Avoid getting the analyzer wet. It is not a water-resistant structure. If there is leakage

of liquid into the analyzer, it may cause damage to the analyzer or receiving electric

shock. Do not look at the active halogen lamp to protect your eyes from damage. Do not drop, hit or crack the glassware including the halogen lamp, to avoid an

injury. When the halogen lamp is used beyond 5000 hours, we recommend replacing the

lamp with a new one to avoid trouble. When discarding a halogen lamp, do not break it to avoid scattering glass and injury.

CAUTION

Do not touch the heater cover, the halogen lamp, glass-housing, pan handle, sample

pan and sample without adequate protection, it could cause a burn or scald. Parts of

the analyzer are very hot when a measurement finishes. For operation, use the

specified grips of the heater cover and pan handle. Use the standard accessory

tools.

Do not touch parts affixed with the mark, because they may get very hot and

dangerous.

When the analyzer is used in a room where hot air does not diffuse, it may

unexpectedly overheat. In this case, adjust the drying temperature or move the

analyzer to a place with adequate ventilation.

Avoid leaving the analyzer in direct sunlight, as that could cause discoloration of the

case or a malfunction.

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.

4. Outline and

4.4.

The moisture analyzer is built using a super hybri d sensor (S.H.S.) ad opt ed i n an

analytical balance. Therefore, the result is more precise and gets greater repeatability. An analyzer using the S.H.S. has high sensitivity, needs only a sample quantity of a

few grams, and the analysis time becomes shorter. A 400W halogen lamp is used as the heating source and the temperature on the

sample pan can reach 200°C within two minutes. There are five analysis modes.

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 analyz er displ ays the current change of moisture content per one minute [%/ min]

in real-time. It can be used for the refer ence to find th e 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.

The Glass Fibe r Shee tThe Glass Fiber Sheet

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.

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. A sample including a lot of sugar, protein and oil Example:

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

A sample that has dark surface and is apt to carbonize Example
